OMA Answer these quick fire questions on your mini whiteboards. Learning Objective Multiply any integer by 10, 100 and 1000. Discuss the following numbers… What is the relationship between these numbers? What number is missing in the sequence? What happens when we multiply 19 by 10? It looks like we add a zero, but really all the numbers move one place along the grid to the left. Now multiply by 100…. Now multiply by 1000… YOUR TASK! Miss Newton and Mrs Byrne: Nh7 pg 35 Miss Todd: Abacus pg 6 and 5 (Q1) OMA Mental Maths Learning Objective Multiply any integer by 10, 100 and 1000 in the context of money. 12000 How can I multiply this number by 10? 100? 1000? 12000 What if I wanted to divide this number by 10? 100? 1000? 4.5 How can I multiply this number by 10? 100? 1000? 4.5 What if I wanted to divide this number by 10? 100? 1000? Now try these… YOUR TASK! Miss Newton– Nh7 pg 9 Mrs Byrne and Miss Todd– Abacus pg 7 OMA Mental Maths 27000 What if I wanted to divide this number by 10? 100? 1000? Jo’s shelf is 126cm long. She wants to put 10 boxes on this shelf. How much space will she have for each box? Henri has scored 5923 runs in cricket over 100 matches. How many runs has he scored on average in each match? Now try these… Over to you! Miss Newton: Abacus Page 7 Mrs Byrne: Nh7 pg 39 Miss Todd: 0.2 x ? x ? / ? = 0.2.Discuss. Write own calculations which begin and end in the same number. OMA Mental Maths Learning Objective Multiply using the grid method including decimals. STARTING OFF 89 x 123 X 100 20 3 80 9 First partition each number like this. Where everything goes… X 80 9 100 8000 900 20 1600 180 240 27 3 Now times where the arrows meet (where the dots are). Totalling X 100 20 3 80 9 8000 900 1600 180 240 27 = = = Now total up all the circled numbers. 8900 1780 + 267 10947 Now try these… Now for some decimals… Over to you!
