Addition and subtraction within 20 - Add by making 10 2 - Starter

In a Year 1 mathematics lesson designed for Spring Term, Week 3, Day 2, children are introduced to the concept of addition and subtraction within 20, with a focus on the strategy of 'Add by making 10'. The lesson begins with a 'Fluent in Four' revision activity where students are encouraged to fill in the missing numbers in a series of arithmetic problems. The exercises are designed to reinforce their understanding of basic addition and subtraction, such as finding the difference between 17 and 8, and identifying the missing addends in equations that sum to 9. The activity also includes a pattern continuation task, which helps to develop their recognition of numerical sequences and relationships.

As part of the learning process, children are presented with a practical problem involving counting objects, specifically doughnuts, to further apply their counting and addition skills. They are asked to determine which box contains 6 doughnuts from a given selection, encouraging them to visually identify quantities and compare numbers. This hands-on approach to learning maths helps to engage young learners and makes abstract concepts more concrete. The combination of written arithmetic problems and visual exercises ensures a well-rounded approach to mastering addition and subtraction within the number range of 20.
