What is a square to you? Have you ever really looked at squared numbers?
I was once teaching students about multiplication using grid paper. We create 2x8, 3x8 and many more to help students understand their times' tables with a display. When we realised the 2x2, 3x3 and 4x4 (yes, I did know they were called squared numbers), students kept coming and saying, 'this one is a square'. And I knew I had to use this student-created realisation and build on it for them.
Teaching Year 7 and 8 students who again know about squares but didn't know about the 'power of' was an opportunity to bring this back to life. Especially when we also had to look into square roots, the opposite of squares.
