## Grade 2 Mathematics Topics and Sub-topics

**NUMBER SENSE**

1. Say the number sequence 0 to 100 by:

• 2s, 5s and 10s, forward and backward, using starting points that are multiples of 2, 5 and 10 respectively

• 10s, using starting points from 1 to 9

• 2s, starting from 1.

2. Demonstrate if a number (up to 100) is even or odd.

3. Describe order or relative position, using ordinal numbers (up to tenth).

4. Represent and describe numbers to 100, concretely, pictorially and symbolically.

5. Compare and order numbers up to 100.

6. Estimate quantities to 100, using referents.

7. Illustrate, concretely and pictorially, the meaning of place value for numerals to 100.

8. Demonstrate and explain the effect of adding zero to, or subtracting zero from, any number.

9. Demonstrate an understanding of addition (limited to 1- and 2-digit numerals) with answers to 100 and the corresponding subtraction by:

• using personal strategies for adding and subtracting with and without the support of manipulatives

• creating and solving problems that involve addition and subtraction

• using the commutative property of addition (the order in which numbers are added does not affect the sum)

• using the associative property of addition (grouping a set of numbers in different ways does not affect the sum)

• explaining that the order in which numbers are subtracted may affect the difference.

10. Apply mental mathematics strategies, such as:

• using doubles

• making 10

• one more, one less

• two more, two less

• building on a known double

• thinking addition for subtraction for basic addition facts and related subtraction facts to 18.

**PATTERNS AND RELATIONS**

Patterns • Use patterns to describe the world and to solve problems.

Variables and Equations • Represent algebraic expressions in multiple ways.

**SHAPE AND SPACE**

Measurement • Use direct and indirect measurement to solve problems.

3-D Objects and 2-D Shapes

• Describe the characteristics of 3-D objects and 2-D shapes, and analyze the relationships among them.

Transformations

• Describe and analyze position and motion of objects and shapes.

**STATISTICS AND PROBABILITY**

Data Analysis • Collect, display and analyze data to solve problems.

Chance and Uncertainty • Use experimental or theoretical probabilities to represent and solve problems involving uncertainty.
