Related Calculations - PowerPoint

This set of educational resources is aimed at Year 3 students learning about multiplication and division. It focuses on the concept of related calculations, where understanding one fact can help solve other problems. For instance, if students know that 3 times 4 equals 12, they can deduce that 3 times 40 will be ten times larger, resulting in 120. Various activities are included to help reinforce this concept, such as completing number sentences using arrays and identifying the correct multiplication or division statements that match given arrays. Additionally, students are encouraged to use their knowledge to solve more complex problems and to identify and correct mistakes in fact families.

The resources also include tasks where students must circle whether statements are true or false, based on their understanding of scaling up or down multiplication and division facts. For example, if 8 times 4 equals 32, then 80 times 4 must equal 320, which is a true statement. Further exercises involve proving or disproving a peer's reasoning, such as determining if a number is ten times bigger than another and what effect this has on the result of a calculation. These engaging activities are designed to build confidence in number manipulation and to deepen students' understanding of the relationship between multiplication and division.
