Question 1 of 33

1 Paper 1 · Write the missing numbers.

35 + = 100

450 + = 1000

Working: count up to the next whole number.

100 − 35 = 65.
1000 − 450 = 550.

LO: 6Nc1 — number bonds to 100 / 1000.

2 Paper 1 · Double 67.

Double 67 =

Working: double 60 = 120, double 7 = 14, so 120 + 14 = 134.

LO: 6Nc9 — double a two-digit number.

3 Paper 1 · Complete the calculations.

56 × 10 =

4200 ÷ 10 =

Working:

×10 shifts every digit one place left: 56 → 560.
÷10 shifts every digit one place right: 4200 → 420.

LO: 6Nn4 — multiply / divide by 10.

4 Paper 1 · Round the number 3650.

to the nearest 100 =

to the nearest 1000 =

Working: look at the digit just after the rounding place.

Nearest 100: the tens digit is 5, so round up → 3700.
Nearest 1000: the hundreds digit is 6 (5 or more), so round up → 4000.

LO: 6Nn8 — round whole numbers to the nearest 10, 100 or 1000.

5 Paper 1 · What is the value of the digit 4 in the number 5.46?

4 tenths 4 hundredths 4 units 4 tens

Working: the first place after the decimal point is tenths. In 5.46 the 4 is in the tenths place, so it is worth 4 tenths.

LO: 6Nn3 — place value in decimals.

6 Paper 1 · Work out 3/5 of 40.

3/5 of 40 =

Working: 1/5 of 40 = 40 ÷ 5 = 8, then 3/5 = 3 × 8 = 24.

LO: 6Nc21 — find fractions of quantities.

7 Paper 1 · A rectangle is 7 cm long and 4 cm wide. Work out its perimeter.

Perimeter = cm

Working: perimeter = all four sides = 2 × (7 + 4) = 2 × 11 = 22 cm.

LO: 6Ma1 — perimeter of a rectangle.

8 Paper 1 · Here are some scores: 2, 3, 3, 5, 3, 2. What is the mode?

3 2 5 3.5

Working: the mode is the value that appears most often. 3 appears three times, more than any other, so the mode is 3.

LO: 6Dh2 — find the mode of a set of data.

9 Paper 1 · The temperature is −6 °C. It rises to 9 °C. By how many degrees did it rise?

Rise = degrees

Working: count up through zero. From −6 up to 0 is 6 degrees; from 0 up to 9 is 9 degrees. 6 + 9 = 15 °C.

LO: 6Nc13 — difference across negative numbers.

10 Paper 1 · Tick ALL the prime numbers in this list.

7 13 2 9 15

Working: a prime has exactly two factors — 1 and itself. 2, 7 and 13 are prime. 9 = 3×3 and 15 = 3×5, so they are not prime.

LO: 6Nn19 — recognise prime numbers.

11 Paper 1 · Write in the missing number.

6000 − = 250

Working: if 6000 − ? = 250, then ? = 6000 − 250 = 5750.

LO: 6Pt3 — check / find a missing number using the inverse.

12 Paper 1 · A triangle has three equal sides. What is its name?

Equilateral Isosceles Scalene Right-angled

Working: a triangle with all three sides equal is equilateral (its three angles are also equal, 60° each).

LO: 6Gs1 — classify shapes by their properties.

13 Paper 1 · Two angles in a triangle are 50° and 60°. Work out the third angle.

Third angle = degrees

Working: the angles in a triangle add up to 180°. 180 − 50 − 60 = 70°.

LO: 6Gs6 — calculate angles in a triangle.

14 Paper 1 · Put these decimals in order, starting with the smallest.

Drag items to reorder. Arrange the 4 items in the correct sequence.

0.44
0.14
0.04
0.4

Working: compare the tenths first, then the hundredths. 0.04 (0 tenths) is smallest, then 0.14, then 0.4, then 0.44.

Order: 0.04, 0.14, 0.4, 0.44

LO: 6Nn14 — order numbers with up to two decimal places.

15 Paper 1 · Use the fact 24 × 8 = 192 to complete these.

24 × 16 =

2.4 × 8 =

Working:

16 is 8 × 2, so 24 × 16 = 192 × 2 = 384.
2.4 is 24 ÷ 10, so 2.4 × 8 = 192 ÷ 10 = 19.2.

LO: 6Nc17 — use known facts to derive new ones.

16 Paper 1 · Complete the calculations.

7 × 100 =

90 ÷ 100 =

Working:

×100 shifts every digit two places left: 7 → 700.
÷100 shifts every digit two places right: 90 → 0.9.

LO: 6Nn5 — multiply / divide by 100.

17 Paper 1 · Write this fraction in its simplest form.

8/10 =

Working: divide top and bottom by the same number. 8 ÷ 2 = 4 and 10 ÷ 2 = 5, so 8/10 = 4/5.

LO: 6Nn26 — reduce fractions to their simplest form.

18 Paper 1 · Mia says, “When you add two odd numbers, the answer is always even.” Give one example that shows Mia is correct.

