This time with rice grain I wanted to show them how the mound of rice of a bigger number is bigger than the mound of rice in a smaller numbers.
On a whiteboard I write the numbers and later ask the boys to scoop with the frequency of the numbers on the board. Like 2,3 or 4 scoop.
Now they can see the significance of how the number 5 mound are bigger.
We run out of rice grain at no 7. But well I have gotten the lesson across.
