1. Numbers and Calculations · To help pupils understand the meaning and the representations of numbers, and extend their ability to use numbers.

1. What Multiplication Means: Interpret products of whole numbers (e.g. 5 × 7 as the total number of objects in 5 groups of 7)
2. Numbers to 10,000: Identify, represent, and estimate numbers up to 10,000 using different representations
3. Tenths (age 8+): Count up and down in hundredths; recognise that hundredths arise when dividing an object by 100 or dividing tenths by 10
4. Understanding fractions: Write simple fractions (e.g. 1/2 of 6 = 3) and recognise the equivalence of 2/4 and 1/2

2. Numbers and Calculations · To help pupils deepen their understanding of addition and subtraction, and extend their ability to use the calculations.

1. Adding and subtracting (age 7+): Add and subtract numbers with up to three digits using formal written methods of columnar addition and subtraction
2. Adding and subtracting (age 8+): Add and subtract numbers with up to four digits using formal written methods of columnar addition and subtraction
3. Adding two two-digit numbers: Add and subtract two two-digit numbers using concrete objects, pictorial representations, and mental methods
4. Money Addition & Subtraction: Solve simple money problems involving addition and subtraction, including giving change

3. Quantities and Measurements · To help pupils understand the meaning of units and measurements of length and measure the length.

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
2. Calculating with measurements: Measure, compare, add, and subtract lengths (m/cm/mm), mass (kg/g), and volume/capacity (l/ml) using standard units
3. Estimating Lengths: Estimate lengths using units of inches, feet, centimetres, and metres

4. Quantities and Measurements · To help pupils understand the meaning of units and measurements of volume and measure the volume.

1. Choosing measurement units: Choose and use appropriate standard units to measure length (m/cm), mass (kg/g), temperature (°C), and capacity (litres/ml) to the nearest appropriate unit
2. 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

5. Quantities and Measurements · To help pupils understand time and use it.

1. Comparing Time Durations: Compare durations of events and calculate the time taken by particular events or tasks

6. Geometrical Figures · Through activities such as observing and composing the shapes of objects, to help pupils pay attention to the elements that compose geometrical figures, and understand geometrica

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

7. Mathematical Relations

1. Representing Addition and Subtraction: Represent addition and subtraction using objects, drawings, and mental images
2. Connecting maths to real life: Represent real-world problems with number sentences, bar models, or diagrams, and interpret the mathematical result back in context
