Grade 5 Math: how to help at home
What your child learns in Grade 5 math in the BC Curriculum, and simple things to try at home.
The Big Ideas this year
- Numbers describe quantities that can be represented by equivalent fractions.
- Computational fluency and flexibility with numbers extend to operations with larger (multi-digit) numbers.
- Identified regularities in number patterns can be expressed in tables.
- Closed shapes have area and perimeter that can be described, measured, and compared.
- Data represented in graphs can be used to show many-to-one correspondence.
Easy ways to practise math at home
- Look for fractions, decimals and percentages in sale signs, sports statistics and recipes.
- Ask your child to explain a problem to you as if you were the student.
- Estimate first (the bill, the trip time), then check with a calculator.
- Keep a tricky-problems list and revisit it every few days instead of re-doing everything.
What each unit covers
Numbers to a Million
Place value to 1 000 000: digit values, standard and expanded form, number words, rounding, ordering, and using benchmarks like 500 000 on a number line.
Add & Subtract
Adding and subtracting numbers up to 1 000 000 with regrouping (including across zeros), estimating by rounding, and mental math such as compensation (adding 4999 as 5000 − 1).
Multiply
Multiplying 2- and 3-digit numbers using area models and partial products, patterns with 10, 100 and 1000, doubling and halving, and estimating products by rounding.
Divide
Dividing 2- and 3-digit numbers, finding remainders and deciding what they mean in a story (round up for buses, drop the extra for full bags), and estimating with friendly numbers.
Equivalent Fractions
Making and recognizing equivalent fractions (2/3 = 8/12), simplifying, comparing and ordering fractions, and judging whether a fraction is close to 0, 1/2 or 1.
Decimals
Reading, writing, comparing and rounding decimals to thousandths, linking decimals to fractions out of 10, 100 and 1000, and adding and subtracting decimals in real situations.
Patterns & Equations
Describing growing and shrinking patterns with rules and expressions like 3n + 1, using input–output tables, and solving one-step equations such as n + 37 = 92 or 6 × n = 54.
Area & Perimeter
Finding the area and perimeter of squares and rectangles, working backwards to a missing side, and discovering that shapes with the same area can have different perimeters (and vice versa).
Time & Duration
Working out how long events last, finding end and start times, reading schedules, and converting between seconds, minutes, hours, days and weeks.
Prisms, Pyramids & Moves
Naming and classifying prisms and pyramids by their bases, counting faces, edges and vertices, and describing single transformations: translations (slides), reflections (flips) and rotations (turns).
Graphs & Chance
Reading double bar graphs where each square stands for several items (many-to-one), comparing two sets of data, and describing the probability of single outcomes with spinners, marbles, dice and coins.
Money & Budgets
Making change for purchases up to $1000, counting bills and coins, estimating whether there is enough money, and building simple budgets and savings plans.
What the report card levels look like at home
- Emerging
- Just getting started with this idea. Short, regular practice with lots of support helps most.
- Developing
- Understands parts of it and is building confidence. Keep practising the tricky parts.
- Proficient
- Has it! Mixed review now and then keeps it strong.
- Extending
- Applies it confidently, even in new or harder situations. Try challenge mode and real-life problems.
Your child’s teacher decides the level on the report card. Read the BC report card guide.
Common questions
How can I help my Grade 5 child with math?
Look for fractions, decimals and percentages in sale signs, sports statistics and recipes. Ask your child to explain a problem to you as if you were the student. Keep sessions short, about 10 to 15 minutes, and stop on a success.
