Sorting & Classifying

Putting things in groups, then saying what made the group.

Sorting buttons looks like play. Where’s the math?

It’s in the rule. Dump out a jar of buttons and there’s no single right way to sort them: by color, by size, by whether they’ve got holes. Your child picks a rule, sticks to it, then says what it was. That last part is the hard one.

What each age is working on

The codes beside each line are the state’s own labels: Texas writes Prekindergarten Guidelines for Pre-K, and TEKS from Kindergarten up.
