Same math. New drawings.

Your child’s math homework might not look like the math you learned: number lines, strip diagrams, place value disks, arrows. It’s the same arithmetic, drawn out so kids can see why it works. Every page here shows what one of those drawings means, beside the way you learned it.

Stuck on tonight’s homework?

  1. Look at the drawing on the paper: a number line, a bar split into parts, circles in columns.
  2. Open the chart for that kind of problem, below, and find the drawing that matches.
  3. Read it beside the way you learned it, then sit down with your child.

You don’t have to learn it their way. You just have to recognize it.

Younger child? Pre-K and Kindergarten has six early math skills, with sample pages for each.

Questions families ask

Do I need an account?
No. Every page is open to read, and nothing is collected about any student.
Do I have to do it their way?
No. Your way still works. Seeing both side by side helps you show your child how the two connect.
Is it in Spanish?
Yes. Every page has a Spanish version: use Español at the top of any page. It’s a first draft, and corrections are welcome.
