Everyone was put to task again with one of today's challenge.
We have to create a game and the variation.
Multiply a 2-digit by a 1-digit number.
Which combination will not exceed 100?
What is the largest possible product? or
What is the lowest? Why?
While looking at all the product written on the board it was brought to our attention that
e.g. 15x 2=30, 12x5=60 having the same digit, the answers differ. Looking at it closely, we started to look for patterns or relationship between the numbers (the difference between the answers is 10 times the difference between the ones place), making generalisation.
Not only did I challenge myself to surface as many different combination as possible, this activity created plenty of joy.
