About Year 1 mathematics
In Stage 1, learners following Cambridge Primary Mathematics work with numbers to 100, place value in tens and ones, addition and subtraction within 20, halves and quarters, money, time and shapes.

Year 1 maths questions
What maths do Stage 1 learners study?
Stage 1 maths usually focuses on numbers to 100, adding and subtracting within 20, money, and telling the time. Key skills include learning to count, read and write numbers to 100 and understand tens and ones; add and subtract within 20, including number bonds to 10; recognise halves and quarters of shapes and quantities.
What should my child know before starting Stage 1 maths?
No previous maths practice is needed. It helps if learners can count to 20, recognise numbers and add small groups of objects.
How often should my child practise Stage 1 maths?
Short, regular sessions work best: about 10 to 15 minutes, three or four times a week. Start with the current class topic and revisit earlier topics for revision.
