Addition and subtraction - Fact families - Planning

The Year 2 Autumn Addition and Subtraction curriculum is designed to enhance the students' fluency in addition and subtraction facts up to 20, and to understand related facts up to 100. It emphasises the use of concrete objects, pictorial representations, and mental strategies to add and subtract numbers in various combinations, such as a two-digit number with ones or tens, and adding three one-digit numbers. The children also learn the commutative property of addition and the non-commutative nature of subtraction. Through solving problems and recognising the inverse relationship between addition and subtraction, they develop their ability to check calculations and solve missing number problems. Key vocabulary for the unit includes terms such as 'addition', 'subtraction', 'fact families', 'commutative', and 'inverse', among others.

During the lesson on Fact Families, children use resources such as ten frames, Numicon, part whole models, and number sentence cards to explore addition and subtraction bonds to 20. They start by recapping previous learning and then engage in practical activities, like using ten frames to represent and calculate the number of flowers or stars. Partner work encourages them to explore the commutative property of addition and understand that subtraction cannot be done in any order. They rearrange number sentence cards to create different calculations, reinforcing the concept that the equals sign means 'the same as'. By the end of the lesson, students should be able to record the 8 related facts of a fact family and overcome common misconceptions, such as understanding the part-whole relationship and the true meaning of the equals sign. Differentiated worksheets allow for independent practice, and the lesson concludes with a reflective 'Give me five' activity where students consider what they've learned, the skills they've used, and what they found challenging.
