Following your visit to the Space Centre last week, you will be designing and making your own rocket so don ’t forget to bring in an empty 2 litre bottle.
We will also be continuing to use calculators to solve number puzzles.
Click on this activity to help you to find all the prime numbers less than 100.
Now try to solve this puzzle-
Can you make any square number by adding two prime numbers together?
eg. 4 = 2 + 2
9 = 2 + 7
16 = 5 + 11
So far so good! But can you carry on?
