Addition and subtraction - Add and subtract 1s - Starter

In an engaging mathematics session aimed at Year 3 pupils, the focus is on strengthening addition and subtraction skills, particularly adding and subtracting ones and tens. The session starts with a 'Fluent in Four' revision exercise that presents a series of calculations to be solved. For example, pupils are tasked with calculating the result of 73 minus a quarter of 16, as well as finding the missing numbers in equations such as subtracting 58 from an unknown number to equal 35. This exercise tests their understanding of basic operations and their ability to manipulate numbers.

The worksheet continues with a variety of arithmetic challenges, including straightforward additions and subtractions like 100 plus 400 and 800 minus 300, as well as problems involving ones and tens, such as combining 7 ones with 4 ones. Pupils are also asked to determine the whole from a given part, such as one third of a number. A practical problem is posed where Leanna collects 12 eggs and breaks a fraction of them; students must calculate how many eggs remain intact. The activity encourages pupils to show their working out, reinforcing the concept of number relationships and providing a clear method to reach the correct answers. The exercises are designed to build confidence in numeracy and develop problem-solving skills in a fun and interactive way.
