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

In the Year 1 Spring curriculum focusing on addition and subtraction within 20, the teaching plan for Week 3 centres on the technique of 'Add by Making 10'. This method is an essential step towards developing mental arithmetic skills for young learners. The class begins with a recap of previous learning, where children are encouraged to use practical resources such as ten frames, counters, and number lines to visualise and understand number bonds to 10. The teaching input includes showing how to partition numbers using a ten frame to make up 10 and then adding any remaining amount. This visual approach helps children grasp the concept that adding to 10 and then counting on is an efficient strategy for calculation. Differentiated worksheets and teaching slides provide tailored learning materials, while key vocabulary such as 'addition', 'counting on', 'partition', and 'number bond' is reinforced throughout the lesson.

Independent learning activities allow children to apply the 'Add by Making 10' strategy through a series of guided exercises. They practice partitioning numbers on ten frames and number lines, enhancing their understanding of how to reach 10 before adding the rest. The plenary session includes a 'Give me five' reflection activity, prompting students to consider what they've learned and understood, the skills they've used, and any challenges they've encountered. The lesson plan caters to different levels of learning, from 'Working Towards' to 'Expected' and 'Greater Depth', ensuring all students can progress in their understanding of addition. The activities are designed to solidify the concept that the order of numbers does not affect the outcome when adding by making 10, a foundational principle in commutative properties of addition.
