 MATHS QUIZ QUIZ 76 Maths Objective To begin to understand percentage as the number of parts in every hundred and find simple percentages of small whole-number quantities. Explain... MATHS EXAMPLE Percentages and fractions are different expressions of parts of a whole one. 50% = 1 1⁄2  25% = 1⁄4 20% = 1⁄5  75% = 3⁄4 MATHS QUIZ QUIZ 77 Maths Objective To begin to understand percentage as the number of parts in every hundred and find simple percentages of small whole-number quantities. Explain... MATHS EXAMPLE Percentages and fractions are different expressions of parts of a whole one. 50% = 1 1⁄2  25% = 1⁄4 20% = 1⁄5  75% = 3⁄4 MATHS QUIZ QUIZ 78 Maths Objective To know by heart all multiplication facts and to quickly derive division facts for tables up to 12 X 12. Explain... MATHS EXAMPLE Problems can often be reduced to simple sums. A cyclist rides 5km every day. How far does she ride in 4 days? 5km x 4 = 20km MATHS QUIZ QUIZ 79 Maths Objective To know by heart all multiplication facts and to quickly derive division facts for tables up to 12 X 12. Explain... MATHS EXAMPLE Problems can often be reduced to simple sums. If 36 children sat in groups of nine, how many groups would there be? 36 ÷ 9 = 4 groups MATHS QUIZ QUIZ 80 Maths Objective To be able to quickly derive doubles of all whole numbers 1 to 100; doubles of multiples of 10 to 1000; doubles of multiples of 100 to 10 000. Explain... MATHS EXAMPLE To double numbers ending in 0, double the other digits then add back the noughts.  MATHS QUIZ QUIZ 81 Maths Objective To be able to quickly derive doubles of all whole numbers 1 to 100; doubles of multiples of 10 to 1000; doubles of multiples of 100 to 10 000. Explain... MATHS EXAMPLE To double numbers ending in 0, double the other digits then add back the noughts.  MATHS QUIZ QUIZ 82 Maths Objective To be able to quickly derive halves corresponding to doubles of all whole numbers 1 - 100, multiples of 10 to 1000 and multiples of 100 to 10 000. Explain... MATHS EXAMPLE The relationship between numbers which are multiples of 10. What is half of 24? What is half of 240? What is half of 2400? MATHS QUIZ QUIZ 83 Maths Objective To be able to quickly derive all two-digit pairs that total 100. Explain... MATHS EXAMPLE You add a number to the units to make 10. You now only need to find 90, so add a number to the tens digit to make 9. Put the two numbers together for the answer. 46 + ? = 100 Step 1: Add a number to the 6 to make 10 ⇢ (4). The units now total 10 so you only need to make the tens add up to 90. Step 2: Add a number to the tens to make 90 ⇢ (5). Put the two numbers together to make 54. MATHS QUIZ QUIZ 84 Maths Objective To be able to use known number facts and place value to mentally add any pair of two-digit whole numbers. Explain... MATHS EXAMPLE They should learn all of the following four methods, as they will all be useful with different types of number groupings.  MATHS QUIZ QUIZ 85 Maths Objective To be able to quickly derive decimals that total 10. Explain... MATHS EXAMPLE Reinforce the ‘short-cut’. There is no need to dwell on the ‘carry one’ idea. 1.7 + ? = 10 To add number to make ‘10’ Add number to make 9 You only need to make 9 because you have carried one from the previous column. MATHS QUIZ QUIZ 86 Maths Objective To be able to quickly derive all pairs of multiples of 50 with a total of 1000. Explain... MATHS EXAMPLE This exercise uses grams and kilograms, but the principle is the same for all additions. 1000g = 1kg 600g + ?g = 1000g 650g + ?g = 1000g MATHS QUIZ QUIZ 87 Maths Objective To be able to quickly derive all pairs of multiples of 50 with a total of 1000. Explain... MATHS EXAMPLE The principles of subtraction are the same whatever the measure being used. 1000g = 1kg 1000g - 100g = ?g 1000g - 150g = ?g MATHS QUIZ QUIZ 88 Maths Objective To be able to convert larger to smaller units (e.g. kg to g). Explain... MATHS EXAMPLE The relationship between fractions and division. 1kg = 1000g 1⁄2kg = 500g (e.g. 1000 ÷ 2) 1⁄4kg = 250g (e.g. 1000 ÷ 4) MATHS QUIZ QUIZ 89 Maths Objective To be able to convert larger to smaller units (e.g. kg to g). Explain... MATHS EXAMPLE The relationship between fractions and decimals, e.g. 0.5g = 1⁄2kg = 500g 1kg = 1000g 0.5kg = 500g 0.25kg = 250g MATHS QUIZ QUIZ 90 Maths Objective To be able to use all four operations to solve word problems involving numbers and quantities. Explain... MATHS EXAMPLE Word problems can be reduced to simple sums. 4 pencils cost 24p. What did one pencil cost? 24p ÷ 4 = 6p One pencil cost 6p MATHS QUIZ QUIZ 91 Maths Objective To be able to use all four operations to solve word problems involving numbers and quantities. Explain... MATHS EXAMPLE Word problems can be reduced to simple sums. I was given 17p change from 50p How much had I spent? 50p – 17p = 33p I spent 33p MATHS QUIZ QUIZ 92 Maths Objective To be able to count forwards or backwards in steps of 10 starting from any two-digit number. Explain... MATHS EXAMPLE These are addition and subtraction sums involving two 2-digit numbers. 19 + 10 = 29 39 - 10 = 29 MATHS QUIZ QUIZ 93 Maths Objective To be able to count forwards or backwards in steps of 100 starting from any three-digit number. Explain... MATHS EXAMPLE These are addition and subtraction sums involving two 3-digit numbers. 637 + 100 = 737 637 - 100 = 537 MATHS QUIZ QUIZ 94 Maths Objective To be able to count forwards or backwards in steps of different sizes. Explain... MATHS EXAMPLE They will need to recognise the pattern in each group of numbers. Counting forwards: 10 ⇢ 20 ⇢ 30 ⇢ 40 ⇢ 50 Counting backwards: 78 ⇢ 68 ⇢ 58 ⇢ 48 ⇢ 38 MATHS QUIZ QUIZ 95 Maths Objective To be able to read the time to the nearest minute from an analogue clock. Explain... MATHS EXAMPLE That they are to answer the questions on the attached sheet by drawing the hands of the clock on the numbered clock faces. An analogue clock similar to the face shown on the attached questions sheet. Use this drawing on which to display the answers to questions 3, 4, 6, 8 – 12  MATHS QUIZ QUIZ 96 Maths Objective To know and apply tests of divisibility by 2, 4, 5, 10 or 100. Explain... MATHS EXAMPLE A number that can be divided exactly into another number is called a factor of that number.  MATHS QUIZ QUIZ 97 Maths Objective To consolidate and apply tests of divisibility. Explain... MATHS EXAMPLE This is a test of their ability to recognise factors. Identify two factors of the following numbers (apart from the number itself and 1). MATHS QUIZ QUIZ 98 Maths Objective To consolidate the material contained in exercises 76 – 96. Explain... MATHS REVISION This is a test of the topics previously covered. MATHS QUIZ QUIZ 99 Maths Objective To practise SATs questions. Explain... MATHS SATs PRACTICE Practising these types of questions will help them in their tests.
