1. Data and Statistics · Represent and interpret data.

1. Pictograms and tally charts: Interpret and construct simple pictograms, tally charts, block diagrams, and simple tables

2. Geometry and Measurement · Measure lengths in non-standard units.

1. Measuring length: Order three objects by length and compare the lengths of two objects indirectly using a third object
2. Comparing lengths by measuring: Measure to determine how much longer one object is than another, expressing the length difference in terms of a standard length unit
3. Measuring with different units: Measure the length of an object using two different length units and describe how the measurements relate to the size of the unit chosen

3. Geometry and Measurement · Reason with shapes and their attributes.

1. Halves & Quarters of Shapes: Partition circles and rectangles into two and four equal shares and describe them using the words halves, fourths, and quarters
2. Composing Shapes: Compose two-dimensional shapes (rectangles, squares, trapezoids, triangles, half-circles, quarter-circles) to create composite shapes, and compose new shapes from the composite shape
3. Angles in triangles (age 6+): Distinguish defining attributes of shapes (e.g. triangles are closed and three-sided) from non-defining attributes (e.g. colour, orientation, overall size)

4. Number Sense and Operations in Base Ten · Use place value understanding to add and subtract.

1. Adding numbers: Add up to four two-digit numbers using strategies based on place value and properties of operations
2. Subtracting multiples of 10: Subtract multiples of 10 (10–90) from multiples of 10 using place value strategies

5. Number Sense and Operations in Base Ten · Understand place value of two-digit numbers.

1. The two digits of a two-digit number: Understand that the two digits of a two-digit number represent amounts of tens and ones
2. Comparing and ordering numbers: Compare and order two-digit numbers using the symbols >, =, and <, based on place value understanding

6. Relationships and Algebraic Thinking · Add and subtract within 20.

1. Fluent adding and subtracting within 10: Fluently add and subtract within 10
2. Fluent adding and subtracting within 20: Fluently add and subtract within 20 using mental strategies; know from memory all sums of two one-digit numbers

7. Relationships and Algebraic Thinking · Represent and solve problems involving addition and subtraction.

1. What the equals sign means: Understand the meaning of the equal sign as 'is the same as' and determine if equations are true or false
2. Addition and subtraction within 20: Add and subtract within 20 using strategies such as making ten, decomposing a number leading to ten, and using known facts
3. Addition and subtraction word problems: Solve addition and subtraction word problems within 10 using objects or drawings
