Part-whole thinking in maths week 8 Term 2 09

Today this group was working at problem solving.
Story problem
Today 24 children were going to the library and they were able to choose 4 books each. How many books altogether?
If you look at the our pictures you will see that we are using the towers of ten.
First step imaging
What does 24 look like using our Tower of ten.... Can we image what 2 groups would look like....what 3 groups would like.....?
We needed to visualise what this looked like, so we understood how we could group numbers.
The next step we had to think about was to see these numbers as a mutliplication problem. We are learning how to split tens and ones. This is called part-whole thinking. We are learning how to see problems using different strategies.
We can solve a problem using our number knowledge.
eg 24x1+ , 24x2=, 24x3=, 24x4= We know that 20x4 plus 4x4 can be a way to solve our problem
or if we know that 24x2= 48 we can double the number
Gerry is showing the group how he solved the problem. Tom and William are showing the group how they solved the problem. We are buiding up flexibility in our thinking.
