Wondering what your students are doing in math these days? The authors of our math curriculum, Investigations in Number, Data and Space, have published letters that aim to explain the mathematics taught in each unit from grades K-5, along with suggestions for parents to support their students at home.

Click on the links page and look for your child’s grade. There are usually two letters per unit. The first explains the math in the unit and the second includes related activities to try at home.
