Rela$ng Earlier Learning to Money Equivalence -­‐ connec$ng coins with Numicon Shapes Using only the 10, 5, 2, & 1 shapes: •  How many different ways can you make 2, 3, 4? •  How many different ways can you make 5? •  Calculate how many different ways can you make 10? •  Repeat the ac$vity with coins on the Numicon shapes Calculate how many £1

Rela$ng Division and Frac$ons Time   Coun$ng in 5s to 60   Coun$ng in 5s to 55 How many 5s equal 10
1 half of 10 = 5
How many 2s equal 10
1 fifth of 10 = 2
How many 5s equal 30 = 6
1 sixth of 30 = 5

What frac$on does the grey 1 shape represent? What do you no$ce about the shapes? What does this shape represent?
