Addition and subtraction within 10 - Addition symbol - Planning

The Year 1 Autumn syllabus introduces the crucial mathematical concepts of addition and subtraction within 10, focusing on the addition symbol in the first week. The lesson plan outlines a structured approach to teaching this concept, starting with a small step starter to recap previous learning. Students are introduced to the addition symbol (+) and the 'equal to' symbol (=), forming their initial number sentences such as 3 + 2 = 5. The language surrounding these sentences is emphasized to help children understand the process of addition, for instance, by using real-world examples like adding apples. The class teaching input includes using concrete counting resources and digit cards to visually demonstrate the concept of addition, while the independent learning segment allows children to write number sentences and explore part-whole models through differentiated worksheets and activities.

Throughout the lesson, key vocabulary such as 'addition', 'plus', 'number sentence', 'symbol', and 'sign' is reinforced, with resources available for further clarification. Partner work encourages discussion and the use of full sentences to explain reasoning, such as "I know that because...". The lesson's plenary involves a 'Give me five' reflection activity where children articulate what they have learned, the skills they used, any challenges faced, and what they will remember from the lesson. The worksheets are tiered according to the students' levels, ranging from 'Working Towards' where children count images to create number sentences, to 'Expected' where they count larger quantities, and up to 'Greater Depth' where they complete more complex addition sentences and calculate missing numbers, fostering a deeper understanding of addition within the context of numbers up to 20.
