Addition and subtraction - Fact families - Worksheet

The "Fact Families" worksheet is an educational resource designed to help Year 6 students master addition and subtraction facts fluently up to 20, in line with the National Curriculum objectives. The worksheet provides differentiated activities to accommodate various learning levels, from those working towards the expected standard to those capable of greater depth reasoning. Resources for the lesson include teaching slides and counters, while the worksheets themselves prompt students to explore the interconnected nature of addition and subtraction through the use of part-whole models and bar models. This approach aims to deepen the children's understanding of the relationship between the parts (addends or subtrahends) and the whole (sum or difference).

Vocabulary central to the lesson includes terms such as 'addition', 'subtraction', 'part-whole model', 'facts', and 'equals sign'. Students are encouraged to identify all related facts within a fact family, understanding the purpose of the equals sign, and the addition and subtraction signs. Key questions posed in the lesson guide students to think critically about the parts and the whole within mathematical models and to determine how many different number sentences can be formed from a single fact family. The activities range from filling in missing numbers on worksheets to cutting out pictorial representations and writing all associated facts in their books, thus catering to different learning styles and reinforcing the concept of fact families through varied methods.
