Monday Challenge: 6th July

Three Ball Line Up

Two children are playing with three balls, one blue, one red and one green.

They toss up the balls, which run down a slope so that they land in a row of three.

In how many different ways could the balls land?

Can you use and apply a systematic way of working to ensure that you find all the possible solutions?

Extension: What would happen if you added a Yellow ball as well?

Would this increase or decrease the number of possible ball arrangements? Prove it!

How many more/less? Prove it!
