encourage learners to make jottings as they work and to recognise how these can support their thinking; model this process for them and distinguish between a presentation and a jotting. Learners should not be exposed to standard written methods until they have had appropriate experience of using mental strategies. Premature exposure to working forms restricts learners’ ability and desire to use mental strategies. Inverclyde Secondary Attainment Challenge Team (Numeracy)
Inverclyde Secondary Attainment Challenge Team (Numeracy) If the top line represents amount of memory space for learning then if you memorise the steps it will always take that amount of memory space. Triangle shows that if you understand then the memory space can be compressed and you can fit more new learning in. Inverclyde Secondary Attainment Challenge Team (Numeracy)

of 2149 2 7 Inverclyde Secondary Attainment Challenge Team (Numeracy) Try this one – pupils split into 2100 and 49 which means each box in the bar has a 300 and a 7. Taking two boxes gives 300 + 300 + 7 + 7 = 614. Another one tried in class was 1/7 of 7126 which was split to 7000 + 100 + 26. 7000 gave the pupils a 1000 BUT they then split the 100 up again into 70 and 30. the 70 gave them a 10, the 26 went with the remaining 30 to get 56 and then an 8. 1/7 of 7126 = 1000 + 10 + 8 = 1018 Inverclyde Secondary Attainment Challenge Team (Numeracy)

Asked the pupil what 6 times facts did they know . . . 6 x 5 = 30 so drew that in the box, 24 left over 6 times what makes 24 – did not know What other 6 times facts do you know? 6 x 2 = 12 and then lightbulb that two 12s make 24 So bar contains a 30 and a 12 and a 12 Outside the bar is a 5 and a 2 and a 2 so 54 ÷ 6 = 9 Inverclyde Secondary Attainment Challenge Team (Numeracy)

If 1 of them is 16 then double gives 2 -> 32. If 1 -> 16 then 10 gives gives 10 -> 32 etc. Now do repeated subtraction e.g. can fit 20 of them into 720 so 720 – 320 leaves 400. Can fit 20 of them into 400 so 400 – 320 leaves 80. If 10 gives 160 then 5 must be half of that so total amount we used was 20 + 20 +5 = 45! 720 ÷16 = 45.
