  1. Numeracy Workshop 16th November 2011

  2. Aims of the workshop... • To understand how your child learns numeracy in school (focusing on the 4 calculations) • To understand how you can help your child with numeracy at home.

  3. What should my child be able to do by the end of Lower School? • Number • Shape, space and measure • Handling data • Problem solving

  4. Mental Warm Up : 10 minutes E.g.: Bingo, game, counting stick, interactive activity Main Teaching : 20 minutes Activities and challenge : 20 – 25 minutes Plenary : 5-10 minutes A Typical Maths Lesson

  5. A Typical Mental Warm Up... Bingo!

  6. Teaching Calculation • Lies at the heart of numeracy • Mental method is emphasised • - Remembering number facts • - Using them to work out new facts • - Understanding the relationship between ‘the 4 rules’ • - Repertoire of mental strategies. • Written methods follow on • Application to real life e.g.: problem solving

  7. Support Resources 100 square Multiplication Square Number lines Whiteboard & Pen Multi Link Blocks Base ten - HTU

  8. Use a number line to count, putting the biggest number first Addition Know and use number bonds to 10 and 20 2 + 8 = 10 20 + 80 = 100 200 + 800 = 1000 22 + 8 = 30

  9. Add 2 numbers that bridge 10 Add to the next 10 and then add the extra Adding 2 2-digit numbers (without bridging) 15 + 13 = + 10 + 3 Addition

  10. Addition Add two 2 digit numbers (informal method) 48 + 36 = Use a number line… Partition into tens and units

  11. Standard Written Method 48 + 36 = Expanded Written Method 48 + 36 = • T U • + 8 • 30 + 6 • 80 + 4 • 10 TU 48 +36 84 1 Addition

  12. Subtract single digit numbers, bridging through the 10 Subtraction Know by heart subtraction facts for numbers up to 10 and 20 20 = 12 + 8 20 – 8 = 12 20 – 12 = 8

  13. Begin to find the difference by counting up from the smallest number Subtraction

  14. Subtraction

  15. Subtraction

  16. Subtraction

  17. Subtraction

  18. T U 40 + 3 - 20 + 7 30 10+ 6 Subtraction 43 – 27 = The Standard Written Method The Expanded Method 10 +

  19. Multiplication

  20. Multiplication Understand multiplication as repeated addition

  21. Multiplication Understand multiplication as an array

  22. Use place value to support the multiplication of TU and U alongside the grid method Multiply multiples of 10 by units Multiplication

  23. Division Understand division as sharing 15  5 = 3 15 SHARED between 5

  24. Division Understand division as sharing

  25. Division Use known multiplication facts to work out division facts

  26. Division Reinforce division as grouping through the use of arrays and as repeated subtraction

  27. Division Divide with remainders 15 4 = 15 4 = 3 r 3

  28. Division Division by chunking 87 7 = 12 r 3 87 (10x7) • 70 • 17 • 14 • 3 (2 x 7)

  29. Shape, Space and Measure • Practical experience • Everyday / real world examples • Grasping the vocabulary • Making links e.g.: between units

  30. Telling the Time • Counting in 5s • Understanding quarters and halves • ‘0 clock, half past, quarter past, quarter 2. • 5 minute intervals • 1 minute intervals • Constant links between analogue and digital. • Reading timetables • Practice!!!

  31. RM Maths • Computer based tutoring program • Personalised Maths support • Tailored to individual needs • Gives teacher’s insights into problem areas • Consolidate skills and build confidence • Interactive and fun!
