Factor Bingo
Here is a Board of numbers
The teacher gave a number board to
Imayan and Varman. Then, he asked them to pick out the factors of the numbers
36, 28 and 40 from the number board.
Imayan used different notations for
each number. He circled the factors of 36, drew triangles for the factors of 28
and drew squares for the factors of 40. But, Varman circled the factors of all
the three numbers. Whom do you think will complete the task of picking out the
factors of each number easily? Justify your answer.
