English term or phrase: fact families
Fact Families (Multiplication and Division):
Success depends on students knowing that once they can recall a particular multiplication fact, they can use that fact to solve related multiplication and division tasks. The set of related facts is called a fact family.
A sample fact family:
7 × 5 = 35; 5 × 7 = 35; 35 ÷ 5 = 7; 35 ÷ 7 = 5; 35 = 7 × 5
Students will already have met fact families for addition and subtraction. They will not necessarily recognise the links between multiplication and division. Students can feel overwhelmed by how many multiplication and division facts there are to learn, unless they see the links between them.
A good command of basic facts is required for carrying out multiplication and division algorithms.

any help greatly appreciated
