Year 5 Number: Decimals Lesson 3 25/11/2020 To be able to find complement decimals that total 1 Activity 4: Shaun says, I know that 2 + 8 = 10. So, I can use this to identify quickly that 0. 222 + 0. 888 are complements that will make 1 whole. Is Shaun correct? Explain your answer.

Year 5 Number: Decimals Lesson 3 25/11/2020 To be able to find complement decimals that total 1 Activity 4: Shaun says, I know that 2 + 8 = 10. So, I can use this to identify quickly that 0. 222 + 0. 888 are complements that will make 1 whole. Is Shaun correct? Explain your answer. Shaun is not correct. When he adds the two thousandths together they will make 10, but he will need to exchange 10 thousandths for 1 hundredth. This means that he will have more than 10 hundredths and so on. The answer is 1. 110. Specialist 1 -to-1 maths interventions and curriculum resources
