How to support productive struggle in middle school math

How to keep every student in grades 4-8 working on math that makes them think, with feedback on each mistake while they still remember how they made it.

Title card reading 'How to support productive struggle in middle school math', next to three students' cards from a ratios and proportions practice: a student who solved a problem with no hints and moved up a level, a student who set up a proportion upside down and found the mistake, and a student stuck on a map scale problem who gets one more at the same level.

"My students are able to engage in interactive lessons that challenge them without overwhelming them. AI has made it easier for them to understand concepts by providing immediate feedback, allowing them to learn from their mistakes in real-time."

Rooban ArumugamRooban Arumugam, Lower School Math and English Teacher at SJK(T) Selama

Why this matters

In one grade 7 class, a student finishes the ratio problems in five minutes and waits for more. The classmate next to her sets up every proportion upside down and gets 5⅓ cups of flour where the recipe needs 12. The first student learns nothing new, the second practices the same mistake ten times, and the teacher has to wait for quiz day to find out.

What productive struggle in math looks like

Productive struggle is the effort students spend making sense of a math problem that isn't clear to them yet. NCTM lists supporting it as one of eight effective teaching practices: give students time to struggle, and ask questions that move their thinking forward without doing the work for them (NCTM's Principles to Actions, summarized by the Colorado Department of Education).

  1. Give each student a problem that is a little hard for them
  2. Ask a question instead of fixing the mistake
  3. Give feedback right after each answer

A teacher with 30 students can't raise the level for every student who is ready and ask the right question about every mistake while it's fresh. Sparky, Flint's AI tutor, does it in each student's chat.

One ratio problem, practiced by two students

Both students are in the same ratios and proportions practice, and Sparky opens both chats with the same question. Each student has their own chat, and the problems after the first one depend on their answers.

E

Eli

Feeling: ConfidentStarting point: Solves proportions quickly

Sparky

How sure do you feel about ratios: new to you, okay, or confident?

Eli

Confident.

Understanding check

A recipe uses 3 cups of flour for every 2 cups of sugar. How many cups of flour go with 8 cups of sugar?

Eli

3/2 = x/8, so x = 12. 12 cups.

Sparky

Right, with no hints. Here's a harder one. A map's scale is 1 inch = 25 miles. Two cities are 3.5 inches apart on the map. How many miles apart are they?

Eli

I don't know where to start.

Sparky

The scale is a ratio: 1 inch to 25 miles. Can you write it as a fraction and set it equal to one with 3.5 inches?

Eli

1/25 = 3.5/x, so x = 25 × 3.5 = 87.5 miles.

Sparky

That's right. You needed one hint, so here's one more scale problem before we move on.

Moved up a level, then solved it with one hint

Z

Zoe

Feeling: Okay with ratiosStarting point: Knows ratio tables, new to proportions

Sparky

How sure do you feel about ratios: new to you, okay, or confident?

Zoe

Okay, I think.

Understanding check

A recipe uses 3 cups of flour for every 2 cups of sugar. How many cups of flour go with 8 cups of sugar?

Zoe

2/3 = x/8. 3x = 16, so x = 5.33 cups.

Sparky

There's a mistake in your setup. Check which quantity goes on top of each ratio: in the recipe, which number goes with flour and which goes with sugar?

Zoe

3 is the flour and 2 is the sugar, so I flipped the first ratio. 3/2 = x/8, and x = 12.

Sparky

That's right, and you found the mistake yourself. You needed one hint, so here's one more like it before we move up.

Found the flipped ratio and fixed it

Eli gets a harder problem as soon as he solves the first one, and when he's stuck, Sparky gives the smallest hint instead of the answer. Zoe hears right away that something is off, and Sparky asks her to find the mistake instead of fixing it. The students and chats are examples we wrote for this page. The activity's guidelines tell Sparky to do both.

See who is stuck and who fixed their own mistakes

Sparky grades each chat against your rubric. The activity page shows who needs help right now, what the class does well, and what to practice next.

Flint's activity page for an activity called Ratios and Proportions: Practice That Gets Harder. Needs attention shows a live alert that one student wrote 'this is too hard' after two hints on the same unit price problem. Activity analytics lists what the class does well, including 9 students who found their own mistake, an area of improvement where 6 students put the quantities in a different order in each ratio, and a follow-up with a button to create a follow-up activity. The Sessions table shows two submitted students graded Proficient and one still in progress.

Example activity page

After a class finishes the ratios and proportions practice

The school and students are made up for this page. In this example, most of the class handles unit rates, and the area to practice is keeping each ratio in the same order.

Set up the activity for free

The ratios and proportions practice is in Flint's public library, with Sparky's role, guidelines, greeting and a rubric already written. Open it, select Try this activity to copy it into a free Flint account, and move it to a class. Every student gets their own chat with Sparky, and the activity page fills in as they work. In the activity settings, select Try session myself to test the activity as a student before you assign it.

For grades 4 and 5, replace the list of levels in Guidelines for Sparky with your own unit. For example:

Example guideline

Levels, in order: 1. Equivalent fractions on a number line. 2. Comparing fractions with unlike denominators. 3. Adding fractions with unlike denominators. 4. Fraction word problems. When an answer is wrong, ask the student to find the mistake instead of correcting it.
