Knowing our numbers

Compare, order, round and estimate with numbers of four digits and more.

Before you start

Move between four thousand and five thousand, a hundred at a time. Watch which end of the line you are nearer.

400045005000

Halfway is 4500. Everything to the left of it is nearer 4000 and everything to the right is nearer 5000 — which is the whole of rounding to the nearest thousand, and why 4783 goes up rather than down.

  1. 1.Make the largest number you can from the digits 4, 7, 1 and 9, using each digit once.

  2. 2.Round 4678 to the nearest hundred, then tap it on the line.

    Mark the line with an X.

    4400450046004700480049005000

  3. 3.Which of these is the largest number?

    • a) 46857
    • b) 46587
    • c) 46875
    • d) 46785

  4. 4.Put these numbers in order, smallest first.

    • 9899
    • 98909
    • 9989
    • 98990
    • 98099

  5. 5.Make the smallest number you can from the digits 5, 2, 8 and 6, using each digit once.

  7. 7.What is the predecessor of 40000?

  8. 8.Sort each number by whether it is closer to 5000 or to 6000.

    Groups: Closer to 5000 · Closer to 6000

    • 5120
    • 5499
    • 5750
    • 5045

Whole numbers

Use the order, identity, grouping and splitting properties of whole numbers to make arithmetic easier.

Before you start

Move along the whole numbers. Notice that each one has a next one, and that only zero has nothing before it.

0123456789101112

The line stops at 0 on the left because that is where the whole numbers start — but it never has to stop on the right.

  1. 1.Which of these is NOT a whole number? (The whole numbers are 0, 1, 2, 3, …)

    • a) 0
    • b) 17
    • c) -4
    • d) 206

  2. 2.What is the successor of 6099?

  3. 3.25 × 17 × 4 = ?

  4. 4.Work out each one, then sort it by whether the answer is a whole number. (The whole numbers are 0, 1, 2, 3, …)

    Groups: Is a whole number · Is not a whole number

    • 3 - 8
    • 6 × 0
    • 12 ÷ 4
    • 12 ÷ 5
    • 7 - 7
    • 9 ÷ 2

Factors and multiples

Find factors and multiples, use divisibility tests, and tell a prime number from a composite one.

Before you start

Every mark on this line is a multiple of 3. Move along them and see how many you already know from the 3 times table.

061218243036

The line could carry on for ever, because a number has no last multiple. Factors go the other way: 36 has exactly nine of them and then they run out.

  1. 1.Which of these numbers is divisible by 9?

    • a) 4651
    • b) 4650
    • c) 4652
    • d) 4653

Year 7 Maths · 4 of 13

HCF and LCM

Find the highest common factor and the lowest common multiple of two numbers, and use them to answer sharing and repeating problems.

Before you start

Every mark here is a multiple of 4 and a multiple of 6 at the same time. Move from one to the next.

01224364860

Zero is a multiple of everything, so it never counts. The first mark after it is 12, and that is what the LCM of 4 and 6 means — the earliest place their two lists of multiples meet.

  1. 1.Work out the LCM of each pair, then sort by whether it is below 30 or above 30.

    Groups: LCM below 30 · LCM above 30

    • 9 and 12
    • 3 and 8
    • 4 and 6
    • 5 and 8
    • 7 and 10
    • 6 and 9

  2. 2.One bell rings every 6 minutes and another rings every 8 minutes. They have just rung together. In how many minutes will they next ring together?

Understanding fractions

Place fractions on a number line, find equivalent fractions, compare them, and switch between mixed numbers and improper fractions.

Before you start

Move along the line and watch the quarters go past. See which fractions land on a whole number and which land between two of them.

0.001.002.00

Every fourth step lands on a whole number, because four quarters make one whole. That is the same fact as 4/4 = 1.

  1. 1.What fraction of an hour is 45 minutes? Write it in its simplest form.

  2. 2.Match each fraction to an equivalent one with a larger bottom number.

    • 1/2

    • 3/4
    • 2/3
    • 4/12
    • 10/15
    • 9/12
    • 8/20
    • 5/10

  3. 3.Which of these fractions is NOT equivalent to 2/3?

Decimals

Compare and order decimals, add and subtract them, and switch between decimals and fractions.

Before you start

Move between 3 and 4 in tenths. A whole line of numbers is hiding between two whole ones.

3.03.13.23.33.43.53.63.73.83.94.0

Nothing says the line has to stop at tenths. Chop each of these gaps into ten again and hundredths appear — 3.14, 3.15 — and you could keep chopping for ever.

  1. 1.Put these decimals in order, smallest first.

    • 0.09
    • 0.5
    • 0.4
    • 1.05
    • 0.41

  5. 5.Write 7/10 as a decimal.

  6. 6.Which of these decimals is the largest?

    • a) 0.68
    • b) 0.7
    • c) 0.609
    • d) 0.5

  7. 7.Sort each decimal by whether it is closer to 0 or closer to 1.

    Groups: Closer to 0 · Closer to 1

    • 0.91
    • 0.7
    • 0.2
    • 0.09
    • 0.55

Basic geometrical ideas

Tell points, lines, rays and line segments apart, name the parts of an angle and a circle, and count the sides and diagonals of a polygon.

