Learning from Mistakes!

Like many teachers and math coaches, I have often thought about missed opportunities for learning when I see mistakes in students’ work, and I long for ways to have students engage with misconceptions and errors. For as Jo Boaler explains about why mistakes cause your brain to grow: 

When teachers ask me how this can be possible, I tell them that the best thinking we have on this now is that the brain sparks and grows when we make a mistake, even if we are not aware of it, because it is a time of struggle; the brain is challenged and the challenge results in growth.

I am excited about Nancy Anderson’s new book, What’s Right About Wrong Answers: Learning from Math Mistakes, Grades 4-5. She provides twenty-two error analysis tasks for students that focus on common misconceptions. Each task, presented on a handout, is part of an activity including independent work, partner work, group discussion tasks and extension problems. The handouts are presented in 3 different engaging formats, comic strips, letters, and sample student work. Teacher notes for using the activities are clear and easy to follow. The combination of discussing the misconceptions of fictionalized students and working on similar problems, invites students to talk about mistakes and reflect on their own misconceptions.

In her introduction, Nancy personalizes the importance of students reflecting on their own errors. Reflecting on her own experiences in math, she writes, “I didn’t need explanations that focused on correct solution strategies but help in finding the flaw in my approach… to identify and unravel my misconceptions and use my mistakes to find correct solutions.” Isn’t that what we want for our students?

Reading the book led me to search for other resources focusing on math mistakes. The format for error-analysis activities in What’s Right About Wrong Answers seems to be unique. But there are many other wonderful resources with insights about students’ mistakes and misconceptions. I found the following books and websites:

By NCTM President Linda M. Gojak
NCTM Summing Up, January 8, 2013

Linda quotes Norman Juster’s wonderful book The Phantom Tollbooth. I fondly remember reading this to my third and fourth grade students and discussing the role of making mistakes in learning

“It has been a long trip,” said Milo, climbing onto the couch where the princesses sat; “but we would have been here much sooner if I hadn’t made so many mistakes. I’m afraid it’s all my fault.”

“You must never feel badly about making mistakes,” explained Reason quietly, “as long as you take the trouble to learn from them. For you often learn more by being wrong for the right reasons than you do by being right for the wrong reasons.” 
―  Norton Juster,  The Phantom Tollbooth

Let’s keep helping our students engage in learning from mistakes!

 

Engage Students as Accountable Listeners!

Wondering about steps to help engage all students in meaningful math discussions? I believe that telling “students what to listen for” helps students learn to engage fully in discussions. Damon Bahr and Kim Bahr describe four steps that enhance listening  in their February 2017 TCM article Engaging All Students in Mathematical Discussions.

By telling students what to listen for, more students think about how what they hear connects to a purpose or idea. They can be held accountable for this listening. You can even call on students at random, as the authors suggest, increasing participation. We can model and teach listening and then use routines to get all students engaged.

You can model students working to listen with purpose by reading and discussing my Use Your Math Power picture books. Your students can analyze what the books’ characters are being asked to listen for and how they follow through. Teachers looking for instructional moves to enhance discussions can analyze how Ms. Green, the teacher, helps her students listen more effectively.

In Monkeys for the Zoo, Ms. Green reads a problem twice and tells her students, “Now talk about this problem with your partner. Get ready to tell us what you think this problem is about.” After partners have shared, she says “Carlos, tell us what you and your partner think. Then we can act it out.” With these instructions she gives students a specific purpose by telling them how they will use what they hear.

Later she asks, “What is Ellie’s idea? Will it work?” By telling students to focus on whether the idea will work, she lets them know she will hold them accountable for thinking about their classmates’ explanations.

 

There are similar examples in Hatching Butterflies and Penguins on Parade. One of my favorites is in Hatching Butterflies when a pair of students is getting ready to share their problem solving strategy with the class. Ms. Green says, “Listen carefully, everyone. Then you’ll be able to explain what they did.”

Once the pair of students has finished sharing, Ms. Green calls on a student randomly to explain the strategy. Then she asks if there are any questions. Because the listeners were really thinking about the strategy, they raise questions about unclear parts of the explanation. This is the kind of listening and interaction that empowers students as thinkers and learners. Careful listening was key!

I highly recommend focusing on listening to help enhance math discourse in your classroom. I hope the article Engaging All Students in Mathematical Discussions and my Use Your Math Power books can help you in this endeavor.

