Unit 5
Multiplication
Understanding multiplication as equal groups, arrays, repeated addition and skip counting. Easier sets use 2s, 5s and 10s; stretch sets go beyond 5 × 5.
Approved guide: Alberta Mathematics K–9 (2007), Number · multiplication as repeated addition, arrays and equal groups
Unit 6
Division
Understanding division as sharing fairly and as making equal groups, and using multiplication facts to divide (3 × 4 = 12, so 12 ÷ 3 = 4).
Approved guide: Alberta Mathematics K–9 (2007), Number · division as sharing and grouping
Unit 7
Fractions
Naming fractions of a shape, a set and a number line, knowing what the top and bottom numbers mean, and comparing fractions by the size of their parts.
Approved guide: Alberta Mathematics K–9 (2007), Number · fractions as parts of a whole or a set
Unit 8
Patterns & Equations
Extending increasing and decreasing patterns, describing pattern rules in words and tables, and solving one-step equations like ☐ + 8 = 23.
Approved guide: Alberta Mathematics K–9 (2007), Patterns and Relations · increasing and decreasing patterns, and one-step equations with a symbol
Unit 9
Time
Telling time on an analog clock, working out start and end times, and knowing how seconds, minutes, hours, days, weeks, months and years relate.
Approved guide: Alberta Mathematics K–9 (2007), Shape and Space · the passage of time, and seconds, minutes, hours, days and months
Unit 10
Measuring
