  1. Measuring mass and weight: Measure and begin to record mass/weight using non-standard and standard units

6. Shape and Space · Demonstrate understanding of nonstandard units for linear measurement by: • describing the choice and appropriate use of nonstandard units • estimating • measuring • comparing and an

  1. 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

7. Patterns and Relations · Demonstrate understanding of equality and inequality concretely and pictorially (0 to 100) by: • relating equality and inequality to balance • comparing sets • recording equal

  1. Connecting Representations: Move between real-world situations, drawings, and number sentences, explaining how each representation connects to the others (quantitative reasoning)
  2. Patterns & Sequences: Order and arrange combinations of mathematical objects in patterns and sequences
  3. 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
  4. Comparing and ordering measurements: Compare and order lengths, mass, and capacity and record results using >, <, and =

8. Patterns and Relations · Demonstrate understanding of increasing patterns by: • describing • reproducing • extending • creating patterns using manipulatives, pictures, sounds, and actions (numbers to

  1. Shape patterns: Look for and use mathematical structure: apply properties of operations, place-value patterns, and relationships between shapes to solve problems efficiently
  2. 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. Number · Demonstrate understanding of addition (limited to 1 and 2-digit numerals) with answers to 100 and the corresponding subtraction by: • representing strategies for adding and subtracting concre