REASONING ABOUT PLACE VALUE IN CONTEXT

 

screen-shot-2016-10-04-at-12-47-02-pm

My picture book Penguins on Parade uses a purely fanciful problem to illustrate students making sense of counting by tens from a number that doesn’t have zero in the ones place. The characters in the book enjoy imagining the penguin parade starting with 8 penguins followed by groups of 10 penguins. Their teacher Ms. Green asks them to figure out how they could count the penguins by tens starting at 8. Share this book with your class and show them characters deepening their understanding of tens and ones as they tackle an unfamiliar problem.screen-shot-2016-10-04-at-12-48-28-pm

Trevor is frustrated by this problem since he’s never been told how to do it. But his partner Zoe perseveres and engages him in using Ten-Frame Cards with dots on them to help them figure out the subtotals for the count. Then they examine their list, 8, 18, 28, 38, with their classmates and begin to understand why adding on a ten increases the number in the tens place while the number in the ones place remains the same.

screen-shot-2016-10-04-at-12-49-29-pm

 

Two other classmates Ellie and Kayla use an open number line (or empty number line) to help them figure out what they get when they add tens onto 8. They break up each ten into a 2 and an 8 to make the fewest jumps they can to add on a ten. They know it is efficient to jump to the next multiple of ten and then add on the amount left in the ten. They are applying their knowledge of the number pairs that make ten and their understanding of counting up and down on a number line.

screen-shot-2016-10-04-at-12-50-31-pm

Explorations like this are much more powerful than just remembering which place is the ones place, which place is the tens place and adding ones to ones and tens to tens. Experiences like this help students understand that the 4 in 47 means 4 because it is 4 tens, but also means 40 because 4 tens are 40.

The characters in the book model how they are learning to use the Standards for Mathematical Practice. Your students will see this class sharing ideas and helping Trevor gain confidence in his ability to make sense of new problems!

TCM Article; Stimulating Math Thinking and Critiquing of Reasoning

 

screen-shot-2016-09-24-at-12-25-09-pm

Here is a technique that helps me engage students in thinking that deepens their understanding. I ask students to consider a strategy or idea that I say came from a student they don’t know, someone in another classroom or another year. Many times the student is fictitious. By using this strategy I can introduce an important concept or skill without suggesting that the ideas comes from me. Bringing up ideas in this way stimulates student thinking and discussion, so I frequently suggest that teachers do the same. It is sort of like asking a “what if” question, but making it personal, but non-threatening for the children in the classroom.

I was excited to read the cover story in the September 2016 issue of Teaching Children Mathematics, “Learning from the Unknown Student” (by Angela T. Barlow, Natasha E. Gerstenschlager, and Shannon E. Harmon).The article illustrates three different types of situations for using this strategy and explains the value in each one. The article clearly presented three purposes for using promoting learning with the work of an “unknown student” effectively:

  • To introduce strategies that students aren’t bringing up in class
  • To help students gain comfort in critiquing the work of others
  • To introduce unfamiliar processes and procedures in a way that engages thinking and comparing to other strategies

The authors explained how using this strategy in classrooms has teachers promote use of the Standards of Mathematical Practice and gave useful guidelines for using the strategy. Thank you to the authors for this helpful article!

 

Persevering and Making Connections; Problems with More than One Solution

Elementary students can find it challenging to solve  problems with more than one solution, especially if they have never worked through this type of problem before.   Some students have the idea that every math problem has only one solution.   So working with  the Common Addition and Subtraction Situations: Put Together- Both Addends Unknown  (http://www.corestandards.org/Math/Content/mathematics-glossary/Table-1/) can help students learn more about persevering to solve unfamiliar problems. My picture book, Monkeys for the Zoo presents a model of students engaging in such a problem.

Screen Shot 2016-03-13 at 1.54.21 PM

 

Working with this problem, Ms. Green’s students find out that some problems do have more than one possible solution. Mia sees that if you can have 3 howler monkeys and 10 spider monkeys, you could also have 10 howler monkeys and 3 spider monkeys. Then she discovers that you could change that combination to have 9 howler monkeys and 4 spider monkeys. And Jayden uses 9 + 4 to come up with 8 + 5. This problem pushes students to see the relationships between combinations and use one combination to find another.

 

Screen Shot 2016-09-03 at 12.11.13 PM

Present your students with one of these problems. On the last page in Monkeys for the Zoo there are several suggestions, or you might make one up about another context that your students would enjoy thinking about. Students will find different entry points and enjoy working together to see how many solutions they can find. At first, some students may not accept that more than one combination of addends will work. They may be satisfied with only a few of the possible solutions. Involve them in modeling the problem and discussing solutions with their peers to help them see that there are many possibilities. Ask questions like:
“Who used one combination to help you find another? How did it help you?”
“If this combination works, how can we use it to find another?”
“What are some other ways you can use one solution to help you find another?”
For students struggling with this idea, reexamine Monkeys for the Zoo, and ask, “How do you think Rosie used the solution 3 howlers and 10 spiders to get 3 spiders and 10 howlers? How do you think Mia used 3 spiders and 10 howlers to help her find 4 spiders and 9 howlers?”

EXTENDING THE PROBLEM
When students are ready, see if they can find all of the possible solutions. Have students discuss how they know they have all the combinations, what strategies helped them find all the combinations, and which combination of addends are preferable in particular real world situations. For another challenge, you can add conditions to situations where both addends are unknown. For example, consider this problem: Juan has 8 books. He wants to put more books on his shelf than next to his bed. How many might he put next to his bed and how many might he put on his shelf? Your students may also enjoy the challenge of making up their own unknown addend problems.

