Always, Sometimes or Never? KS1

Age 5 to 7

Challenge Level Yellow star

Are the following statements about number always true, sometimes true or never true?
How do you know?

Can you find examples or counter-examples for each one?

For the 'sometimes' cards can you explain when they are true? Or rewrite them so that they are always true or never true?

When you add two numbers you can change the order and the answer will be the same	If you add 10 and take away 1, it is the same as adding 9
When you add 10 to a number, the answer is a multiple of 10	When you subtract one number from another number you can change the order and the answer will be the same

What about these statements about shapes?

If you put two squares together you get a rectangle	3D shapes have more than four faces
When you cut a square in half you get a triangle	Four sided shapes are called squares
Three sided shapes are called triangles

You could cut out each set of statement cards and arrange them in this grid.

Alternatively, you could use these interactivities to organise your thinking:
