Mouse Count 7

Counting in 2s

How many mice could it be?

Could it be 1 mouse? Why not? Is it more than one mouse? How do you know?

Could it be 50 mice? Why not?

Encourage estimation by suggesting numbers that are obviously wrong and asking learners to explain why.

Count up in 2s to 10 – use the Numicon shapes or Cuisennaire rods as you count. Link with grouping, so “how many 2s are in 10?”

Place the 2 shapes on the number line as you count in 2s.

How many 2s equal 10?

Five 2s equal 10.

Five groups of 2 eyes equal 10 eyes altogether.

How many 2s in 10? There are 5 2s in 10.

Put the 2 rods in the number track.

Or use the 10 shape or 10 rod because you know there are 10 eyes altogether.

What about this?

Make up your own problems with different numbers of eyes.

What do you notice about the numbers of eyes?

What if……….

……..you could see ears wiggling?

…….or whiskers twitching?
