About this game

Count by 10s

Count by 10s: a free Kindergarten math game for ages 5-6. Kids count by tens and pick the number that comes next. Each round brings 10 fresh questions with new numbers; instructions are read aloud and every answer is checked.

How it plays and why it helps

Ten fingers, then ten more: counting by tens can start with two hands held up again and again. Count by 10s shows three numbers in a row, such as 30, 40, 50, and a missing fourth. Your child taps the right number among three. The list is short, seven rows, so a card can come back in the same round of ten. This Kindergarten game reads each instruction aloud and checks each tap.

Counting by tens is an early step toward place value. Each jump adds one ten. The ones stay at zero. The hint says it simply: each number is 10 more than the one before. One row climbs from 90 to 100, a brand-new word for many five-year-olds, so it is worth saying together.

After 90, habit can take over. On 70, 80, 90, the choice 91 just counts one more. Point at the zeros and ask, "Did the others go up by one?" Hold up ten fingers for the jump. Then say, "You found one hundred after ninety."
