Completing the Square. Differentiated cards. Green, yellow, orange, blue functional maths, red and black. A range of skills are tested leading into other topics such as transformations of graphs and algebraic fractions.(if needed). Answer sheet included. Use as a group activity or singular. I have printed 2 (A5 size) to a page and 4 to a page, laminate and keep. Variety of uses. Good for C1 to revise quadratic curves.
