Maths Workshop Addition and Subtraction Year 3-4 1 + 2 + 34 - 5 + 67 - 8 + 9 = 100 Using only – and + can you find another way to make 100 using the digits 1 to 9 in the correct order

Solution… 1 + 2 + 34 - 5 + 67 - 8 + 9 = 100 12 + 3 - 4 + 5 + 67 + 8 + 9 = 100 123 - 4 - 5 - 6 - 7 + 8 - 9 = 100 123 + 4 - 5 + 67 - 89 = 100 123 + 45 - 67 + 8 - 9 = 100 123 - 45 - 67 + 89 = 100 12 - 3 - 4 + 5 - 6 + 7 + 89 = 100 12 + 3 + 4 + 5 - 6 - 7 + 89 = 100 1 + 23 - 4 + 5 + 6 + 78 - 9 = 100 1 + 23 - 4 + 56 + 7 + 8 + 9 = 100 1 + 2 + 3 - 4 + 5 + 6 + 78 + 9 = 100

What’s the plan? Overview of changes in maths curriculum What your child will be learning in class Supporting your child at home

Changes in the Maths Curriculum When we were younger = practising methods But, methods without understanding = errors 5 years old and I already hate maths

Changes in the Maths Curriculum New curriculum = methods + understanding Methods (procedural fluency) Understanding (conceptual understanding) These must be taught: in parallel with manipulatives at the right stage Raised expectations Tutor Warning

Changes in the Maths Curriculum

Changes in the Maths Curriculum Child led learning - layers Hundreds tens and ones NOT hundreds tens and units! MUST use manipulatives in Y3 and Y4 ‘Regrouping’ not ‘borrowing’ or ‘exchanging’

Changes in the Maths Curriculum

Base 10 Vs Place Value Counters Base 10 gives more of a concept of size Children do just get PV counters

Subtraction Note that the number line method should still be modelled as part of a mental maths strategy When calculating with time and finding time differences, the numberline method should be used EVERY TIME.

Supporting your child at home Play games Homework – Praise. Don’t panic! Ask your child to explain everything

Supporting your child at home Stuck in the Mud Roll 5 dice. If 2 or 5 is rolled, discard the 2s and 5s and roll remaining dice. Repeat until there are no 2s or 5s rolled. Add up these dice and add this to your score 5 rounds. Highest score at the end wins.

Supporting your child at home Tug of War Start at 25. Take it in turns to roll the dice. One player will add their score to 25, the other will take it away from 25. The person subtracting wants to get to 0. The ‘adder’ wants to get to 50. Repeat until the score reaches 0 or 50.

Supporting your child at home Card games and counting games (e.g. Snakes & Ladders, Ludo and any dice games) Recognising numbers and sequences when out and about (e.g. house numbers-odds and evens, bus numbers, car number plates etc.) Recognising shapes (e.g. buildings, windows, food packaging etc.) Helping in the kitchen (e.g. weighing ingredients, time duration, volume of liquids etc.)

Supporting your child at home Helping in the supermarket (e.g. paying and change, weighed fruit and vegetables, calculating better value etc.) CDs/Games for learning times tables Take and compare measurements when DIY shopping (e.g. measuring spaces for curtains, furniture, wall paper etc.) Tell the time/use timetables (e.g. bus times Sky TV guide)
