This is a great starter for lessons on set of numbers and involves learners developing high level thinking and problem solving skills. I have attached a worksheet that you could use so that learners can spend more time on solving the problem and less time drawing it. Mathematics Starter Cycling Squares Square Numbers Watch [...]
