Topic- Fun With Numbers Jumping Animals
Gabru, Bunny and Tarru are jumping all the way. Gabru jumps on every 7th square, it means he is taking 7- 7 steps. Bunny jumps on 5th square, it means he is moving 5 steps forward to reach the next square. Tarru is taking 4 steps to move forward. Gabru starts jumping from square number 90 Bunny starts jumping from square number 99 Tarru starts jumping from square number 106 a) Gabru and Bunny both jump on squares – 104, 139 and 174
First we will count Gabru’s step from number- 90 and as we know he is moving 7 steps forward we will add 7 in each number to move forward. +7 90
