Scaling - PowerPoint

The Maths Teaching Resources for Year 3 focus on the concept of scaling within the topic of multiplication and division. The interactive PowerPoint presentation encourages students to solve problems involving scaling by completing sentences and answering questions on each slide. For instance, students are presented with scenarios such as "Joe has ____ times as many apples as Bill," and "Lily has ____ times as many cupcakes as Daisy," prompting them to calculate and understand the proportional relationships between quantities. Additionally, the resource includes examples with green and blue cars, asking students to determine how many times greater the quantity of one is compared to the other.

The educational material progresses to more complex tasks where students must identify bar models that correctly represent given statements about the quantities of sweets in jars or cars in a car park. They are also challenged to draw their own bar models to visually depict statements such as the ratio of pink to yellow flowers in a vase. Further exercises involve matching exercises where students pair numbers with those that are two or three times larger or smaller, reinforcing their understanding of scaling. The lesson culminates with problem-solving questions where students must apply their knowledge to real-life scenarios, such as determining how many pencils Ged has if he has five times more than Amy or how many shells Joel has compared to Imran. The resource is designed to clarify common misconceptions and ensure students grasp the concept of scaling through practical and visual learning methods.
