so that the remaining 9 unit-blocks from each pillar can be divided equally among the three
children.

99 blocks 99 blocks 99 blocks Five 9 blocks 4 unit blocks

Now, besides the 3 unit blocks removed from the towers and the 5 unit blocks removed from the
pillars, we have 4 individual unit blocks adding up to a total of 12 (i.e., 3 + 5 + 4) unit blocks.

Can we distribute these 12 unit blocks among the 3 children?
Since the answer is yes, therefore, the number 354 is divisible by 3..

Similarly, we can learn the logic behind divisibility rules through other numbers.

MATHS LAB ACTIVITY (WORKSHEET)

Objective: Learning about prime and composite numbers.

Material required: A pencil

Directions: The Juggly Jumpers have a strange characteristic, i.e., they can jump or hop a length
equal to their value. For example, the 4-Juggly Jumper jumps 4 spaces each time. They all begin
at 0 as shown below.

0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25

Complete the chart given below. Carefully observe where each Juggly Jumper will land. The
landing positions of 1-Juggly Jumper, 2-Juggly Jumper and 3-Juggly Jumper have been filled.
