0 of 15 concepts ready to learn · Markdown, for your AI

1. Geometry · Reason with shapes and their attributes.

1. Understanding angles: Recognise angles as a property of shape or a description of a turn

2. Measurement and Data · Represent and interpret data.

1. Measuring length (age 7+): Measure the length of an object by selecting and using appropriate tools such as rulers, yardsticks, metre sticks, and measuring tapes
2. Measuring & Plotting Lengths: Generate measurement data by measuring lengths to the nearest whole unit and display the data on a line plot
3. Picture & Bar Graphs: Draw a picture graph and a bar graph (with single-unit scale) to represent a data set with up to four categories; solve put-together, take-apart, and compare problems using information presented in a bar graph

3. Measurement and Data · Solve problems involving measurement and estimation of intervals of time, liquid volumes, and masses of objects.

1. Measuring Liquids & Masses: Measure and estimate liquid volumes and masses of objects using grams, kilograms, and litres; solve one-step word problems involving mass or volume
2. Estimating answers (age 7+): Estimate and read time with increasing accuracy to the nearest minute; record and compare time in terms of seconds, minutes, and hours

4. Number and Operations – Fractions · Develop understanding of fractions as numbers.

1. Fraction Addition Concepts: Understand addition and subtraction of fractions as joining and separating parts; decompose a fraction into a sum of fractions with the same denominator in more than one way
2. Fractions on a number line: Recognise and use fractions as numbers: place unit fractions and non-unit fractions with small denominators on a number line
3. Fractions of a whole: Understand a fraction 1/b as the quantity formed by 1 part when a whole is partitioned into b equal parts; understand a/b as a parts of size 1/b

5. Number and Operations in Base Ten · Use place value understanding and properties of operations to perform multi-digit arithmetic, using a variety of strategies.

1. Adding numbers: Add up to four two-digit numbers using strategies based on place value and properties of operations
2. Numbers to 10,000: Identify, represent, and estimate numbers up to 10,000 using different representations

6. Operations and Algebraic Thinking · Solve problems involving the four operations and identify and explain patterns in arithmetic.

1. Patterns in Times Tables: Identify arithmetic patterns (including patterns in the addition table or multiplication table) and explain them using properties of operations
2. Multi-Step Problem Solving: Make sense of multi-step problems involving four operations, fractions, and area/volume by identifying sub-steps, choosing a strategy, and monitoring progress

7. Operations and Algebraic Thinking · Multiply and divide within 100.

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

8. Operations and Algebraic Thinking · Represent and solve problems involving multiplication and division.

1. What Multiplication Means: Interpret products of whole numbers (e.g. 5 × 7 as the total number of objects in 5 groups of 7)
