2 Welcome Jim Wilcox Primary Coordinator

3 Overview Introduction Hands on activities in groups talk, share, explore Discussion Questions Feedback

4 Icebreaker You each have a number Find: Someone whose number is either a multiple or a factor of yours Multiple the product of any number E.g. 4: 4, 8, 12, 16, Factor a number that can divide into another number E.g. 12: 1, 2, 3, 4, 6

5 Icebreaker Find: Someone whose number, added to yours, makes a prime number Prime number: has only 2 factors 1 and itself E.g. 5, 7, 11, 13

6 The basics Make it fun Games, investigations, hands-on Use your child s interests drawing, designing, reading, competitions Interactive Engage with your child Communicate Question, discuss, investigate Use available resources Household items Daily life Coordinate with classroom learning? It depends Know the limits When to stop?

7 The basics Make it fun! Let s play a game! Close Call: An Addition card game

8 Close Call: An addition card game Remove 10-K cards (keep only A-9) Shuffle 4 cards to each player Turn over Arrange cards - pairs to make 2-digit numbers Eg. 8, 6, 1, 3 rearrange to = 99 Add numbers closest to point 10 rounds

9

10 Close Call: An addition card game Remove 10-K cards (keep only A-9) Shuffle 4 cards to each player Turn over Arrange cards - pairs to make 2-digit numbers Eg. 8, 6, 1, 3 rearrange to = 99 Add numbers closest to point 10 rounds

11 Domains Number number sense and facts Counting, sorting, calculating Shape 2D and 3D shape Measurement Length, weight, volume, time Data handling Sorting, probability, graphing Problem solving In all areas

12 Number Number sense and facts Counting Ordering, comparing Sorting Patterns Calculating

13 Times 2: a multiplication game Remove Jokers Shuffle Turn over 2 cards First person to add cards and multiply by 2 takes cards Play to end of deck Player with most cards wins

14

15 Times 2: a multiplication game Remove Jokers Shuffle Turn over 2 cards First person to add cards and multiply by 2 takes cards Play to end of deck Player with most cards wins

16 Adjust activities Adjust to suit your child How might you adjust the Times 2 game? Times 4, 5, 10, etc. Use dice for multiplier Use just some of the cards E.g. 1-5 (for up to 10 x 2)

17 Estimation A very important skill Use rounding Can start at early age & develop

18 Estimation: a breakfast game How many Cheerios are in the bowl? Can you estimate? How can you check your estimate quickly? How accurate does it need to be?

19 Shape 2D and 3D shape Angles Symmetry Relation in space Patterning

20 Activity: Elastic shapes

21 Activity: Elastic shapes At least 2 people hold an elastic circle Move it around into various 2D shapes E.g. rectangle, trapezoid, equilateral triangle Discuss the shapes How do we know this is a square? How can we make an equilateral triangle? How can we make sure all sides are equal?

22 Activity: Tangrams

23 Activity: Tangrams

24 Tangrams

25 The basics: engage your child s interests Does your child like: Making things? Drawing? Singing? Reading? Investigating?

26 Shape: symmetry

27 The basics: make it interactive Engage with your child Be involved in the activities Family time Increases the fun Prompts communication

28 Measurement Length, weight, volume Measuring Non-standard units (hands, feet, blocks, ) Standard units (cm, m, g, kg, ml, L, ) Comparison Time

29 Measurement: Scavenger Hunt Find items in the room that match the measurements

30 Measurement: Time How can we make sure we get there on time? If we need to be there at 11:00 and the taxi will take 45 minutes, when will we need to leave? Read timetables: which train/plane would be the best?

31 The basics: communicate Learning through talk - powerful Connections, problem solving, memory Question Open-ended questions Discuss Debate Provoke Investigate Do measurements need to be accurate? Why? How can we measure the volume of: A stapler? A toy? What is volume? Are there some things that are easily measured? Why? How can we use this knowledge?

32 Data handling Collect, sort, present data Use data analyse, evaluate, make predictions Probability

33 Probability Game Remove face cards Shuffle cards Deal 3 cards to each player The 1 st and 3 rd card face up The middle card face down Each player predicts whether the mystery card is lower, between or higher than the showing cards If guess correctly, keep the cards Play until end of deck Winner has most cards

34 Data handling: investigation Home projects How can we reduce the amount of rubbish we throw away? How much rubbish do we throw away each week? What kinds of rubbish do we throw away? Collect, measure, record, graph, analyse, evaluate, make suggestions

35 Data handling: investigation What does this show? What can we do about it?

36 The basics: use available resources Household items Cards, coins, shapes, measuring tapes, kitchen scales, clocks, Daily life Shopping, travel, entertainment Planning, recording, discussing

37 Problem solving In every domain Number Measurement Shape Data handling Vitally important Mathematical literacy

38 A logic problem: Problem solving: puzzles

39 A logic problem: Problem solving: puzzles

40 The basics: coordinate with classroom learning? It can help Reinforce classroom learning Use new skills in context It depends Your child s interests Available resources Time

41 The basics: know the limits When should you challenge your child? When should you stop? Can it be counter-productive? You know your child best.
