LO To assess your understanding of Pythagoras’ Theorem RAG Key Words: Reflect, Communicate, Explain, Justify 20 -Feb-21 Starter Activity Complete the ‘Heard the Word Grid. ’ Are there any key words that you have learnt or have a better understanding of now than you did at the start of this unit of work?

Grade F E D C B Pythagoras’ Theorem A I can recognise square numbers and cube numbers. I can find the value of squares and cubes and I can calculate square roots. I can solve problems involving square numbers, square roots and cube numbers giving reasons for my answers. I can find the length of the hypotenuse in a right angled triangle using Pythagoras Theorem. I can find the length of a shorter side in a right angled triangle using Pythagoras Theorem. I can find I can solve 3 D missing lengths Pythagoras and distances in problems. shapes other than right angled triangles using Pythagoras Theorem.
