Maths 2

Carrie has glued some cubes together to make a large solid cube with nine small cubes showing on a face.

She paints the large cube red.

How many of the original small cubes have:

1. three faces painted red: 8 because each corner has 4 squares.
2. two faces painted red: 4 in each corner
3. one face painted red: 2 in each corner
4. no faces painted red: 1 in the middle of the square.

Simon has just discovered copycats. A square is a copycat because you can put four of them together to make another square.

Simon wonders if triangles and circles are copycats. What do you think?
Yes because you can put four triangles together but you can’t do it with a circle.
