Do they want to change their mind money banks with coins visible inside. They draw lines to match the having listened to their partner? Explain to children that it is okay to money banks to three children, based on information about the amount change your mind. Discuss with children how they might show this in of money each child has. their book. Encourage them not to rub out or scribble over the answer. Once children have done this, they work in pairs to compare their Would you rather have 1p pocket money each day, or 10p each week? answers. Extra help Provide 1p coins laid out in sets to match the amounts in the three money banks. This will allow children to take away 1p to find the answer. Focus on exchanging the pennies for other coins, e.g. 2p is 2 ≠ 1p. Be aware Outcomes • Relating problem solving in books to a context requires children • I can use clues to solve problems. to understand the ideas in the problem and apply them to a range • I can take amounts away from 10p. of different scenarios. Using words and pictures to do this is an important skill.

    • D1: sorting and describing 2D shapes; line symmetry; counting Challenge Plan: Year 2 back in 1s, not crossing a ten; counting back in 1s, crossing a ten Summary Y2 D1.2 What’s missing? Individuals or pairs working independently Year 2 Challenge Textbook page 5 Paper; scissors; mirror card Abacus Evolve objectives Framework objectives • Begin to recognise line symmetry • Identify reflective symmetry in patterns and 2D shapes and draw • Make symmetrical patterns by folding and cutting lines of symmetry in shapes • Begin to sketch the reflection of a simple shape in a mirror line • Describe patterns and relationships involving numbers or shapes, make predictions and test these with examples • Listen to others in class, ask relevant questions and follow instructions Teacher notes Preparation Further extension Cut up some mirror card so you have one piece per pair. Ask children to work in pairs. They sit opposite each other with a piece of paper between them. Set up a barrier (such as a big book or a game Getting started board) between the children, so that the barrier divides the piece of Show Textbook page 5. Explain that the shapes are all symmetrical, but paper in two. Explain to children that they are going to pretend that the they have been cut in half by mistake. Make sure children understand barrier is a mirror. One child draws a shape on their side of the paper what this means. How could you find out what is missing? and as they are drawing it they describe it to their partner. The second child has to follow the instructions, reversing them in their head, in Activity order to draw the reflection of the shape. This is difficult, but fun and Children work from Textbook page 5. Each child copies the half intended to draw attention to the process of reflection. Children can pictures, and then tries to complete them. They compare their pictures check their images with a piece of mirror card when finished. with a partner, and talk about what methods they used. They check their pictures by holding a piece of mirror card along the line of If you have time symmetry. Give children a digital camera and ask them to take some photos of symmetrical objects. Print the pictures and then cut them in half. Extra help Children give one half to a partner to complete, then check by sticking Photocopy the Textbook page so that children can complete the the picture back together. pictures, without having to copy them first. Be aware Outcomes • Deciding on the line of symmetry is important and children need • I can recognise line symmetry. to realise that this has been pre-determined by where the pictures • I can make symmetrical patterns by folding and cutting. have been cut.

    • A1: comparing 3-digit numbers; partitioning 3-digit numbers; Challenge Plan: Year 3 counting objects by grouping; counting on and back in 100s Summary Y3 A1.1 Growing on trees Individuals, pairs or groups working independently Year 3 Challenge Textbook page 7 Year 3 Challenge PCMs 1 and 2 Timer Abacus Evolve objectives Framework objectives • Read and write numbers up to 1000 in figures and words • Read, write and order whole numbers to at least 1000 and position • Count on in 5s to 100, and in 50s to 1000 them on a number line; count on from and back to zero in single- • Add and subtract a multiple of 10 to and from a 3-digit number, digit steps or multiples of 10 crossing 100 • Add or subtract mentally combinations of one-digit and two-digit • Add and subtract a multiple of 100 to and from a 4-digit number, numbers crossing 1000 • Identify patterns and relationships involving numbers or shapes, • Extend understanding that subtraction is the inverse of addition and use these to solve problems Teacher notes Preparation If you have time Photocopy PCMs 1 and 2, one copy of each per child. Children will find it useful to discuss their patterns. Often children will have different insights that combine to give all of them a better picture. Getting started Check that children understand how the code-hexagon below the tree informs them what number to write in each space. Activity Children work from Textbook page 7 and record their answers on PCMs 1 and 2. They use two rules to fill in the numbers in a tree- shaped arrangement of hexagons, and then go back and find the missing four rules. Ask the group to start the puzzle at the same time, starting a timer as they do so. As each child finishes, they write their time, to the nearest half minute, in the star at the top of the tree. Children then compare their trees. They should notice how the patterns work in all six directions, and recognise that inverse rules apply for opposite directions. They should also notice that hexagons to the left or right of each other are affected by a combination of the rules. Children then complete a second tree, before going on to make up their own rules for two more trees. Be aware Outcomes • Children may be unfamiliar with the idea behind the code-hexagon • I can explore and record patterns in numbers. to represent changes in all directions. If necessary, go through • I can recognise general patterns when adding and subtracting. question 1 together. 6 www.pearsonschools.co.uk/abacusevolve
    • Counting Growing on trees A1 Here is a tree of numbers. 1000 The larger numbers are at the base and the smallest number is at the top. The hexagon below the tree shows the rule for changing the numbers as you move in different directions. We have been given the rules for moves in two directions. We can use these to complete the tree. We can then complete the hexagon to show the rules for + 100 + 500 all six directions. 1 Complete the first tree on PCM 1. Time how long it takes you and write your time, to the nearest half minute, in the star on top of your tree. Does everyone’s tree look the same? 2 Complete the next tree on PCM 1. It has different rules! 3 Complete the two trees on PCM 2. Make up your own rules for these trees. What rules did other people in the group make up? Copy this diamond pattern onto squared paper. Write 1 in the bottom box. Complete the diamond. What do you notice about ≠2 ≠5 the patterns of numbers? If you start with another small number, such as 4, what patterns result? 7