Reflecting On Our Questioning

When teachers  want hints for facilitating discussions,  we often talk about the importance of questioning that engages student thinking. I want to pass on 3 pieces that I think help teachers reflect on their questioning.

First, an article that was recently posted on Twitter.  This article “Questioning Our Patterns of Questioning” from Mathematics Teaching in the Middle School, 2005, is relevant for all ages.  It differentiates between “funneling” patterns where “the teacher asks a series of questions that guide students through a procedure or to a desired end” and “focusing” patterns where the teacher’s questions are based on students’ thinking.  The article uses several examples to illustrate these patterns.  It also suggests how teachers can reflect on their own questioning practice by making an audio recording of a classroom discussion and then analyzing their own questioning patterns.  Here is the link to the article: Focusing with Questioning nctm.

Another helpful resource is a talk Graham Fletcher gave on  April 13, 2016, called “The Less I Talk, the More I’m Listened To”.  He gave it at The Math Forum, NCTM Ignite event at the 2016 NCSM Annual Conference in Oakland, CA.  It really makes you think about who does the talking in math class.  Here is the web address:  http://bit.ly/29PAsQE

And then, an article I’ve been recommending for years, “Never Say Anything A Kid Can Say” by Steven C. Reinhart, also from Mathematics Teaching in the Middle School, but so relevant for all grades.  Mr. Reinhart talks about how he learned to ask “good questions” that brought students to engage more effectively and take greater responsibility for their learning.  Now when I am facilitating a math discussion, I often think to myself, “Never say anything a kid can say.”  I try to ask questions that will get the participants to delve into understanding the concepts at hand and explaining what they understand?  Click here for the article.

Lesson Plans for Use Your Math Power Books

I  have written lesson plans to help teachers use the UYMP books to engage students in  understanding and use the practices.  These lessons and the introduction are available here as pdfs.  The introduction is pasted below to give you more information about the lessons.  Here are the pdfs for the introduction and the lesson plans.

Use Your Math Power Books: A Model for Mathematical Practices and Opportunities for Student Reflection

 Goal: The following lessons guide the teacher in using the Use Your Math Power books to model mathematical practices and give students opportunities to reflect on how they can enhance their use of the practices, focusing on participation, perseverance, and communication.

Thinking behind the lessons:  By reading and reflecting on the Use Your Math Power books, math students can reflect on how they can use best practices and engage in a learning community. In the lessons, students focus on practices that help them succeed in math. The lessons can be used early in the year to set expectations, or during the year to reinforce best practices.

Though set in a primary classroom, these books provide a tool for students of various ages to think about mathematical practices, especially perseverance and communication. Older students listening to the books may find it easier to focus on the practices since the math content will be less challenging.   When used in first grade, teachers may wish to wait to use each books until the time of year when they are working on the math content in the book’s problem.

The Lessons:  There are 3 lessons for each book, a first reading, a lesson focusing on a common struggle in classroom participation, and one focusing on effective communication.

Hatching Butterflies   1. A First Reading, 2. Working with Partners,  3. Focusing on Communication

Monkeys for the Zoo  1. A First Reading,  2. Gaining Confidence to Share Your Ideas,  3. Focusing on Communication

Penguins on Parade  1. A First Reading,   2. Making Sense of Unfamiliar Problems,  3. Focusing on Communication

Equal Opportunities for Struggle!

I love this quote from Cathy Seeley, shared today on twitter from an NCSM talk.

“Protecting students from (the right kind of) struggling is one of the worst ways we treat students inequitably.”

I so agree! All of our students need opportunities to work through struggles.  If we ask questions, listen carefully to students’ ideas, and have them discuss their thinking with each other, we can provide prompts that help them access their prior knowledge and make sense of unfamiliar problems.

As an example, I am sharing some pages  from Penguins on Parade.   The teacher, Ms. Green, helps her primary students learn to work through struggles with unfamiliar tasks.  First she asks her students to think about an imaginary parade of penguins.

Screen Shot 2016-04-13 at 2.00.18 PM

In a few pages, Jayden has a suggestion.  Ms. Green asks her students to try to work with partners and figure out how to count in an unfamiliar way.

Screen Shot 2016-04-13 at 2.01.14 PM

Screen Shot 2016-04-13 at 2.01.31 PM

Trevor reluctantly works with Zoe, trying to use the ten frames to count the penguins by tens starting from 8.  As Zoe adds tens they count by ones and she records each subtotal in a list.  Then we see them talking about whether they are counting by tens.

Screen Shot peng. p. 14

Screen Shot peng. p. 15

Once they share their work with the class, another student sees their pattern and figures out that 48 will be next.  The students work together to check and see that 48 is correct.  Then they continue to try to use the pattern and discuss why it works.Screen Shot 2016-04-13 at 2.04.32 PM

The discussion continues.  These primary students are learning to reason about mathematics, providing a model for students and teachers.  They are learning to work through accessible (the right kind of) struggles without their teacher giving them too much protection!
