Mini Lesson
Congratulations on completing Grade 4 Math! This review covers all four units: Numbers and Place Value, Operations, Fractions and Decimals, and Geometry and Data.
Units 1 and 2 — Numbers and Operations
- Numbers to 1 million: place value, comparing, ordering, rounding to 10, 100, and 1,000.
- Factors, multiples, prime and composite numbers.
- Multiplication and division of 2- and 3-digit numbers; order of operations; multi-step word problems.
Unit 3 — Fractions and Decimals
- Identify, compare, and find equivalent fractions; add and subtract fractions.
- Mixed numbers and improper fractions.
- Decimals to hundredths; relate fractions to decimals; round and compare decimals.
Unit 4 — Geometry and Data
- Angles (acute, right, obtuse, straight) and polygons; classify triangles and quadrilaterals.
- Area (A = l × w), perimeter (P = 2(l + w)), and volume (V = l × w × h).
- Coordinate grids, metric conversions, symmetry and patterns.
Words to know
place value
The value of a digit based on its position in a number.
e.g. In 4,562, the digit 5 is in the hundreds place.
equivalent fractions
Fractions that name the same amount with different numerators and denominators.
e.g. 1/2 = 2/4 = 4/8.
mixed number
A whole number combined with a fraction.
e.g. 2 1/2 means 2 wholes and one half.
decimal
A number that uses a decimal point to show parts smaller than 1.
e.g. 0.75 means 75 hundredths or 3/4.
polygon
A closed flat shape with straight sides.
e.g. Squares, triangles, and pentagons are all polygons.
volume
The amount of space a 3D solid fills, in cubic units.
e.g. A box 3 × 4 × 5 cm has volume 60 cubic cm.
Tip: review any topic that still feels tricky before moving to Grade 5. Strong foundations in place value, fractions, and geometry will support every new concept ahead.
