Teach Class 4 Maths at home, one chapter at a time

Your child builds models of real buildings from blocks, then studies the flat and solid shapes inside them. The big new idea is the angle: the amount of turn at a corner, compared with a right angle (a square corner) as more than, less than or equal to it.

• angle
• right angle
• more than a right angle
• less than a right angle
• corner
• triangle
• circle
• model

The same object looks different from the top, the front and the side. Your child learns to match views to objects, draws simple views, and reads a picture from a bird’s point of view, which is how maps work.

• top view
• front view
• side view
• from above
• hidden
• visible

Rows of trees, trays of laddoos and piles of coins can be counted fast by spotting the pattern: rows times columns, trays times layers. Your child counts the same arrangement in different ways and checks they agree.

• rows
• columns
• layers
• arrangement
• pattern
• groups of

Numbers grow past 1000 into thousands. Your child reads and writes four-digit numbers, shows them with thousands, hundreds, tens and ones, writes the expanded form, compares numbers, places them on a number line and rounds them.

• thousand
• expanded form
• place value
• compare
• round to
• closest thousand

Two quarters of a page are exactly the same as one half. Your child folds, cuts and shares to find halves, quarters, three-quarters and other equal parts, writes them as fractions, and finds fractions of quantities like half a kilogram or a quarter of an hour.

• half
• quarter
• three-quarters
• equal parts
• numerator
• denominator
• fraction

Length, height, breadth and depth are all lengths. Your child uses half-metre and quarter-metre ropes, learns that 1 metre is 100 centimetres, measures with a scale correctly and estimates lengths before measuring.

• metre
• centimetre
• 100 cm = 1 m
• length
• height
• breadth
• depth
• estimate

A school trip to Mawlynnong means shopping: prices per kilogram, totals and change. Your child adds and subtracts money, estimates the bill before paying, and checks whether the money is enough.

• price
• per kg
• total
• bill
• estimate
• change
• enough
• budget

Your child moves to standard units of weight and capacity: 1 kilogram is 1000 grams, and 1 litre is 1000 millilitres. They read packet labels, fill a litre bottle from smaller bottles, and estimate weights before checking.

• kilogram (kg)
• gram (g)
• litre (L)
• millilitre (ml)
• 1000
• about
• estimate

Animals jumping 3, 4, 6 or 8 steps at a time land on multiples. Your child finds multiples, notices numbers that are multiples of two numbers, and uses equal groups to multiply and divide, including sharing with a remainder.

• multiple
• common multiple
• times
• divide
• share equally
• remainder
• groups of

Games like NIM and an addition chart build number sense, then your child adds and subtracts four-digit numbers with and without regrouping, estimating first and checking by reverse operation.

• sum
• difference
• regroup
• estimate
• check
• strategy

Your child finds lines of symmetry by folding, draws the missing half of shapes, uses a mirror to check, and makes paper-cut designs by folding a paper twice for more than one line of symmetry.

• symmetry
• line of symmetry
• mirror half
• fold
• reflection

Parv was born on 29 February, so he gets a real birthday only in a leap year. Your child learns leap years, days before and after, reads clock time in hours and minutes, and works out how long activities take.

• leap year
• 365 days
• 366 days
• hour
• minute
• duration
• day after tomorrow

Buses, trains and tempo travellers give big multiplication problems. Your child multiplies by 10, builds tables like the 15 table by splitting (5 × 15 = 5 × 10 + 5 × 5), multiplies two-digit numbers and divides larger numbers.

• times 10
• split
• array
• product
• divide
• quotient
• share

Your child learns to ask a good survey question, records answers with tally marks, organises them in a table and draws a bar graph, then answers questions from it.

• survey
• question
• tally
• table
• bar graph
• most
• least
• how many more
