The story of 7
We were learning how to calculate the story of 7 this week. We use cubes and sets to help us.
To start we count out 7 cubes and put them all in the right hand side set.
To write this as a sum we say: 0+7=7
Then we move one cube from the right to the left handside. To write this as a sum we say: 1+6=7.
Then move another cube from the right to the left. This is 2+5=7. We keep moving one cube at a time until we have our last sum 7+0=7.
This way we are sure we have not forgotten any combination in the story of 7.
We will be starting the story of 8 at the end of February.