Before you start

Three lines are drawn on this circle. Take them in turn and find out what each one is called, looking at where each one starts and where it ends.

123
  1. 1. Radius — centre to edge
  2. 2. Diameter — right across, through the centre
  3. 3. Chord — edge to edge, missing the centre

Every diameter is also a chord — it is simply the longest one, and the only kind that passes through the centre.

    123

  7. 7.Put these shapes in order by how many sides they have, fewest first.

    • Quadrilateral
    • Triangle
    • Hexagon
    • Pentagon
    • Octagon

  8. 8.A line has no ends, a ray has one end, and a line segment has two. Which of the three has a length you could measure with a ruler?

    • a) A line
    • b) All three of them
    • c) A line segment
    • d) A ray

1234
  1. 1. Acute
  2. 2. Right angle
  3. 3. Obtuse
  4. 4. Straight

Acute is under 90°, obtuse is over it, and the straight one is a half turn — 180°, which is why it stopped looking like a corner at all.

  3. 3.Put these kinds of angle in order by size, smallest first.

    • Obtuse
    • Acute
    • Right
    • Straight
    • Reflex

  4. 4.This triangle has one right angle. Tap the corner where it is.

    Write the number of the part.

    123

  5. 5.Sort each shape by whether it is flat or solid.

    Groups: Flat shape · Solid shape

    • Sphere
    • Triangle
    • Cube
    • Cylinder
    • Square
    • Circle

  6. 6.Match each angle to the name for its size.

    • 45°
    • 90°
    • 120°
    • 180°
    • 300°
    • Acute
    • Straight
    • Right
    • Obtuse
    • Reflex

  7. 7.An angle of 145° is which kind of angle?

    • a) Acute
    • b) Right
    • c) Reflex
    • d) Obtuse

  8. 8.All three angles of an equilateral triangle are equal, and they add up to 180°. How big is each one, in degrees?

Lines and angles

Use complementary, supplementary, vertically opposite and parallel-line angle facts.

Before you start

Two straight lines cross, and only one of the four angles they make has been given to you. Find out how big each of the others is.

1234
  1. 1. 70° — given
  2. 2. 110° — supplementary
  3. 3. 70° — opposite
  4. 4. 110° — also opposite

Going round the crossing the angles read 70, 110, 70, 110. Each neighbouring pair sits on a straight line and adds to 180°, and each opposite pair is equal — which is the same fact told twice.

  1. 1.Parallel lines are cut by a transversal. One co-interior angle is 115°. What is the other, in degrees?

  2. 2.Match each angle to its complement — the angle that makes it up to 90°.

    • 20°
    • 35°
    • 10°
    • 25°
    • 40°
    • 55°
    • 70°
    • 65°
    • 50°
    • 80°

  3. 3.Sort each angle as acute or obtuse.

    Groups: Acute · Obtuse

    • 92°
    • 170°
    • 12°
    • 78°
    • 145°
    • 35°

  4. 4.Two angles sit on a straight line, and one is three times the other. How big is the smaller one, in degrees?

  5. 5.Two straight lines cross. One of the four angles is 130°. What is the angle next to it, in degrees?

  6. 6.Two angles are complementary. One of them is 65°. What is the other, in degrees?

  7. 7.Angles round a point add up to how many degrees?

  8. 8.A pair of parallel lines is cut by a transversal. Alternate angles are always...

    • a) right angles
    • b) complementary
    • c) supplementary
    • d) equal

    Groups: Proves congruence · Does not prove congruence

    • AAA
    • ASA
    • SSA
    • SAS
    • SSS
    • RHS

  8. 8.Is knowing that all three pairs of angles are equal enough to prove two triangles congruent?

    • a) Yes, always
    • b) Only for right-angled triangles
    • c) Only for isosceles triangles

Pictographs and bar graphs

Record data with tallies, read pictographs and bar graphs where one unit stands for many, and answer questions from them.

Before you start

Every line across this graph is worth 5 books. Look at how far up each bar reaches and work out what it is worth.

1234
  1. 1. Monday — 30 books
  2. 2. Tuesday — 15 books
  3. 3. Wednesday — 40 books
  4. 4. Thursday — 25 books

Count the lines, not the bars. Monday reaches six lines up and each line is worth 5 books, which is why it is 30 and not 6 — that is the whole job a scale does.

Move the bars up and down, and watch the number each one stands for.

Each line up the side is worth 5.0510152025303540MondayTuesdayWednesday

One line up is not one book. Every line you cross is worth 5, so a bar that grows by one line grows by five — that is the scale doing its job.

  1. 1.A bar graph shows 6, 11, 9 and 4 goals across four matches. In how many of the matches were fewer than 8 goals scored?

  2. 2.A shop sold 14 pens on Monday, 9 on Tuesday, 21 on Wednesday and 17 on Thursday. Put the days in order, fewest pens first.

    • Thursday
    • Tuesday
    • Monday
    • Wednesday

  3. 3.A bar graph shows 12 red, 8 blue, 15 green and 5 yellow counters. How many counters are there altogether?

  4. 4.This bar chart shows how many apples a stall sold on four days. Tap the bar for the day it sold the most.

    Write the number of the part.
