Use AI to help with two-step word problems

You use the AI. Your child does the thinking. This page explains how the class teaches two-step word problems and what to say tonight, and it has a free practice sheet with the answer key on its own page.

If you use AI: snap one problem, get help and more practice

Already seeing your child photograph homework so AI can solve it? This box is the grown-up version: the AI gives you hints and new practice, and your child still works the problem on paper.

For a problem that isn’t like the ones on our sheet, use your own AI account to get it explained and get 5 more like it. The photo goes to your AI account and never reaches AiWhizzkids.

Where AI can go wrong on this skill

AI may write practice problems that only take one step, or answer step 1 and stop. Check that every new problem needs two steps and that the key answers the question that was asked.

  1. Photograph one printed problem only. Crop out your child’s name, school, teacher and handwriting.
  2. Open your own AI account (ChatGPT, Gemini or similar). Most require users to be 13 or older, so you hold the phone.
  3. Upload the photo and paste this prompt:
    This is a math problem from my child's 3rd-grade homework. Please help me, the parent.
1. Type the problem back exactly as you see it, including any words. If a picture, table or diagram is part of it, describe it in words. If anything is unclear or cut off, say so instead of guessing.
2. Tell me what kind of problem this is (for example a two-step word problem, the distributive property, regrouping or an area model) and which strategy the worksheet seems to want.
3. Explain that strategy to me in plain words, the way a 3rd-grade teacher would, in 5 sentences or fewer. Don't use a shortcut my child hasn't learned.
4. Give me 3 questions I can ask my child to get started. Hints only, no answers.
5. Write 5 new practice problems of the same type, with the same strategy and the same size of numbers. Number them. No answers next to them.
6. Put an answer key at the very end, with one line of working for each.
Don't solve the original problem. My child will do that.
Make every new problem take two steps, with the same two operations in the same order as this one.
Keep the same kind of story, but change the names, things and numbers.
  4. Check before you print:
    • Does the problem it typed back match the photo exactly?
    • Did it name the same strategy your child’s worksheet uses?
    • Work one new problem yourself and compare it with the key.
    • If the problem has a picture (an array, a number line, a clock), check the AI’s description of it. If the description is wrong, type the problem out instead of using the photo.
    • If anything looks off, ask again in a new chat. If two answers differ, trust neither.
    • Does every new problem take two steps, with the same two operations?
    • Read each new problem. Does it make sense?

How your child’s class teaches it

A two-step word problem needs two calculations, and the second one uses the answer to the first. “There are 3 packs of 6 juice boxes. The class drinks 4. How many are left?” Step 1 is 3 × 6 = 18 juice boxes. Step 2 is 18 − 4 = 14.

Step 1: 3 × 6 = 18. Step 2: 18 − 4 = 14 juice boxes left.

The first step is often hidden. The question asks how many are left, and nobody says how many there were to begin with, so your child has to work that out first. In 3rd grade the two steps can use any of the four operations, in either order, such as adding first and then multiplying.

Many classes also ask children to write the whole problem as one equation, with a letter for the answer: j = 3 × 6 − 4. Multiplication and division come before addition and subtraction, so this works out as 18 − 4 = 14. When the adding has to happen first, worksheets use parentheses: (5 + 2) × 4 means add first, then multiply.

Your child’s class will also ask whether the answer makes sense. If 3 packs of 6 left 40 juice boxes, something went wrong, because there were only 18 to begin with.

In the Common Core standards, this is 3.OA.8. Texas, Florida, Virginia and some other states use their own standards, so follow the method on your child’s worksheet.

What to say tonight

“What does the question ask? What do you need to find out first?”

“What’s your first step? What do you do with that answer?”

“Does your answer make sense? Is it about the right size?”

The mistake to watch for

The usual slip is stopping after step 1. Your child works out 3 × 6 = 18 and writes 18, forgetting the 4 juice boxes the class drank. Ask, “Read the question again. Is 18 what it asks for?”

The other slip is choosing operations from single words. “More” doesn’t always mean add, and “each” doesn’t always mean multiply. Before your child calculates, have them say what each step does: “First I find how many there are in all, then I take away the ones they drank.”

Free practice sheet

The sheet has 10 problems on one page: 4 story problems with the two steps set out, 3 to solve in two steps and 3 to write as an equation with a letter. The answer key is on page 2, so you can print page 1 on its own.

Page 1 of the two-step word problems practice sheet: four story problems with step lines, three with a work box and three to write as an equation.

Rather skip the AI account? We’re thinking about building the photo step into this page.

Snap your worksheet (beta)

It isn’t built yet. The idea: you take a photo of one printed problem, and this page names the problem type and makes matching practice with an answer key, with no AI account of your own. If you’d use it, join the waitlist. If enough parents want it, we’ll build it and email you first.

Your email is the only thing we keep. Nothing is uploaded, and nothing about your child is collected. You’ll also get our emails for parents, and you can unsubscribe whenever you like.