Marks: 1 points

Model answer: Pick two odd numbers and add them, for example 3 + 5 = 8, which is even — so Mia is correct. (Any two odd numbers give an even total: you must show the calculation.)

LO: 6Nn18 — general statements about sums of odd / even numbers.

19 Paper 2 · Select the TWO numbers that have a total of 500.

120 380 250 340 190

Working: look for a pair that adds to 500. 120 + 380 = 500. No other pair in the list makes 500.

LO: 6Nc4 — number bonds / mental addition.

20 Paper 2 · Write the next two numbers in this sequence.

1.5, 3, 4.5, 6, ,

Working: each term goes up by 1.5.

6 + 1.5 = 7.5.
7.5 + 1.5 = 9.

LO: 6Nn15 — recognise and extend number sequences.

21 Paper 2 · Two angles meet on a straight line. One angle is 115°. Work out the other angle.

Other angle = degrees

Working: angles on a straight line add up to 180°. 180 − 115 = 65°.

LO: 6Gs6 — calculate angles on a straight line.

22 Paper 2 · Drag each calculation onto its answer.

Drag each item into the correct category. Place all 4 items into the 4 categories below.

1/2 of 84
3/4 of 84
1/4 of 84
1/3 of 84

1/2 of 84

1/4 of 84

3/4 of 84

1/3 of 84

Working: 1/2 of 84 = 42; 1/4 of 84 = 84÷4 = 21; 3/4 of 84 = 21×3 = 63; 1/3 of 84 = 84÷3 = 28.

LO: 6Nc21 — fractions of an amount.

23 Paper 2 · Work out each calculation. Remember the order of operations.

7 + 3 × 4 =

(7 + 3) × 4 =

Working: do brackets and multiplication before addition.

7 + 3 × 4 — multiply first: 3 × 4 = 12, then 7 + 12 = 19.
(7 + 3) × 4 — brackets first: 10 × 4 = 40.

LO: 6Nc22 — order of operations / arithmetic laws.

24 Paper 2 · Work out these percentages.

20 per cent of 150 =

75 per cent of 80 =

Working:

20 per cent = one fifth: 150 ÷ 5 = 30.
75 per cent = three quarters: 80 ÷ 4 = 20, then 20 × 3 = 60.

LO: 6Nn29 — find percentages of whole numbers.

25 Paper 2 · 3 kg of apples cost $4.50. How much do 5 kg of apples cost?

Cost = $

Working: find the cost of 1 kg first: $4.50 ÷ 3 = $1.50. Then 5 kg = 5 × $1.50 = $7.50.

LO: 6Ps7 — ratio / direct proportion (scaling).

26 Paper 2 · Point A is at (−2, −1). It moves 4 squares UP. Write the new coordinates.

New point = ( , )

Working:

Moving up does not change the x-coordinate, so it stays −2.
Moving 4 up adds 4 to the y-coordinate: −1 + 4 = 3.

So the new point is (−2, 3).

LO: 6Gp1 — co-ordinates in all four quadrants.

27 Paper 2 · A quadrilateral has four equal sides but no right angles. What is it?

Rhombus Square Rectangle Trapezium

Working: four equal sides with no right angles is a rhombus. (A square also has four equal sides but it has right angles.)

LO: 6Gs3 — classify quadrilaterals.

28 Paper 2 · A film starts at 13:50 and ends at 15:25. How long is the film, in minutes?

Length = minutes

Working: from 13:50 to 14:50 is 60 minutes, then 14:50 to 15:25 is 35 minutes. 60 + 35 = 95 minutes.

LO: 6Mt5 — calculate time intervals.

29 Paper 2 · A rectangle is 9 cm long and 6 cm wide. Work out its area.

Area = cm²

Working: area of a rectangle = length × width = 9 × 6 = 54 cm².

LO: 6Ma1 — area of a rectangle.

30 Paper 2 · Pencils are packed in boxes of 8. How many boxes are needed for ALL of 250 pencils?

Boxes needed =

Working: 250 ÷ 8 = 31 remainder 2. 31 boxes hold 248 pencils, leaving 2 over, so you need 1 more box. 31 + 1 = 32.

LO: 6Nc19 / 6Ps6 — divide with a remainder and round up to solve a word problem.

31 Paper 2 · Write 3/4 as a decimal and as a percentage.

3/4 as a decimal =

3/4 as a percentage = per cent

Working:

3 ÷ 4 = 0.75.
0.75 = 75 in every 100 = 75 per cent.

LO: 6Nn27 / 6Nn28 — fraction ↔ decimal ↔ percentage.

32 Paper 2 · Convert these measurements.

3.2 km = m

1500 g = kg

Working:

1 km = 1000 m, so 3.2 × 1000 = 3200 m.
1 kg = 1000 g, so 1500 ÷ 1000 = 1.5 kg.

LO: 6Ml2 — convert between units of measurement.

33 Paper 2 · A smoothie recipe for 2 people uses 150 ml of milk. How much milk is needed for 6 people?

Milk = ml

Working: 6 people is 3 times as many as 2, so multiply the milk by 3: 150 × 3 = 450 ml.
