# Similar Shapes Calculations

Students learn about the relationship between the length, area and volume scale factors of similar shapes.  As learning progresses they apply these relationships to calculate missing dimensions for a range of 2D and 3D shapes.
##### Differentiated Learning Objectives
• All students should be able to use the length and volume scale factors in similar 3D shapes.
• Most students should be able to use the length, area and volume scale factors in any similar 2D or 3D shape.
• Some students should be able to use the length, area and volume scale factors in any similar 2D or 3D shape with algebraic dimensions.

#### How to Draw a Venn Diagram to Calculate Probabilities

There are three common ways to organise data that fall into multiple sets: two-way tables, frequency diagrams and Venn diagrams.  Having blogged about frequency diagrams before I thought I would write about how to draw a Venn Diagram to calculate probabilities. Recapping Two-Way Tables This activity works well to review two-way tables from the previous […]
