Present the children with a range of models of square numbers (e.g. 4, 9, 16, etc). Ensure that the children can clearly see the squares which are formed.
Can you describe the patterns?
Invite children to investigate which other numbers below 100 would form square patterns.
Elicit ideas from the children.
Invite children to listen to Square Number Song. Ask them questions regarding the content of the lyrics (e.g. Which square numbers does the song mention? Which square numbers are multiples of 9? Which square numbers are even?)
Play the song again and invite the children to join in with the singing to reinforce key ideas.
It may be useful to play the song intermittently throughout the term in order to continually remind pupils of the concept of square numbers.
