I covered the paper rolls with colourful construction papers and paste magnetic tape on one side. You can use blue tack or normal tape, too.
It is a fun way to learn about colours, I must say. Especially if you have a lot of toilet rolls at home and do not know what to do with them.
Oh yes, you need to place few bowls below the tubes to catch the balls.
We’ve planned do another simple activity for colour recognition in the next few days. Stay tuned =)
