Addition and subtraction within 10 - Fact families 8 facts - Presentation

In a comprehensive mathematics presentation, students are invited to delve into the concept of fact families with a focus on understanding the interconnection between addition and subtraction within the number range of 10. The lesson encourages children to recall and use mathematical vocabulary related to these operations. The core of the lesson revolves around creating eight related calculations, known as fact families, which demonstrate how numbers can be combined and broken apart through addition and subtraction. This concept is visually reinforced through images that prompt students to generate various number sentences.

Further activities guide students to apply their understanding of fact families in practical scenarios. For example, they are asked to write eight number sentences that reflect a given situation, such as a set of hats on a shelf with different colours, or a group of umbrellas, some blue and some red. These exercises not only reinforce the relationship between addition and subtraction but also encourage logical reasoning and the ability to represent mathematical concepts visually. The presentation culminates with reasoning challenges that ask students to identify and correct mistakes in given calculations, as well as to explore the different ways to partition a set of counters, deepening their comprehension of fact families and the equivalence in addition and subtraction.
