Plan: Plan for Year 6 Weekly Plan: Week 1 Block A1.a: Multiply integers and decimals by 10, 100 or 1000 Block A1.b: Divide integers by 10, 100 or 1000, and divide decimals by 10 or 100 Day 1 2 3 Mental oral starter Count on or back in 6s, 7s, 8s, 9s to/from about 100. 3 teams count in multiples of a given number. Eg teacher says 6, a ch in 1st team responds 12. Next ch in team says next multiple, … Each team gets a turn with nos 6–9. If a ch gets it wrong they kneel down and another ch in team carries on. Multiply by 8 by multiplying by 2, doubling, then doubling again. Fill 6 × 2 grid with multiples of 8 between 24 and 360. Cover those with Post-it notes with the numbers being multiplied by 8 (3–45). Chn work to fill in their grids by multiplying the Post-it note numbers by 8 (2 × 2 × 2). Reveal answers! Know addition pairs that total 100. Pairs write 5 numbers from 1–10. Select a 10–99 card & read out, eg 26. Chn say how many more to 100, eg 74. Pairs with numbers matching digits from the answer score place value of that digit, eg if they have 4 they score 1, if 7 they score 10. Objectives Main teaching * [Y6] Multiply any integer by 10, 100 or 1000 and understand the effect Write 26, 260, 26 000 on board. What is the relation between them? Use p/v grid to explain how numbers [Y6] A1.a.1 are made of digits that occupy places according to value. Discuss [Y6] Recognise that what happens if multiply by 10. It multiplying by 100 is looks as if we add a 0 because all equivalent to the digits have moved along 1 place multiplying by 10, then to the left. Multiply by 100/1000. [ITR A1.a] by 10 again [Y6] Multiply decimal numbers by 10, 100 or 1000 [Y6] Divide any integer by 10, 100 or 1000, and understand the effect [Y6] Recognise that dividing by 100 is equivalent to dividing by 10, then by 10 again [Y6] Divide decimal numbers by 10 or 100 Use p/v grid with H, T, U, t, h. Demo multiplying £3.46 by 100. Write £3.46 [Y6] 6.1 p3 on p/v grid and fill in answer (move each digit 2 places to left = £346). Record the ×. Rpt for £12.83 × 1000. Put £2.89 × 10 on board and 3 possible answers. Chn pick one and show on grid. Rpt for £9.10 × 100. Demo that dividing 12000 by 10, 100 or 1000 is the reverse of [Y6] A1.b.1 multiplying by 10, 100… This time the digits all move 1/2/3 places to the right. Show that dividing by 100 [Y6] 1.1 or 1000 is the same as dividing by 10 twice or three times.

First child writes Recognise the number divided by relationship 100. They check each between division other’s answers. and multiplication. Know that dividing by 100 is the same as dividing twice by 10. Day 4 5 Mental oral starter Objectives Main teaching * Read the time to 1 minute on a 24-hour clock. Draw 5 analogue clocks on board: 3:10, 7:40, 12:30, 1:55, 6:35. Write these digital times: 13:55, 06:35, 03:10, 19:40, 08:20, 15:10, 01:55, 00:30, 18:35, 02:05, 07:40, 12:30. Pairs match digital to analogue times & pick out 2 odd digital times. Discuss. Jo’s shelf is 126 cm. How much space each for 10 boxes? Remind chn how to divide by 10 using p/v grid. We move digits 1 place to right. Write the calculation and perform it using the grid. 126 ÷ 10 = 12.6. Jo has 12.6 cm for each box. Demo 5923 ÷ 100 (move digits 2 places to right). Discuss rounding answer down. Rpt for 294.3 ÷ 10. Count on/back from any number in steps of 19 or 21. Chn in pairs. Divide class in half. Half count in 21s; other half count in 19s. Write start number, eg 245. Each ch writes next 10 numbers in the count. Teams then chant answers in unison. Record on board. Compare 10th number in each sequence. Write £15082 on board & chn read. We’ll share this btwn 1000 chn. How [Y6] A1.b.4 much does each get? Chn estimate first. Remind chn about dividing by 1000 (move each digit 3 places to right). Choose ch to do calculation on a p/v grid and round answer down = £15.08 each. Rpt to divide same amount by 10, 10, and 10 again.
