Gakuva’s recommended starting approach is selected. You can still compare every option.

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?”
