Challenge 3: Pollution

Just like Planet Earth, Turasmara has a lot of pollution in its ocean. This is the result of too many plastic items being used and thrown away.

Your mission is to help clear the ocean - by following the instructions below.

To clear the ocean you must pick 2 numbers from the ocean floor (smaller might be better). Multiply the two numbers together and if the PRODUCT (answer) is also on the ocean floor ALL 3 numbers can be removed.

An example of this might be to pick 6 and 2.

6 x 2 = 12

The numbers 6, 2 and 12 are all in the ocean so they can all be removed.

Why not make the game and play with a partner?

Copy the numbers onto big sheets of paper and place them on the floor.

Then get 3 small objects to throw, for example beanbags.

Take it in turns to throw the objects. If you can get the objects you throw to land on 3 numbers that make a PRODUCT calculation (for example 2, 6 & 12) then you can remove these numbers from the ocean. If not, they stay where they are and your partner takes a turn.

The winner is the person who removes most pollution from the ocean.
