Addition and subtraction within 20 - Add ones using number bonds 2 - Starter

In an engaging mathematics session for Year 1, students delve into the world of addition and subtraction within the number range of 20. The lesson is structured to enhance fluency in basic arithmetic through a series of exercises. To begin, children use counters as a tactile aid to calculate sums, which helps them to visualise and better understand the concept of adding ones. The activity is designed to be interactive and hands-on, allowing the young learners to actively participate in their learning process. They are encouraged to complete addition problems by utilising number bonds, a fundamental skill in early maths education.

The lesson continues with pattern recognition exercises where students are prompted to continue a given numerical sequence, further reinforcing their understanding of number relationships. Additionally, they tackle equations such as "16 + 3" and "13 + 6", practising the commutative property of addition by also solving "3 + 16" and "6 + 13". This approach solidifies their comprehension that the order of numbers in addition does not affect the result. To develop their comparison skills, learners are asked to order numbers from greatest to least. Subtraction is also incorporated into the lesson, with problems like "Twelve - 6" and "Double 7 - 6", where they apply their knowledge of number doubling and subtraction to find the answers. The session is a blend of reinforcing known concepts and introducing new ones, tailored to the developmental stage of Year 1 students.
