Presentation:
In order to show the child how to use the materials, the teacher presents a few short exercises. A blue strip is chosen at random. The child identifies the strip. It is placed along the top row of squares. The teacher takes a pink strip. I am going to add 5 (pink) to this 7 (blue). The pink strip is lain on the board. We can see that 7 plus 5 is 12. I read 12 here at the top, pointing to the top row of numerals. The exercises continues like this.
Then the child adds keeping the first addend the same. The second addends are chosen at random order. In these exercises the blue strip remains on the board throughout.
