Objective: To reinforce the concept of the distributive property of multiplication
over addition.

Materials Required: Grid paper, some colourful bindis and a sticking tape.

Procedure:

Š Divide the class into pairs.

Š Tell the students to take grid paper.

Š Ask one student in each pair to put some red bindis to show 3 × 5 on the
grid paper.

Š Ask the partner to put some green bindis to show 3 × 4 on the grid paper.

Š Ask them to count the number of bindis put on the grid paper.

Student 1: 3 × 5 = 15 Student 2: 3 × 4 = 12

Total = 15 + 12 = 27

Š Now, ask them to join both grids using sticking tape as shown below and
observe the arrangement.

Š Count the total number of bindis.

3 × (5 + 4) = 3 × 9 = 27

Ask what they observe.

From the above presentation, we can see 3 × 5 + 3 × 4 = 3 × (5 + 4)
27 27
or 3 × (5 + 4) = 3 × 5 + 3 × 4

Š Repeat the above activity by taking different numbers of columns and rows
of the grid.
