Ten fingers, ten toes, one big idea
Base 10 sounds fancy, but for preschoolers it starts with one friendly number: ten. Little learners count to 10 (and many to 20), match each number to a group of objects, and notice that ten is a special, full group, just like ten fingers on two hands. Filling a ten frame is a favorite: when all ten boxes have a counter, the frame is full! That early sense of "a full group of ten" is the seed for place value in kindergarten and first grade, when kids learn that 12 = 10 + 2.
Preschool math should be loud, hands-on and joyful. These are the moves we use most.
Songs give kids a steady beat to count along with, and they hold up a finger for every number. Sing the counting song twice a day for a week and watch kids count to 10 without stopping. Then have them hold up "all ten" proudly at the end.
Why it works: words set to a repeating melody are easier to recall than the same words spoken (Wallace, 1994).

Why it works: going from real objects to pictures to symbols is a core recommendation of the U.S. Department of Education's elementary math guide.
Count out ten craft sticks together and wrap them with a rubber band. "Look, this is one ten!" Let kids make their own bundles. Holding a ten in their hand turns an abstract idea into something they can feel.
Why it works: playful practice with a clear goal keeps kids practicing longer, and simple learning games have been shown to build real skills (Ramani and Siegler, 2008).
For preschoolers, base 10 means getting comfortable with the number ten as a full group. Kids count to 10, match numbers to objects and fill ten frames. Place value comes later, but this is the foundation.
A ten frame is a rectangle split into ten boxes, two rows of five. Kids place one counter in each box. It helps them see numbers at a glance and notice how many more make ten.
Many preschoolers count to 10 by age four and to 20 by the end of pre-K. Counting objects one by one, with one number for each item, matters just as much as saying the numbers in order.
Count stairs, snacks, toys and fingers throughout the day. Sing counting songs in the car. Short, playful moments every day build number sense better than sitting down to drill.
