- Have your students draw a 64cm x 37cm rectangle on paper. They need to be sure that the corners are square.
- Then your students will use base-10 blocks to fill in the rectangle.
- They will begin with the flats (10x10) in the left hand bottom corner. They will put as many of these blocks as possible into the rectangle.
- They will then work with the 10s to fill up the rest of the space until they cannot fit any more.
- Then they will fill the remainder of the space with the unit blocks.
- Your students will then need to add up the total. In order to do this, they should add up each section separately. Using a simple place-value chart helps them keep track of the blocks and sums. This is how the chart should look when they are done.
