1. Geometry & Measurement · Use time and money in real-world and mathematical situations.

1. Halves and quarters (age 7+): Solve word problems involving dollar bills, quarters, dimes, nickels, and pennies, using $ and ¢ symbols appropriately
2. 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
3. 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
4. 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

2. Geometry & Measurement · Understand length as a measurable attribute; use tools to measure length.

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 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. 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. Geometry & Measurement · Identify, describe and compare basic shapes according to their geometric attributes.

1. 3-D shapes: Recognise and name common 3-D shapes (cubes, cuboids, pyramids, spheres, cylinders, cones)
2. 2-D shapes: Recognise and name common 2-D shapes (circles, triangles, rectangles including squares)
3. Edges, vertices, and faces: Identify and describe properties of 3-D shapes including the number of edges, vertices, and faces

4. Algebra · Use number sentences involving addition, subtraction and unknowns to represent and solve real-world and mathematical problems; create real-world situations corresponding to number sentences.

1. Connecting maths to real life: Represent real-world problems with number sentences, bar models, or diagrams, and interpret the mathematical result back in context
2. Connecting Representations: Move between real-world situations, drawings, and number sentences, explaining how each representation connects to the others (quantitative reasoning)

5. Algebra · Recognize, create, describe, and use patterns and rules to solve real-world and mathematical problems.

1. Patterns & Sequences: Order and arrange combinations of mathematical objects in patterns and sequences

6. Number & Operation · Demonstrate mastery of addition and subtraction basic facts; add and subtract one- and two-digit numbers in real-world and mathematical problems.

1. Adding numbers: Add up to four two-digit numbers using strategies based on place value and properties of operations
2. Adding two two-digit numbers: Add and subtract two two-digit numbers using concrete objects, pictorial representations, and mental methods

7. Number & Operation · Compare and represent whole numbers up to 1000 with an emphasis on place value and equality.

1. Ordering Numbers to 1000: Compare and order numbers up to 1000 using >, =, and < symbols, based on place-value understanding
2. Representing Numbers: Identify, represent, and estimate numbers using different representations including the number line
3. Numbers to 10,000: Identify, represent, and estimate numbers up to 10,000 using different representations
4. Comparing Large Numbers: Order and compare numbers beyond 1000
5. Rounding to 10, 100, 1000: Round any number to the nearest 10, 100, or 1000
6. 10 or 100 More or Less: Find 10 or 100 more or less than a given number up to 1000
7. Place Value to 1000: Solve number problems and practical problems involving place value of numbers up to 1000
