Parent guide
Odd and even is one of the first big sorting ideas in math. In Grade 1, kids learn that even numbers can be split into two equal groups with nothing left, while odd numbers always leave one extra.
Most first graders meet even numbers within 20 first. They notice that 2, 4, 6, 8 and 10 come in pairs. The surprise comes when numbers get larger. A number like 38 looks hard, but the rule still holds.
Start with Even numbers within 20, then swap to Odd numbers within 20 so your kid sees both sides. When that is steady, try the sheets that stretch to 100. Here the last digit does all the work. Only 0, 2, 4, 6 and 8 mark an even number, no matter how big it is.
Pay attention to numbers such as 10 and 12, where two digits can distract your kid. If they stall, hand over a few counters and pair them up. When a row of ten numbers takes under a minute and comes out right, move on.
