This maths worksheet for Year 5 children introduces the idea of ‘index’ for writing the square of a number. Children should understand that 42 means ‘4 squared’ or 4 times 4. Often it is mistaken for 4 x 2.
Remind children that ‘square numbers’ are called ‘square numbers because they can be represented in an array with an equal number in both rows and columns. Again, encourage children to learn their square numbers up to at least 10 squared. This will help greatly when square roots are introduced.
