1. Data Analysis · With guidance, collect data from a simple survey or collaborative investigation; organize data into appropriate single-unit bar graphs, pictographs, and/or tables and draw conclusions

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

2. Measurement · Identify the value of a penny, nickel, dime, and a collection of pennies, nickels, and dimes.

  1. Coin Values: Recognise and know the value of different coins and notes

3. Measurement · Tell and write time to the nearest half-hour and relate time to events (before/after, shorter/longer) using analog clocks. Explain how to read hours and minutes using digital clocks. (E)

  1. Telling time to the minute (age 7+): Tell and write time from analogue and digital clocks to the nearest five minutes, using a.m., p.m., and 12-hour and 24-hour notation

4. Measurement · Use direct comparison or a nonstandard unit to compare and order objects according to length, area, capacity, weight, and temperature. (E)

  1. Comparing and ordering measurements: Compare and order lengths, mass, and capacity and record results using >, <, and =
  2. Measuring length: Order three objects by length and compare the lengths of two objects indirectly using a third object

5. Geometry · Partition circles and rectangles into two and four equal parts; describe the parts using the words halves, fourths, and quarters; and use the phrases half of, fourth of, and quarter of. Des

  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

6. Geometry · Use two-dimensional shapes (e.g., rectangles, squares, trapezoids, triangles, half-circles, quarter-circles) or three-dimensional shapes (e.g., cubes, right rectangular prisms, right circul

  1. 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
  2. Building with 3-D Shapes: Compose three-dimensional shapes (cubes, right rectangular prisms, right circular cones, right circular cylinders) and create composite shapes; build new shapes from component shapes

7. Geometry · Distinguish between defining attributes of two- and three-dimensional shapes (e.g., triangles are closed and three-sided) versus non-defining attributes (e.g., color, orientation, overall s

  1. 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)

8. Computation and Algebraic Thinking · Create, extend, and give an appropriate rule for number patterns using addition within 100.

  1. Extending Table Patterns: Recognise and use repeated reasoning to generalise: extend multiplication table patterns, derive unknown facts from known ones, and describe rules for sequences

9. Computation and Algebraic Thinking · Using number sense and place value strategies, add within 100, including adding a two-digit number and a one-digit number, and adding a two-digit number and a mult

  1. Adding within 100: Add within 100 using strategies based on place value, including adding a two-digit and one-digit number, and a two-digit and a multiple of 10
  2. Adding numbers: Add up to four two-digit numbers using strategies based on place value and properties of operations

10. Computation and Algebraic Thinking · Solve real-world problems involving addition and subtraction within 20 in situations of adding to, taking from, putting together, taking apart, and comparing, with

  1. Addition and subtraction word problems: Solve addition and subtraction word problems within 10 using objects or drawings
  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

11. Computation and Algebraic Thinking · Demonstrate fluency with addition facts and the corresponding subtraction facts within 20. Use strategies such as counting on; making ten (e.g., 8 + 6 = 8 + 2 + 4

  1. 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
  2. Fluent addition and subtraction: Recall and use addition and subtraction facts to 20 fluently, and derive and use related facts up to 100

12. Number Sense · Use place value understanding to compare two two-digit numbers based on meanings of the tens and ones digits, recording the results of comparisons with the symbols > , = , and <. (E)

  1. Comparing and ordering numbers: Compare and order two-digit numbers using the symbols >, =, and <, based on place value understanding

13. Number Sense · Match the ordinal numbers (e.g., first, second, third) with an ordered set of up to 20 items.

  1. Counting objects to 20: Count a set of objects to answer 'how many?' for sets up to 20 (arranged in lines, arrays, circles, or scattered)
