Mathematics, Grade 2

Unit 1: Number

Numbers up to 200: reading and building them, comparing and ordering them, counting and estimating groups of things, telling even from odd, sharing fairly, and adding, subtracting, multiplying, and dividing.

• Reading, showing, building, and breaking apart numbers to 200
• Comparing and ordering numbers to 200
• Estimating and checking by counting to 200
• Counting to 200 by 20s, 25s, and 50s
• What makes a number even or odd

• Sharing fairly among 2, 3, 4, and 6 friends
• One third is the same as two sixths

• How addition, subtraction, multiplication, and division connect
• Addition and subtraction facts to 20
• Mental math to add and subtract within 50

• Using objects, drawings, and equations to solve number stories

• Multiplication as repeated equal groups
• Division as sharing up to 12 items equally

Unit 2: Algebra

Noticing, making, and extending patterns with shapes and numbers; telling what changes and what stays the same; and writing and reading step-by-step and at-the-same-time code.

• Spotting patterns in geometric designs
• Making and re-showing patterns with shapes and numbers
• Finding the pattern rule to extend and predict with shapes and numbers
• Using patterns to show how numbers to 100 relate

• Noticing when a symbol is a variable
• Making addition and subtraction expressions equal
• Finding equal ways to make the same number to 100

• Writing and running code with things happening at the same time
• Reading and changing code with things happening at the same time

Unit 3: Data

Sorting data by two features, collecting and showing it in more kinds of graphs, finding the mode, asking and answering questions about it — and describing likelihood, including complementary events.

• Sorting data by two features with Venn and Carroll diagrams
• Collecting data about two things and using two-way tally tables
• Showing data with line plots and bar graphs
• Finding the mode of a data set
• Asking and answering questions about data in logic diagrams, line plots, and bar graphs

• Describing likelihood, including events that cannot both happen
• Predicting if the mode will match in a different group

Unit 4: Spatial Sense

Sorting 2D shapes by sides, angles, and symmetry; composing and decomposing shapes; checking for congruence; making simple maps; describing positions and movements; and measuring length and time.

• Sorting 2D shapes by sides, angles, and symmetry
• Building and breaking apart shapes without changing their area
• Checking if shapes match exactly (congruent)

• Making and reading simple maps
• Describing where several things are and how to move between them

• Measuring length with non-standard units
• Centimetres and metres, with benchmarks to estimate
• Measuring and drawing lengths in centimetres and metres
• Describing how long something takes using units of time

Unit 5: Financial Literacy

Showing the same amount of Canadian money in different ways.

• Showing the same amount of money with different coins and bills
