Subtraction using the Short Bead Stair

How we do subtraction with the Short Bead Stair

In this activity, the child learns how to do subtraction with the Short Bead Stair and the Series one sum card for subtraction. The directress begins by asking the child to build the short bead stair on the piece of felt, that is placed at the top of the mat.

The directress then shows the child the sum card and reminds him what subtraction means, she tells him that when we do subtraction, we take the smaller number away from the bigger number to get an answer. She points to the first sum on the card, (4-3=) The directress brings the number 4-bead forward and reminds the child that we need to take 2 away from 4. She shows the child how to cover up two of the beads and asks him to count how many are left, the child should count two, and say “two”.

The child is encouraged to continue in the same manner until all of the sums on the card have been completed.
