Addition and subtraction - Subtract one- from two-digit numbers - Starter

In this engaging mathematics session aimed at Year 3 pupils during the Autumn term, the focus is on developing skills in subtraction, particularly subtracting one-digit from two-digit numbers. The lesson starts with a 'Fluent in Four' revision activity that encourages students to practise counting back in tens using a number line to solve calculations. The exercise presents a scenario where students must add nine ones to six tens and then an additional eleven, prompting them to perform the calculation of 38 plus 46 to find the answer.

Further learning activities include completing part-whole models, which help pupils visualise and understand how numbers can be broken down into parts and combined to form a whole. Another exercise involves matching turns to their descriptions, reinforcing the concept of subtraction by finding the difference between numbers. For example, students are tasked with calculating the result of subtracting seventy from five hundred and twenty-five. Additionally, the lesson incorporates a geometry component, where students are asked to name shapes and identify the number of sides they have, such as a hexagon with six sides, a triangle with three, a pentagon with five, a square and a rectangle each with four. These varied activities are designed to strengthen the students' arithmetic and geometric knowledge in a practical and interactive way.
