Counting in 2s
Count in multiples of 2, 5, and 10 (skip counting)
Lesson
Set out your lesson
“Skip counting jumps by the same amount each time. Twos sound like 2, 4, 6, 8. Fives sound like 5, 10, 15, 20. Tens sound like 10, 20, 30… up the decades.”
Bring to the table
- 20 large blocks or toys for pairs
- Paper number line or hundred chart
- Optional five-frame or ten-frame drawings
Extra for the adult
Worked example. Pairs: 2, 4, 6, 8, 10, 12, 14, 16, 18, 20. Fives: 5, 10, 15, 20, 25, 30, 35, 40, 45, 50. Tens: 10, 20, 30 … 100.
Optional challenge. Start at 4 and count by 2s to 20, or start at 15 and count by 5s to 50.
What to notice. Save a parent note listing the three sequences reached, such as “2s to 20, 5s to 50, 10s to 100.”

2 approaches
Skip counting jumps by the same amount each time. Twos sound like 2, 4, 6, 8. Fives sound like 5, 10, 15, 20. Tens sound like 10, 20, 30… up the decades.
Spend about 15 minutes skip-counting by 2s, 5s, and 10s with objects first, then with the chart.
Skip-count in twos to 20, fives to 50 and tens to 100, connecting each step with a group.

“If your child is counting socks being paired up, can they skip-count in twos — 2, 4, 6, 8 — all the way to 20? Can they also count up in fives when counting coins, or in tens on a number line?”
