Grade 4 Math
12 units matched to the NWT Curriculum.
Big Ideas
- Fractions and decimals are types of numbers that can represent quantities.
- Development of computational fluency and multiplicative thinking requires analysis of patterns and relations in multiplication and division.
- Regular changes in patterns can be identified and represented using tools and tables.
- Polygons are closed shapes with similar attributes that can be described, measured, and compared.
- Analyzing and interpreting experiments in data probability develops an understanding of chance.

Learning standard: Multiplication and division facts to 100 (introductory computational strategies)
Unit 4
Multiply & Divide
Multiplying and dividing 2- and 3-digit numbers by 1-digit numbers by splitting them by place value, plus remainders, estimating and word problems.
Learning standard: Multiplication and division of two- or three-digit numbers by one-digit numbers
Unit 5
Fractions
Naming fractions from pictures and number lines, comparing fractions with the same top or bottom number, using 1/2 as a benchmark, and finding equal fractions.
Learning standard: Ordering and comparing fractions
Unit 6
Decimals
Tenths and hundredths as decimals, linking them to fractions, placing and comparing them on number lines, and adding and subtracting decimals by lining up the decimal points.
Learning standard: Decimals to hundredths; addition and subtraction of decimals to hundredths
Unit 7
Patterns & Tables
Extending increasing and decreasing number patterns, naming pattern rules, finding rules in input/output tables, and describing how two quantities are related.
Learning standard: Increasing and decreasing patterns, using tables and charts; algebraic relationships among quantities
Unit 8
Equations
Solving one-step equations with a box or letter for the unknown, using all four operations, and matching equations to word problems.
Learning standard: One-step equations with an unknown number, using all operations
Unit 9
Telling Time
Reading analog clocks to the minute, switching between 12-hour (a.m./p.m.) and 24-hour time, and working out how long events last.
Learning standard: How to tell time with analog and digital clocks, using 12- and 24-hour clocks
Unit 10
Polygons & Perimeter
Telling regular polygons (all sides and angles equal) from irregular ones, finding lines of symmetry, and measuring perimeter around regular and irregular shapes.
Learning standard: Regular and irregular polygons; line symmetry; perimeter of regular and irregular shapes
Unit 11
Graphs & Chance
Reading bar graphs and pictographs where one picture can stand for many, and predicting and interpreting the results of spinner, dice and coin experiments.
Learning standard: One-to-one correspondence and many-to-one correspondence, using bar graphs and pictographs; probability experiments
Unit 12
Money & Change
Counting bills and coins, making change from up to $100, adding prices, and simple money decisions like comparing deals, budgeting and saving.
Learning standard: Financial literacy: monetary calculations, including making change with amounts to 100 dollars and making simple financial decisions
