“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
Full guide and materials
- 20 large blocks or toys for pairs
- Paper number line or hundred chart
- Optional five-frame or ten-frame drawings
- Step 1. Make pairs of blocks up to 20 and chant 2, 4, 6, 8 … 20 while pointing to each pair.
- Step 2. On the chart, color or tap every fifth number and chant 5, 10, 15 … to at least 50.
- Step 3. Tap each ten on the chart and chant 10, 20, 30 … to 100.
- Step 4. Cover the chart and ask for one sequence from memory, then check against the chart.
- Quick check. Success means your child skip-counts by 2s to at least 20, by 5s to at least 50, and by 10s to 100 with at most one restart per sequence.
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.”

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?”
