Year 5 factors starters: the 10 questions
How to use these Year 5 factors starters
First, give yourself about 30 seconds for each question. Then write the answer down before you check it. If an answer is wrong, look at the factors, multiples, primes, squares and cubes lesson again. After that, move on to the factors, multiples, primes, squares and cubes worksheet for longer questions.
Finally, repeat these starters a few days later, because regular practice makes the facts automatic. Moreover, all the pages of this chapter work together, so you can move between them at any time. For example, many pupils read the lesson on Monday, practise on Wednesday and test themselves on Friday.
