1 9 7-8 5-6 3-4 1-2 Number - Calculations.
I can add and subtract three digit whole numbers using written methods. I can multiply and divide whole numbers by 10. I can multiply and divide two digit numbers by 2, 3, 4 5 or 10. When given a number sentence, I can create related sentences, e.g. If I know that 14 x 5 = 70, I also know that 5 x 14 = 70 and 70 ÷ 5 = 14 etc. I can carry out simple calculations involving negative numbers. I can add and subtract three (or more) digit numbers, including decimals, using a written method. I can multiply and divide whole numbers by 10 or 100.    I can multiply a simple decimal by a single digit. I can multiply two digit whole numbers by a single digit whole number. I can divide by a single digit number. I can multiply and divide whole numbers and decimals by 10, 100 and 1000. I can multiply and divide any three -digit number by any two-digit number. I can order, add, subtract, multiply and divide negative numbers. I can carry out multiplications and divisions involving decimal numbers. I can calculate with numbers written in standard form. These slides are printed as an A5 booklet.

2 Sum Difference Product Integer Calculate Standard Form
Key Words / Methods Never heard before? Heard of but not sure what it means? Know what it means and can explain it in context Jot down your ideas here... Sum Difference Product Integer Calculate Standard Form

3 Fluency Problem Solving Reasoning
I can multiply and divide two digit numbers by 2, 3, 4, 5 or 10 I can multiply whole numbers by 10 I can add and subtract three digit whole numbers using written methods Fluency Problem Solving Reasoning a) 68 ÷ 4 = b) 45 x 3 = c) 13 x 10 = Kelly has a jar containing 534 beads. She has 126 red beads and 209 blue beads. The rest of the beads are yellow. How many yellow beads does Kelly have? 7 x 3 = 21. Show me a division using the same three numbers

4 Billy says this is false as 100 has three digits so it should be 0.902
I can carry out simple calculations involving negative numbers I can multiply and divide whole numbers by 10 or 100 I can multiply a simple decimal by a single digit Fluency = = = Problem Solving 902 ÷ 100 = 9.02 Sarah says that this is true because the numbers have moved two places. Billy says this is false as 100 has three digits so it should be 0.902 Who is right? Reasoning Convince me that 3.8 x 3 is 11.4

5 Fluency Problem Solving Reasoning
I can add and subtract three (or more) digit numbers including decimals, using a written method I can multiply two digit whole numbers by a single digit whole number I can divide by a single digit number Fluency Show me how you would work out….. a) b) Problem Solving There are 37 Smarties in a tube of Smarties. Ben has 6 tubes of Smarties. How many Smarties does Ben have altogether? Reasoning Convince me that 324 ÷ 6 = 54

6 Fluency Problem Solving Reasoning
I can multiply and divide whole numbers and decimals by 10, 100 and 1000 I can multiply and divide any three-digit number by any two-digit number Fluency Answer these questions a) x 100 = b) ÷ 1000 = c) 3.5 x 1000 = Problem Solving Reasoning 317 people are going on a school coach trip. Each coach will hold 28 passengers. How many coaches are needed? You must show all your working out. Convince me that I have made a mistake calculating 348 x 27 300 x 20 = 6000 300 x 7 = 2100 40 x 20 = 800 8 x 7 = 56 = 8956

7 Put these numbers in order from smallest to largest
I can order, add, subtract, multiply and divide negative numbers Fluency Put these numbers in order from smallest to largest -3, -14, - 2, - 9, 4, - 18 Problem Solving The temperature in Glasgow is -10oC. The temperature in London is 5 times warmer than in Glasgow. What is the temperature in London? Show all of your working out. Reasoning Sandy says that -3 x -4 = -12 because 3 x 4 is 12 but the numbers are negative, so the answer must be negative. Is she right? Give a reason for your answer

8 How can you use this information to work out
I can carry out multiplications and divisions involving decimal numbers Fluency 23.2 x 3.4 = Problem Solving X 93 = 4278 How can you use this information to work out 0.46 x 9. 3? Reasoning True or False? 28.8 ÷ = 24 Explain your answer.

9 Give your answer in standard form.
I can calculate with numbers written in standard form Fluency Work out the value of (2.3 × 1012) ÷ (4.6 × 103) Give your answer in standard form. Problem Solving One sheet of paper is 9 × 10–3 cm thick. Mark wants to put 500 sheets of paper into a paper tray. The paper tray is 4 cm deep. Is the paper tray deep enough for 500 sheets of paper? Explain your answer. Reasoning How would you convince someone that dividing by 0.2 is the same as multiplying by 5?
