Algebraic patterns and expressions landmark activity Examples of pupils’ work

Examples are from Investigation 2, Q. 1 A B "Describe the pattern's structure and predict the expression for the total number of lights." Investigation 2, Q.1 D E "Explain how the numbers and variables in your pattern are related to the lights in the pattern"

"Describe the pattern's structure and predict the expression for the total number of lights.” (Inv 2, Q1 A B) What are the pupils noticing?

"Explain how the numbers and variables in your pattern are related to the lights in the pattern” (Inv 2, Q1 D E) How will you use the software to enable pupils to respond to this challenging question?