Also, Discuss with the group the results of these multiplications: preparing a simple sheet with three boxes in a line as on the Textbook 2 ≠ 5 ≠ 6 2 ≠ 6 ≠ 5 5 ≠ 2 ≠ 6 5 ≠ 6 ≠ 2 page may help to keep children’s recording neater. 6 ≠ 2 ≠ 5 6 ≠ 5 ≠ 2 All the products are 60. Does this work for other sets of three numbers Activity in different orders? Why is this? Children work from Textbook page 11. They multiply sets of three digits and find the products. Information Children then use number cards to make their own multiplications Children may recognise that any set of three digits will always give the of three digits. They find the products and record these (they do not same product. This may give insight into two laws of arithmetic: reveal the multipliers to other children). They then swap sheets and find The commutative law: a ≠ b = b ≠ a the multipliers that would make each product. The associative law: a ≠ (b ≠ c) = (a ≠ b) ≠ c. Together these laws mean that any three numbers multiplied in any Further extension order give the same overall product. Using calculators, children can extend their range of multiplying up to 9 ≠ 9 ≠ 9 to produce further, more challenging puzzles. Others in the group use calculators to deduce the digits that have been multiplied. Be aware Outcomes • Some children may be unused to multiplying three numbers • I can multiply three small numbers together. together, and surprised by how large a product results. • I can work out which three digits have been multiplied together to give a product. • I can create puzzles for others to solve. 10 www.pearsonschools.co.uk/abacusevolve

Show your working. Write out the product (but not the multipliers). Swap with someone in your group. Can you find the multipliers to make their product? What always happens to the product if … • one of the three digits chosen is a 2? • one of the three digits chosen is a 5? • one digit is even and another is a 5? 11
    • B2: multiplication; doubling and halving; coordinates; names Challenge Plan: Year 5 and properties of 2D shapes Summary Y5 B2.2 Egyptian multiplication Individuals, pairs or groups working independently Year 5 Challenge Textbook page 13 Calculators (optional) Abacus Evolve objectives Framework objectives • Use doubling and halving to help multiply • Extend mental methods for whole-number calculations, e.g. to • Use doubling or halving to find new facts from known facts multiply a 2-digit by 1-digit number (e.g. 12 ≠ 9), to multiply by 25 • Multiply using closely related facts (e.g. 16 ≠ 25), to subtract one near multiple of 1000 from another (e.g. 6070 ≠ 4097) • Represent a puzzle or problem by identifying and recording the information or calculations needed to solve it; find possible solutions and confirm them in the context of the problem Teacher notes Preparation Further extension Familiarise yourself with the Egyptian multiplication method by looking Children could use the Egyptian multiplication method to work out the at Textbook page 13. calculations from Activity B2.1. Getting started Ask children to practise doubling some random numbers before they start the activity. Activity Children work from Textbook page 13. They learn about the Egyptian number system and the Egyptian method for multiplication. This method involves doubling and children should be encouraged to choose an appropriate doubling strategy for each number. For 2-digit numbers children should be able to partition and double mentally. Some may also be able to do this for 3-digit numbers, or they may prefer a mixture of mental strategies and jottings. The method works in exactly the same way for 3-digit numbers. Children can use other methods or a calculator to check their answers. Be aware Outcomes • Doubling 3-digit numbers mentally (particularly when the hundreds • I can use a new multiplication method. digit is more than 5) can be much trickier than doubling 2-digit • I can double to help me multiply. numbers. Encourage children to make notes to help them with the • I can estimate and check calculations using different methods. calculation.

    • Multiplication Egyptian multiplication and division B2 The Ancient Egyptians used symbols to represent numbers: 1 10 100 1000 10 000 100 000 1 000 000 There was no symbol for zero. They had to draw several of each symbol for each number. For example, 213 would be written as Have a go at writing some other numbers using the Ancient Egyptian symbols. The Egyptians had their own way of solving multiplications. They used doubling. 1 23 To solve 46 ≠ 23, draw a table with 2 46 1 in the left-hand column and 23 in 4 92 the right-hand column. Double the 8 184 numbers in each column until the number in the left-hand column is 16 368 greater than 46. 32 736 64 1472 Find the numbers in the left-hand column that total 46. 32 + 8 + 4 + 2 = 46 Add together the corresponding numbers in the right-hand column. 736 + 184 + 92 + 46 = 1058 Check your answer using another method or with a calculator. Estimate the answers to the following calculations then use the Egyptian method to find the answers. 1 21 ≠ 36 2 31 ≠ 27 3 39 ≠ 52 4 53 ≠ 28 5 77 ≠ 43 Does this method work with 3-digit numbers? Make up some calculations with 3-digit numbers and try it out! 13
