Addition Mental Maths Learning Objective I am able to count in 2’s, 5’s, 7s, 10s, and ½’s Mental Maths Learning Objective I am able to count in 2’s, 5’s, 7s, 10s, and ½’s Main Learning Objective By the end of this lesson, I will know:That addition can be done by adding using either number first. I will also know how to solve missing number problems Addition • What is 5 + 3? What is 3 + 5? Which number to start with? What is 4 + 3? What is 3 + 4? It Does not matter which number you add first • This means addition in commutative What is the solution to this problem? 11 + -------- = 17 What is the solution to this problem? 100 + -------- = 255 What is the solution to this problem? 134 + -------- = 155 Main Learning Objective I know:That addition can be done by adding using either number first. I also know how to solve missing number problems. Plenary • In this lesson we learnt • How to count in 2s, 5s, 7s, 10s and ½ s • How to add. Which is bigger? 55 + 5 = or 5 + 55 = ? They are the same! Both make 55. More Addition • What is 5 + 6 + 7 make? • What does 7 + 5 + 6 make? You can add more than 2 numbers together.
