You don’t always have to start at 1. You can count from any number.
Key idea
Start at the number you are given and keep going: 6, 7, 8, 9 …
Why it works
The count from 1 to 6 is already done. Starting at 6 skips the part you already know, so it is quicker, and the numbers after 6 are the same as always.
Worked example: Counting on from 13
Count on from 13 up to 17.
- Start at 13.
- Keep going: 14, 15, 16, 17.
Answer: 13, 14, 15, 16, 17
Common mistake
Going back to 1 every time. Instead, put the start number “in your head”: tap your head, say it, then count on.
For grown-ups: Play “start at” games: “Start at 8 and count to 15.” Take turns being the one who picks the start.
