A bun tray holds ten. Eight buns sit in the tray and five wait on the plate. How could we make the tray easy to count at a glance?
Our bun tray is a ten-frame: ten spaces ready to fill. Filling the empty tray spaces is the same move as filling the frame.
When a total goes past ten, the frame is not enough on its own. First look at the starting number on the frame. Count the empty spaces: that is how many we still need to fill the ten. Then read the leftover as ten and some more.
9 + 3: how many empty spaces to fill the ten?
8 + 5: how many empty spaces to fill the ten?
7 + 4: how many empty spaces to fill the ten?
Now you are bakers. Work with your partner. Your ten frame is the bun tray, and your plate is beside it.
Put the bigger number of buns in the tray and the smaller number on the plate. Move buns from the plate into the tray, one at a time, until the tray is full. Then say ten and ___ for the buns still on the plate. Take turns to move the buns.
- 9 + 4
- 8 + 6
- 7 + 6
- 5 + 8
Fill the ten first
In your maths copy, write these carefully:
- 8 + 5 = 13
- 9 + 3 = 12
