Teen numbers: a worked example (10 and 6 more)
- Start with the ten: a full rod or a full ten frame is 10.
- Count the loose ones: there are 6.
- 10 and 6 is sixteen.
- Write it as 16: the 1 is the ten and the 6 is the six ones.
How to use it at home and in class
At home
Use real tens: a bundle of 10 straws, an egg box with 10 eggs or a full ten frame. Ask your child to build each number with the ten and some loose ones before writing it. Say both ways every time: “sixteen is 10 and 6.” Part E has the number words, so read them aloud first. The teen numbers lesson shows each one with pictures. Ten problems a day works better than a whole sheet at once. Mark them together with the answer key, then ask your child to explain one they got wrong: finding the mistake themselves is where the learning happens.
In class
Use the first row as a warm-up, a full page for independent practice, or five questions as an exit ticket. For a retake or a second group, make a new version with the test maker so every child gets different numbers.
Mistakes to watch for
- Writing 61 for sixteen, because the word says “six” first.
- Writing 106 for 10 and 6, putting the 10 and the 6 side by side.
- Not knowing that eleven and twelve are 10 and 1, and 10 and 2.
- Thinking the 1 in 14 means one thing instead of one ten.
What to practice before and after teen numbers
- Before: ten frames. If this sheet is a struggle, go back a step.
- After: number line, once this one is mostly right.
- Learn it first: the teen numbers lesson.
