1 - Getting Started ~3 mins
A picture shows a heap of lolly sticks. Counting them one by one would take all day.
Could bundles help us? Ten sticks are already tied with an elastic band into one tidy bundle, with a few loose sticks still beside it.
2 - Watch and Notice ~8 mins
Remember the tidy bundle of ten sticks? A ten-rod is the same idea: one tidy ten on our mat.
Units are the loose ones left on their own. Our mat has a tens place and a units place.
Here are ten loose units still in the units place. Next, the same ten as one tidy ten-rod. Same amount; tidier count.
Say how many tens and how many units you see before we name the total.
3 - Try It Together ~8 mins
Today we explore: build a number from 10 to 19 on the place-value mat with tens and units columns.
Gather ten loose units, then trade them for one ten-rod. Add any extra units beside it. We will try 11, then 14, then 16, then 18.
Build and trade within 19
4 - Draw the Rod and Units ~3 mins
In your maths copy, draw one ten-rod and three units. Write 13 beside them.
5 - Class Challenge ~8 mins
Today we work through these numbers together: 10 → 12 → 15 → 19. Trade ten units for a rod, then add the extras.
The class says each one as one ten and ___. Then we all look at the board build and agree before the next number.
Trade and build
