How Much is that Number Worth?

Today we did some revision on place value. The children have been working on identifying how much an actual number is worth and how this is made up.

To help us we played a game where we rolled the tens dice and the ones dice to create a two digit number.


The challenge was to make the number up using bundles of ten and then make the remaining ones.
It was a bit tricky managing the rubber bands but we did it. Our partner checked our number of tens and ones to make sure we were correct.

This activity encouraged us to see that ten ones are the same as a bundle of ten.
So we could make the connection between our models and how they are represented, we recorded what we did in symbols and words too!






Once we know this super well, we can solve larger number problems like...
54 + 32 by adding the tens: 50 + 30 = 80,  then the ones: 4 + 2 = 6 
80 + 6 = 86!
