Grade 1 Math
10 units matched to the NWT Curriculum. Kids see this subject as “Numbers”.
Big Ideas
- Numbers to 20 represent quantities that can be decomposed into 10s and 1s.
- Addition and subtraction with numbers to 10 can be modelled concretely, pictorially, and symbolically to develop computational fluency.
- Repeating elements in patterns can be identified.
- Objects and shapes have attributes that can be described, measured, and compared.
- Concrete items can be represented, compared, and interpreted pictorially in graphs.
Units
Unit 1
Numbers to 20
Counting, ordering and comparing numbers to 20, and seeing teen numbers as 1 ten and some ones.
Learning standard: Number concepts to 20
Unit 2
Make 10
Finding pairs that make 10 (like 6 + 4) with ten frames, fingers and stories. Making 10 is a key strategy for adding.
Learning standard: Ways to make 10
Unit 3
Adding
Adding to 20 with pictures, ten frames, number lines and short stories, using strategies like counting on, doubles and making 10.
Learning standard: Addition and subtraction to 20 (understanding of operation and process); change in quantity to 20
Unit 4
Take Away
Subtracting within 20 by counting back and thinking addition, and solving short take-away and compare stories.
Learning standard: Addition and subtraction to 20 (understanding of operation and process); change in quantity to 20, concretely and verbally
Unit 5
Equal or Not
Learning that = means "the same amount as" (not just "the answer is"), and using ≠ when two sides are different.
Learning standard: Meaning of equality and inequality
Unit 6
Patterns
Finding the repeating part (the core) of patterns like AB, ABB and ABBC, including patterns where colour and shape both change.
Learning standard: Repeating patterns with multiple elements and attributes
Unit 7
Measuring
Measuring length with paper clips and cubes, comparing longer and shorter, heavier and lighter, and seeing why same-size units matter.
Learning standard: Direct measurement with non-standard units (non-uniform and uniform)
Unit 8
Shapes
Naming and comparing 2D shapes by their sides and corners, and 3D objects by their faces and whether they roll or stack.
Learning standard: Comparison of 2D shapes and 3D objects
Unit 9
Coins
Knowing the values of Canadian nickels, dimes and quarters, counting small amounts, and trading coins of equal value.
Learning standard: Financial literacy: values of coins, and monetary exchanges
Unit 10
Graphs & Chance
Reading picture and bar graphs (how many, most, fewest, how many more) and talking about how likely everyday events are.
Learning standard: Concrete or pictorial graphs as a visual tool; likelihood of familiar life events
