These Year 1 maths worksheets cover the six areas young mathematicians work through in their first year of Key Stage 1: place value, addition and subtraction, early multiplication and division, fractions, measurement, and geometry. Each one targets specific objectives from the Year 1 programme of study, from identifying one more and one less than a number to recognising a quarter of a shape or quantity.
Because everything follows the England National Curriculum for mathematics, the vocabulary and difficulty match what pupils meet in class. Number work stays within the ranges expected of five and six year olds, and questions lean on the concrete and pictorial representations that Year 1 children need before moving to abstract calculation.
Teachers print these worksheets for whole-class practice, set them as short homework tasks, or use them in interventions with pupils who need extra rehearsal of number bonds. Every worksheet is free to download, and you can open any of them in Chalkie to edit questions, tweak difficulty or regenerate a version matched to your class.
