The Ontario Grade 5 math curriculum: what your child learns

Grade 5 is a fractions, decimals and percents year. Numbers go up to 100 000, decimals to hundredths, and kids see how 3/4, 0.75 and 75% are the same amount. Multiplication moves to two digits by two digits, and algebra adds expressions with letters.

The big ideas in Grade 5

  • Fractions to twelfths (including improper fractions and mixed numbers), decimals to hundredths, and percents
  • Multiplication facts to 12 × 12, two-digit by two-digit multiplication, and dividing by two-digit numbers
  • Adding and subtracting fractions with the same denominator
  • Evaluating expressions like 4n + 3, and solving equations up to 100
  • Area of triangles and parallelograms, protractors, and sales tax, budgets and unit rates

The curriculum lists 51 specific expectations for Grade 5, grouped into five strands. Here is each strand in plain language, with the kind of homework you’re likely to see. Every example comes with a hint instead of the answer, the way Spark would help.

Number

Your child works with numbers to 100 000, fractions from halves to twelfths (including improper fractions and mixed numbers), and decimals to hundredths, and connects fractions, decimals and whole-number percents. They recall facts to 12 × 12, multiply two-digit by two-digit numbers with the area model and a written method, divide three-digit numbers by two-digit numbers, add and subtract fractions with like denominators, and work with equivalent ratios and rates.

Typical homework, with a hint

HomeworkWrite 3/4 as a decimal and as a percent.

A hint, not the answerHow many hundredths is 3/4 the same as? What does “percent” mean?

HomeworkCalculate 23 × 14.

A hint, not the answerTry the area model: split 23 into 20 + 3 and 14 into 10 + 4. How many smaller rectangles do you get?

HomeworkCalculate 2/7 + 3/7.

A hint, not the answerThe denominators are the same. What does that tell you about the size of the pieces?

Algebra

Patterns can now shrink as well as grow. Kids translate between words and algebraic expressions (“3 more than a number” becomes n + 3), evaluate expressions by substituting a value, solve equations with whole numbers up to 100, and solve one-step inequalities. Code uses conditional statements (“if this, then that”).

Typical homework, with a hint

A hint, not the answerPut 5 where the n is. What does 4n mean?

HomeworkWrite an expression for “6 less than a number”.

A hint, not the answerPick a letter for the number. Are you adding 6 or taking 6 away?

  • Reading and changing codeC3.2

    Reads and changes existing code with conditions and other control structures, and describes how the changes affect what happens.

Math modelling (C4): Turns a real-life situation into math (a model) to represent it, analyse it, make predictions and understand it better.

Data

Kids learn why a good sample matters, organise data in relative-frequency tables, choose graphs (including stacked-bar graphs), and spot misleading graphs. They find the mean, median and mode with decimals too. Probability is written as a fraction, and they compare what should happen (theoretical) with what did happen (experimental).

Typical homework, with a hint

HomeworkA spinner has 8 equal sections and 3 are blue. What is the probability of landing on blue?

A hint, not the answerHow many sections are there in total? How many of them are blue? How could you write that as a fraction?

HomeworkA bar graph’s scale starts at 90 instead of 0. Why might that be misleading?

A hint, not the answerCompare how tall the bars look with the actual numbers. Does a small difference look big?

What your child learns in Data

  • Sampling techniquesD1.1

    Explains why the way you choose a sample matters, so that the data you collect fairly represents the whole group.

  • Relative-frequency tablesD1.2

    Collects data about a group (using a sample when needed) to answer questions, and organizes it in relative-frequency tables (showing each count as a fraction, decimal or percent of the total).

  • Choosing the right graphD1.3

    Picks the best type of graph for a set of data, including stacked-bar graphs, gives it a title, labels, a suitable scale and the data source, and explains why that graph fits.

  • Making an infographicD1.4

    Makes an infographic that tells the story of a data set, using relative-frequency tables, stacked-bar graphs and any other useful information.

  • Theoretical vs experimental probabilityD2.2

    Works out and compares the theoretical probability of an event (what should happen) and the experimental probability (what happens when you try it).

Spatial Sense

Geometry covers types of triangles, congruent shapes, and drawing top, front and side views. Kids plot points with different scales and do translations, reflections and rotations up to 180°. In measurement they convert metric units (like metres to centimetres), use a protractor, find the area of triangles and parallelograms, and see that shapes with the same area can have different perimeters.

Typical homework, with a hint

HomeworkFind the area of a triangle with a base of 10 cm and a height of 6 cm.

A hint, not the answerHow is this triangle related to a rectangle with the same base and height?

A hint, not the answerHow many centimetres are in 1 metre? So how many in 3 metres, and in half a metre?

  • Same area, different perimeterE2.6

    Shows that two shapes can cover the same area but have different perimeters, and solves problems about it.

Financial Literacy

Money gets real: how money moves between people and businesses, totals with sales tax, simple budgets, credit and debt, unit rates to find the best value, and the kinds of taxes collected by different levels of government in Canada.

Typical homework, with a hint

HomeworkA 2 L bottle of juice costs $3.00 and a 500 mL bottle costs $1.00. Which is the better deal?

A hint, not the answerHow many 500 mL bottles make 2 L? What would that many small bottles cost?

HomeworkA game costs $20 plus 13% sales tax. What is the total?

A hint, not the answerWhat is 10% of $20? What is 1%, and so 3%? How can you put those together?

What your child learns in Financial Literacy

  • How money movesF1.1

    Describes several ways money moves between people, organizations and businesses (like e-transfers, cheques or cards).

  • Costs with sales taxF1.2

    Estimates and works out what several items cost together, with prices in dollars and cents and sales tax added, using different strategies.

  • Making a budgetF1.3

    Plans simple sample budgets for different situations of earning and spending money.

  • Credit and debtF1.4

    Explains what credit and debt are, and how each one can affect money decisions.

    Works out unit rates (like the price per 100 g) for different goods and services, and finds which is the best value.

  • Taxes in CanadaF1.6

    Describes the kinds of taxes collected by the federal, provincial and local governments in Canada, and how that money pays for community services.

Social-emotional learning and math processes

The Ontario curriculum also has a strand A that runs through all the others. It’s about how kids approach math: managing frustration, keeping at a hard problem, and using the mathematical processes (such as problem solving, reasoning, connecting, representing and communicating). It has no homework of its own, but it’s exactly what a patient, hint-based tutor helps build.

How to help with Grade 5 math at home

  • Use money to make decimals and percents concrete: 25¢ is 0.25 of a dollar and 25% of a dollar.
  • For fractions, draw it. A quick sketch of pieces clears up most confusion.
  • Ask “is your answer reasonable?” after every calculation. Estimating first catches big mistakes.
  • Let your child compare unit prices at the grocery store.

How Astuzo helps with Grade 5 math

In Grade 5 many mistakes hide in the middle of a long calculation. When an answer is off, Spark doesn’t just say “wrong”. It asks your child to walk through their steps and helps them find the slip themselves, which is how kids learn to check their own work.

You set your child’s grade once, and Spark pitches every hint at that level. You get a short email each evening they use it, showing what they worked on. See how Astuzo works.
