1. Numbers and Calculations · Through activities such as counting the numbers of concrete objects, to help pupils understand the meaning of numbers and use numbers.

1. One-to-one counting: One-to-one correspondence when counting objects: each object is paired with exactly one number name
2. Sorting into categories: Classify objects into given categories, count the number in each category, and sort the categories by count
3. Representing numbers with objects: Represent numbers using objects, pictorial representations, and the number line
4. Division as equal sharing: Understand division as sharing equally into groups or as grouping (how many groups of a given size can be made)
5. Understanding fractions: Move fluently between real-world situations, diagrams, and symbolic equations involving three-digit numbers and fractions, explaining what each part represents

2. Numbers and Calculations · To help pupils understand the meaning of addition and subtraction and use the calculations.

1. Addition as combining or putting together two: Understand addition as combining or putting together two groups to find the total
2. Adding and subtracting: Add and subtract one-digit and two-digit numbers to 20, including zero
3. Adding and subtracting (age 7+): Add and subtract numbers with up to three digits using formal written methods of columnar addition and subtraction
4. Adding two two-digit numbers: Add and subtract two two-digit numbers using concrete objects, pictorial representations, and mental methods
5. Money Addition & Subtraction: Solve simple money problems involving addition and subtraction, including giving change

3. Quantities and Measurements · Through activities such as comparing sizes of concrete objects, to help pupils enrich their experiences that will form the foundation for understanding quantities and mea

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

4. Quantities and Measurements

1. 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

5. Geometrical Figures · Through activities such as observing and composing the shapes of familiar objects, to help pupils enrich their experiences that will form the foundation for understanding geometr

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
2. Positional Language: Describe the position of objects using terms such as above, below, beside, in front of, behind, next to

6. Mathematical Relations

1. Representing Addition and Subtraction: Represent addition and subtraction using objects, drawings, and mental images
