Numbers

Add and subtract integers

On a number line, adding a positive moves right; adding a negative moves left. Subtracting a number = adding its opposite.

Builds on: Lakhs and crores

Try it:

  1. (−17) − 7 = ? → −24
  2. (−8) + 10 = ? → 2

Compare integers

On a number line, numbers to the right are bigger. Every positive is bigger than every negative; −2 > −9.

Builds on: Add and subtract integers

Try it:

  1. Choose the sign: 0 ☐ 27 → <
  2. Choose the sign: −17 ☐ 29 → <

Evaluate algebraic expressions

Replace the letter with its value, then follow BODMAS: multiply before you add.

Builds on: 2-digit × 2-digit

Try it:

  1. If x = 7, what is 3x − 4? → 17
  2. If x = 12, what is 5x − 2? → 58

Solve simple equations

Do the same thing to both sides to get x on its own: undo + with −, undo × with ÷.

Builds on: Evaluate algebraic expressions

Try it:

  1. Solve: x + 13 = 18 → 5
  2. Solve: x + 10 = 22 → 12

Multiplication & division

Prime factorisation

Keep dividing by the smallest prime (2, 3, 5, 7…) until you reach 1. Multiply the primes back to check.

Builds on: Prime and composite numbers

Try it:

  1. Which is the prime factorisation of 48? → 2 × 2 × 2 × 2 × 3
  2. Which is the prime factorisation of 75? → 3 × 5 × 5

Divisibility rules

2: even · 3: digit sum divisible by 3 · 4: last two digits · 5: ends in 0/5 · 6: by 2 and 3 · 9: digit sum divisible by 9 · 10: ends in 0.

Builds on: Factors and multiples

Try it:

  1. Which number is divisible by 3 ? → 528
  2. Which number is divisible by 4 ? → 644

Fractions & decimals

Multiply fractions

Multiply tops together and bottoms together, then simplify.

Builds on: Add unlike fractions

Try it:

  1. 6/8 × 1/3 = ? (simplest form) → 1/4
  2. 4/9 × 1/7 = ? (simplest form) → 4/63

Multiply decimals by whole numbers

Multiply as if there were no point, then put the point back with the same number of decimal places.

Builds on: Add and subtract decimals

Try it:

  1. 0.125 × 9 = ? → 1.125
  2. 0.75 × 4 = ? → 3

Ratios in simplest form

Divide both parts of the ratio by their HCF: 12 : 18 → 2 : 3.

Builds on: HCF and LCM

Try it:

  1. Simplify the ratio 14 : 21 → 2 : 3
  2. Simplify the ratio 14 : 7 → 2 : 1

Percent, fraction and decimal

Per cent → divide by 100: 35% = 35/100 = 0.35 = 7/20.

Builds on: Percentages

Try it:

  1. Write 45% as a fraction in simplest form. → 9/20
  2. Write 80% as a decimal. → 0.8

Word problems

The unitary method

Find the value of ONE first, then multiply for many.

Builds on: Division with remainders, 2-digit × 2-digit

Try it:

  1. If 4 stars cost ₹16, how much do 9 stars cost? → 36
  2. If 6 balloons cost ₹180, how much do 10 balloons cost? → 300

Measurement

Perimeter of polygons

Perimeter = sum of all sides. A regular polygon has equal sides, so perimeter = number of sides × side.

Builds on: Area and perimeter of squares

Try it:

  1. What is the perimeter of a regular pentagon with sides of 18 cm? → 90
  2. What is the perimeter of a regular octagon with sides of 3 cm? → 24

Shapes & patterns

Complementary and supplementary angles

Complementary angles add to 90°. Supplementary angles add to 180° (angles on a straight line).

Builds on: Angles in a triangle

Try it:

  1. What is the supplement of 101°? → 79
  2. What is the complement of 43°? → 47

Data handling

Mean and range

Range = largest − smallest. Mean = total ÷ how many.

Builds on: Average (mean)

Try it:

  1. Find the range of 48, 54, 20, 33. → 34
  2. Find the mean of 21, 11, 11, 11, 15, 33. → 17

Reasoning (ThinkLab)

Meeting point

When two travel towards each other, their speeds add: time to meet = distance ÷ (speed₁ + speed₂).

Builds on: Speed, distance and time

Try it:

  1. Two towns are 600 km apart. Two cars start towards each other at 60 km/h and 60 km/h. After how many hours do they meet? → 5
  2. Two towns are 250 km apart. Two cars start towards each other at 20 km/h and 30 km/h. After how many hours do they meet? → 5

Age puzzles

Use the difference: if Riya is 4 years older and their ages add to 30, take away the 4 and share the rest equally.

Builds on: Solve simple equations

Try it:

  1. Kabir is 6 years older than Zara. Their ages add up to 34. How old is Kabir? → 20
  2. Kabir is 6 years older than Sara. Their ages add up to 40. How old is Kabir? → 23
