CBSE Book Class 6 Maths Activity 1

(a) To verify that addition is commutative for whole numbers, by paper cutting and pasting.

(b) To verify that multiplication is commutative for whole numbers, by paper cutting and pasting

Learning Objective : To understand that addition as well as multiplication are commutative for whole numbers.

Pre requisite : (i) Knowledge of addition and multiplication of whole numbers.

(ii) Knowledge of commutative property of whole numbers.

Materials required : Grid papers, a pair of scissors and glue

Procedure (a) : (a) To verify 3 + 4 = 4 + 3

Step 1. Cut out two strips each of length 3 units from a grid paper and shade them with any colour (say Red) Fig. 1(a).

Step 2. Cut two strips each of length 4 units from a grid paper and shade them with different colour (say Blue ) Fig. 1(b).

Step 3. For representing 3 + 4, paste one strip of length 3 units and then paste another strip of length 4 units in the same line on the grid paper without

leaving any gap Fig. 1(c).

Step 4. For representing 4 + 3, paste one strip of length 4 units and then paste another strip of length 3 units in the same on the same grid paper line

without leaving any gap Fig. 1(d).

Step 5. Now, compare (by counting number of boxes) the length of strips obtained in Step 3 and Step 4.

Step 6. Repeat the activity for some more pairs of whole numbers and write your result.

Observations:

Number of shaded boxes in the presentation of 3 + 4 = …………….

Number of shaded boxes in the presentation of 4 + 3 = …………….
