1. Comparing groups: more or fewer: Compare two groups of objects to determine which has more, fewer, or whether they are equal, using matching and counting strategies
2. Counting objects to 20: Count a set of objects to answer 'how many?' for sets up to 20 (arranged in lines, arrays, circles, or scattered)
3. Multiplication as repeated addition (age 6+): Solve problems involving multiplication and division using arrays, repeated addition, mental methods, and known facts
4. Adding numbers: Add up to four two-digit numbers using strategies based on place value and properties of operations
5. Addition and subtraction word problems: Solve addition and subtraction word problems within 10 using objects or drawings
6. Adding two two-digit numbers: Add and subtract two two-digit numbers using concrete objects, pictorial representations, and mental methods
7. Mental and written addition and subtraction: Solve addition and subtraction problems using mental and written methods, including problems involving numbers, quantities, and measures
8. Sorting into categories: Classify objects into given categories, count the number in each category, and sort the categories by count
9. Patterns & Sequences: Order and arrange combinations of mathematical objects in patterns and sequences
10. Positional Language: Describe the position of objects using terms such as above, below, beside, in front of, behind, next to
11. 3-D shapes: Recognise and name common 3-D shapes (cubes, cuboids, pyramids, spheres, cylinders, cones)
12. 2-D shapes: Recognise and name common 2-D shapes (circles, triangles, rectangles including squares)
13. Comparing Lengths & Heights: Compare two objects directly by length or height and describe the difference using language such as long, short, tall, longer, shorter, taller, double, half
14. Comparing durations: Use comparative language for time: quicker, slower, earlier, later
15. Ordering Events in Time: Sequence events in chronological order using language such as before, after, next, first, today, yesterday, tomorrow, morning, afternoon, evening
16. Days, Weeks, Months & Years: Recognise and use language relating to dates, including days of the week, weeks, months, and years
17. Likelihood Language: Use probability language to describe and compare the likelihood of everyday events using words such as certain, likely, even chance, unlikely, impossible
18. Pictograms and tally charts: Interpret and construct simple pictograms, tally charts, block diagrams, and simple tables
19. Sorting Data into Categories: Organise and represent data with up to three categories by counting objects in each category and sorting categories by quantity
