About this game

Even, odd and skip counting

Even, odd and skip counting: a free Grade 2 math game for ages 7-8. Kids tell even from odd and find the next number when counting by 2s, 5s, 10s or 100s. 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

Each round of Even, odd and skip counting mixes two kinds of card. One asks whether a number from 1 to 20 is even or odd, with two buttons to tap. The other shows three numbers counting by 2s, 5s, 10s or 100s, such as 40, 42, 44, and your child types the next one. Only twenty numbers feed the even-odd cards, so one can come back. Ten cards make a round in this Grade 2 game, and each answer is checked.

Both kinds rest on patterns in counting. Even means a number splits into pairs with none left over, and the hint suggests trying exactly that. Skip counting adds the same amount each time. Noticing that even numbers end in 0, 2, 4, 6 or 8 links the two: counting by 2s from 40 only ever lands on even numbers.

Habit can shrink the last jump. On 130, 135, 140, typing 141 slips back to counting by ones. Ask, "How big was each jump so far?" Then count the gap on fingers. Finish with, "You kept every jump the same size."
