Problem Solvers: A Free Early Math Curriculum

Problem Solvers

A Free Preschool and Early Math Curriculum

Research tells us early math skills are a powerful predictor of overall school achievement. But what does “early math” look like for toddlers and young preschoolers? It looks like Problem Solvers.

Problem Solvers is a free, downloadable early math curriculum for children aged 30 to 48 months that includes:

  • 22 play-based preschool and early math activities, spanning 7 domains of early math
  • 22 specially-composed songs that support early math learning in each activity
  • 22 book suggestions and extension activities that nurture early math language through read-alouds
  • 22 parent resources (English/Spanish) that build bridges between school and home, and give parents ideas for engaging math play
  • A Teacher’s Guide to help educators implement the curriculum

The development of Problem Solvers was made possible by the generous support of the Honda USA Foundation and the Dr. Seuss Foundation. We are deeply grateful to both foundations for allowing us to make this resource available to preschool and early education programs nationwide.

What are early educators saying about Problem Solvers?


Problem Solvers helped us connect math to books, music, and free play. That was something new for me—fresh and different.

It’s always been hard to think of different math activities so this curriculum gave us more ideas and resources!

We have a full curriculum and we were still able to add Problem Solvers as an additional piece—and it wasn’t overwhelming. The kids wanted it and asked for it, even if the teachers missed it that day.

We saw the children focusing on this new math language and using it throughout the classroom – Is it longer? Is it more? Making lots of comparisons, doing lots of counting.
