How Many Meatballs!

Here is a problem solving lesson all about the volume of spheres and cylinders! You will need a pack of meatballs a jar of pasta sauce and a pan for the pupils to use and measure. I have included teacher hints on the slides which will need deleting out before you can use it. I wish I could claim it was all my idea but I stumbled across it on Dan Meyer's blog and developed the idea into something that I could use in my classroom.
