I think my number is 3 because I learnt using soft edge tiles (our activity) that we use the use the Problem Solving Steps: Understand the Question, Choose a strategy, Try it out and Check. In this lesson I was mostly revising on stuff I had already learnt and testing it out. I learnt how to unpack the 4 steps and locate good mathematician toolbox strategies. I will use it in other maths lessons or maths problem solving tests. It unlocked me to new ways of problem solving.
