Addition and subtraction - Find and make number bonds - Starter

In a Year 2 mathematics lesson focused on addition and subtraction, students are introduced to finding and making number bonds. The lesson starts with a 'Fluent in Four - Revision' exercise where children are encouraged to calculate simple sums, such as 5 + 6, and to count objects to reinforce their understanding of number relationships. They are also asked to use practical tools, like a ruler, to measure lengths, such as determining the length of a chocolate bar in centimetres. The lesson further includes counting different coloured cars—red, yellow, and green—and then combining these counts to find the total number of cars.

As part of the learning process, children are introduced to the concept of part-whole models, which are visual aids that help in understanding how numbers can be split into parts and then recombined to form a whole. For example, they explore how 'one ten add double 2 ones' equates to 14, demonstrating an understanding of place value and the concept of doubling. The exercise also includes finding the related facts for given numbers, enhancing their ability to see the connections between different number combinations. This practical approach to mathematics aims to build a strong foundation in basic arithmetic and number sense for young learners.
