Weekend homework - Prime, Square and Triangular numbers and comets

This weekend I would like you to revise prime, square and triangular numbers. We have done work on all of these previously. The aim is to learn prime numbers to at least 30. Be confident in square numbers and square roots (the opposite) to 100. Be confident that you know what a triangular number is. Here are some links to help you:

Have a good weekend,

PS If anyone wanted to make a video about the prime numbers etc they could email it to the class email address and I will post it on the blog

A challenge for you: (from Nrich)

Try with the squares of the numbers between 4 and 20.

Did you find any square numbers which cannot be made by adding two prime numbers together?
