Operations with the Abacus: Static multiplication (without change)

How is static multiplication done using the Abacus?

In this activity, the child learns how to multiply using the abacus and recording the answers on the expanded notation cards with the correct coloured markers. The directress begins the activity by placing the expanded notation card in front of the child and reading through the operation with him read (2343 x 2)

The directress then reminds the child of the (x) sign and tells him that they need to multiply the number twice. She reminds the child that they need to take 3 twice as they are multiplying by 2. The child brings forward 3 unit beads, she then leaves a space and brings forward another 3 unit beads. He counts and records 6 in the units column.

The child is encouraged to continue in the same manner with the tens, hundreds, and thousands. The directress reminds the child to record the answers in the correct column with the correct coloured marker. Once the operation is complete, the directress shows the child how to check the answers.

This is a great activity to reinforce multiplication using other materials.
