Maths: solid shapes

We looked carefully at page 104 of the NHM book and we counted the vertices of various solid shapes. Some of the solids have names that are difficult to spell so we had to take extra care. A vertex is a corner. Instead of saying vertexes, we say vertices.

Next we counted the straight edges of the solids. We had to take care not to miss any of them. Some of the solids do not have any straight edges at all.

At home please look carefully at the sheet I gave you. Join each shape to its correct name using a pencil and a ruler. After that, think carefully about the sentences at the bottom of the sheet. Write TRUE or FALSE for each one. Try to find reasons why each one is true or false. We will talk about the reasons tomorrow.
