  1. How to Help Your Child with Maths INSPIRE 6ZC

  2. This morning? “They do it all differently these days!” Bridging the gap They are teaching you this morning!

  3. What is important? • A strong foundation in the basics • Just like the foundations of a house, if the basics aren’t solid then cracks will appear • So, keep returning to the fundamentals • Your child should not just be familiar with the basics, but fluent • Don’t be afraid to do the old drills and skills

  4. Anything else important? • Multiplication tables • Rapid and accurate addition and subtraction • Telling the time, analogue and digital • Drip, drip, drip….

  5. Anything else important? • A sound understanding of place value is very important Not millions Th H T U . 1/10 1/100

  6. So what are the basics? • Addition • Subtraction • Multiplication • Division • Problem solving

  7. Some practical ideas… Times tables in the car…drill and quickfire Real life, Do I have enough money? What change should I get? Which is the best value? What time will it be in 25 minutes? Cooking, weighing, measuring. Do I have enough rice to make this dish?

  8. What methods do we use? • Mental first! • To equip children for real life, their mental maths skills are the most important. • Speeding up the accuracy and fluency of mental methods will help with written methods later.

  9. What methods do we use? • Mental strategies ( a small selection) • Bonds to 10 and 100 • Partitioning. 24 + 43 = 20 + 40 = 60 4 + 3 = 7 60 + 7 = 67

  10. What methods do we use? Your turn…. • Play I say, you say with your bonds to 10, then 100. then…. • Solve this calculation by partitioning… • 54 + 32 = • If you finish early, you can practice by using the number cards on your desks, turn over 2.

  11. What methods do we use? • But they will soon use more written methods in their Mathematics • Using a variety of methods • Building towards a standard method • They often follow the path from an expanded method to a shorter method and finally a compact method

  12. Addition in Key Stage 2 • The Compact Method 75 +23 98

  13. Addition in Key Stage 2 • Carrying • The Compact Method 78 +23 Notice the carry written 101 under the line

  14. Addition in Key Stage 2 Your turn…. Solve this calculation 65 + 78

  15. Addition in Key Stage 2 • Decimals “Decimals Don’t Dance!” • The decimal point stays in the same place 71.3 71.3 2.25  2.25  Decimals should not be written in the square of a book as they have no place value. They should be written on a line 1 2.4

  16. Addition in Key Stage 2 Your turn…. Line up the decimals to solve this calculation using the compact method 43.2 + 12.25 =

  17. Preparing for Multiplication • Children must know their tables - fluently • ? X 5 = 15 • 3 x ? = 15 • 3 x 5 = ? • Mad Minutes….your turn!

  18. Preparing for Multiplication • Place value Th H T U 1/10 1/100 • Multiplying by 10 Move each digit one place to H T U That leaves the left (remember MultipLication) 1 7 a space in 1 7 to which we put a zero to hold the place

  19. Preparing for Multiplication • Common Errors • Why don’t we say ‘add a zero’ when multiplying by 10? • 1.7 x 10 = 1.70 we have added a zero but have not made any difference to the number • Why do we need a zero at all? • This is 170 without a zero H T U which looks like 1 7 17

  20. Multiplication in KS2 • Grid Method 19 x 6 10 9 60 6 60 54 + 54 114

  21. Multiplication in KS2 • Grid Method 29 x 6 20 9 6 120 Knowing 2 x 6 = 12 is a basic fact So 20 x 6 = 120 can be ‘grown’ from this basic fact

  22. Multiplication in KS2 • Grid Method 27 x 23 20 3 20 400 60 400 7 140 21 140 2x2=4 + 60 20x2=40 21 20 x20 = 400 621

  23. Multiplication in KS2 Grid method Your turn…. 22 x 14 =

  24. Multiplication in KS2 • Shorter Vertical Method 19 write this first x 6 60 (10 x 6) 54 (9 x 6) 114

  25. Division in KS2 • Tables! Tables! Tables! • How to rally robin Your turn: try it with 2, 5 and 10 x tables.

  26. Division in KS2 • Tables! Tables! Tables! • Chunking Method 43 ÷ 7 is written as 7 43

  27. Division in KS2 7 43 -14 2 X 7 Keep it simple 29 -14 2 X 7 Use 1,2,5,10 times tables for multiples of 7 and so on

  28. Division in KS2 13 r 2 7 93 -70 10 X 7 23 Can we get 10 x 7s, 5 x 7s? No -14 2 X 7 9 - 7 1 X 7 2

  29. Division in KS2 Chunking method Your turn 78 Remember we are taking away, lots of 5…. 5

  30. Stand up bingo Write any 5 of the following numbers on your boards. 0, 2, 4, 5, 6, 8, 10, 12, 14, 15, 20, 22, 24, 26, 28, 30
