This activity is a primer for being able to read tables. I have planned a few activities where we will do addition and multiplication tables. The activity was taken from Math from Three to Seven.
Supplies/Preparation: You will need 16 cut-out shapes and can enlist your child to help with the preparation - 4 squares, one in each of these colors: red, yellow, green, blue - 4 circles, one in each of these colors: red, yellow, green, blue - 4 triangles, one in each of these colors: red, yellow, green, blue - 4 semicircles, one in each of these colors: red, yellow, green, blue What to do: Draw a 4x4 table (each cell should be big enough to fit one of the cut-out shape) with rows labeled by shapes (square, triangles, circles, semicircles) and the column labeled with colors. Ask your child to put each object into the right cell.
What to do: Arrange different sequences made of triangle, square, circle (i.e. construct permutations) and record on a sheet of paper the number of different ones. Repeat with four shapes.
A boy has as many sisters as brothers, but each sister has only half as many sisters as brothers. How many brothers and sisters are there in the family?
