In this Year 1 Working Without Worksheets lesson, children develop their understanding of place value by representing numbers up to 100. Building on their knowledge of numbers within 50, pupils explore patterns within the hundred square, use reasoning skills to fill in missing numbers, and practise estimation on number lines. Through hands-on activities, they learn how tens and ones work together to form two-digit numbers, supporting secure fluency and problem-solving.
