1. Measurement & Data Reasoning · Use appropriate tools to measure, order, and compare intervals of length and time, as well as denominations of money to solve real-life, mathematical problems and analyz

  1. Working with money: Model real-world problems involving measurement, money, and time by choosing appropriate representations and interpreting results in context
  2. Halves and quarters (age 7+): Solve word problems involving dollar bills, quarters, dimes, nickels, and pennies, using $ and ¢ symbols appropriately
  3. Telling Time: Hours and Half Hours: Tell the time to the hour and half past the hour, and draw clock hands to show these times
  4. Telling Time: Minutes: Tell and write the time to five minutes, including quarter past and quarter to, and draw clock hands to show these times
  5. Measuring length: Order three objects by length and compare the lengths of two objects indirectly using a third object
  6. 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
  7. 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

2. Geometric & Spatial Reasoning · Compose shapes, analyze the attributes of shapes, and relate their parts to the whole.

  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. 2-D shapes: Recognise and name common 2-D shapes (circles, triangles, rectangles including squares)
  3. 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
  4. Sorting 2-D and 3-D shapes: Compare and sort common 2-D and 3-D shapes and everyday objects by their properties

3. Patterning & Algebraic Reasoning · Identify, describe, extend, and create repeating patterns, growing patterns, and shrinking patterns found in real-life situations.

  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

4. Numerical Reasoning · Use concrete models, the base ten structure, and properties of operations to add and subtract within 100.

  1. Addition and subtraction within 1000: Add and subtract within 1000 using concrete models, drawings, and strategies based on place value; understand composing and decomposing tens and hundreds
  2. 10 More or 10 Less: Mentally find 10 more or 10 less than a given two-digit number without counting

5. Numerical Reasoning · Explain the relationship between addition and subtraction and apply the properties of operations to solve real-life addition and subtraction problems within 20.

  1. 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
  2. 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
  3. Unknown in Addition & Subtraction: Determine the unknown whole number in an addition or subtraction equation relating three whole numbers
  4. 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
  5. Inverse: addition undoes subtraction: Recognise and use the inverse relationship between addition and subtraction to check calculations and solve missing-number problems
  6. Connecting Representations: Move between real-world situations, drawings, and number sentences, explaining how each representation connects to the others (quantitative reasoning)

6. Numerical Reasoning · Extend the count sequence to 120. Read, write, and represent numerical values to 120 and compare numerical values to 100.

  1. Reading and writing numbers to 100: Read and write numerals from 0 to 100
  2. Reading and writing numbers to 120: Count to 120 starting at any number less than 120; read and write numerals to 120
  3. The two digits of a two-digit number: Understand that the two digits of a two-digit number represent amounts of tens and ones

7. Mathematical Practices · Display perseverance and patience in problem-solving. Demonstrate skills and strategies needed to succeed in mathematics, including critical thinking, reasoning, and effective

  1. Justifying mathematical reasoning: Construct and follow multi-step mathematical arguments; identify errors in reasoning and explain why a method works or does not work
  2. Precise Maths Communication: Communicate with mathematical precision: use correct vocabulary, specify units, and use symbols accurately
  3. Making Sense of Problems: Make sense of a problem by identifying what is being asked, choosing concrete objects or pictures to represent the situation, and explaining a pathway to the solution
