Counting by twos supports a variety of other mathematical tasks. Counting by twos allows students to count more quickly. More importantly counting by twos supports doubling, pairs and grouping for multiplication. Here are some activities you can do to help your child learn to count by two numbers and understand what it means to count by two.
- Take turns counting. You say “1”, your child says “2”, you say “3”, your child says “4”, etc. through 20. Do the counting again but this time you whisper (your child still says the number out loud). The third time you just mouth the number but your child still says the number out loud. This will reinforce the counting by twos skills.
- Think of a toy that is both small and interesting, that already belongs to your child. Legos, blocks, cars, etc. Play a game where you set out a pile and ask your child to figure out how many. Your child should touch two and count two as he/she pushes them away from the pile. Also, when he/she is done counting, ask if every item had a partner. Ask if the group was even (each item had a partner) or odd (one item was left without a partner). Take turns selecting and then counting piles.
