Teen numbers are ten and some more
Thirteen is a full ten-frame and three left over. That is the whole idea of place value.
What this skill is
The ten-frame externalises the benchmarks of five and ten and makes "how many more to ten?" something a child can see rather than compute. Teen numbers are ten and some more — the first place-value idea.
Three ways to teach it at home
- Fill the frame left to right, top row first, every time. The consistency is what makes it perceptual.
- Ask "how many more to ten?" constantly. That question is the engine of the making-ten strategy later.
- For teens, always show the full ten and the extras separately. Thirteen is ten and three, not "one-three".
