Grade 2 Math
10 units matched to the NWT Curriculum.
Big Ideas
- Numbers to 100 represent quantities that can be decomposed into 10s and 1s.
- Development of computational fluency in addition and subtraction with numbers to 100 requires an understanding of place value.
- The regular change in increasing patterns can be identified and used to make generalizations.
- Objects and shapes have attributes that can be described, measured, and compared.
- Concrete graphs help us to compare and interpret data and show one-to-one correspondence.
Units
Unit 1
Tens & Ones
Seeing 47 as 4 tens and 7 ones. This place-value idea underpins all Grade 2 adding and subtracting.
Learning standard: Number concepts to 100
Unit 2
Bigger or Smaller
Comparing and ordering numbers, using <, > and =, and noticing numbers close to 50.
Learning standard: Benchmarks of 25, 50 and 100; symbolic representation of equality and inequality
Unit 3
Facts to 20
Fluent facts to 20 using strategies like making ten and thinking addition to subtract.
Learning standard: Addition and subtraction facts to 20 (emerging computational fluency); change in quantity to 20
Unit 4
Adding to 100
Two-digit adding and subtracting by working with tens and ones, including making a new ten.
Learning standard: Addition and subtraction to 100
Unit 5
Patterns
Finding the repeating core of a pattern and describing how increasing patterns grow (skip counting).
Learning standard: Repeating and increasing patterns
Unit 6
Coins
Counting nickels, dimes, quarters and loonies to 100¢, and talking about spending and saving.
Learning standard: Financial literacy: coin combinations to 100 cents, and spending and saving
Unit 7
Measuring
Measuring with a ruler from zero and choosing between centimetres and metres.
Learning standard: Direct linear measurement, using standard units (centimetres, metres)
Unit 8
Shapes
Describing shapes by their sides, corners (vertices) and faces, and spotting 3D shapes in real life.
Learning standard: Multiple attributes of 2D shapes and 3D objects
Unit 9
Graphs
Reading picture graphs: how many, which has the most or fewest, and how many more.
Learning standard: Pictorial representation of concrete graphs, using one-to-one correspondence
Unit 10
Likely or Not
Using words like certain, likely, unlikely and impossible to describe everyday events and spinners.
Learning standard: Likelihood of familiar life events, using comparative language
