Look at this empty egg box from the shop. It holds 12 eggs. Is 12 more than ten fingers? How do you know?
Look at these ten-frames. Each one shows a full ten. The extras (the counters past the full ten) are different on each frame. Read each one as ten and ___.
On the last frame, say how many more than ten before we name it.
Build a full ten first. Then add the extras.
We'll try eleven: say ten and one, then build it.
Next, twelve: say ten and two, then build it.
Then eleven again, then twelve again. Each time, say ten and ___ before we check.
Build eleven or twelve
Here is our egg box again. It has two rows of six cups.
In your maths copy:
- Draw the egg box with an egg in every cup: two rows of six small circles.
- Draw a ring around ten eggs: five on the top row and five on the bottom row, like a full ten-frame.
- How many eggs are outside the ring? Write 12 under your egg box and say: ten and two.
- Cross out one egg outside the ring. How many eggs are left? Write 11 and say: ten and one.
