![]() Activity 13 Similar Solids takes this one step further by extending the investigation to look at the relationship between the volumes of similar solids. Activity 11 formalises the learning from the previous example, includes circles and real contexts. The language used for negative scale factors may need some explaining.Īctivity 7 investigates further the concepts of congruence and similarity in relation to area in similar figures. Both sets could be used as part of the same lesson to make the connection clear to learners. Activity 12 explores negative scale factors. ![]() You cant tell them apart from each other. Similar triangles presents students with a number of triangles and requires them to be grouped into sets of similar ones.Īctivity 5 explores fractional scale factors. In math, when two geometric shapes are congruent, they are like identical twins. Students are required to investigate what happens to the areas of these shapes. Students are presented with a trapezium that has been enlarged by different scale factors. Areas of similar shapes is a little more advanced but ideal for extension work. Shapes that can grow requires students to find scale factors by calculating how many times one shape fits into another. This resource has a number of activities appropriate to this topic. Quality Assured Category: Mathematics Publisher: SMILE Classroom experience suggests that pupils’ understanding of enlargements and similarity can be developed through a range of practical and mental activities. Mental methods that pupils develop to solve ratio and proportion problems can be extended to their work in geometry. Making this link plays an important part in helping pupils to see the ‘big picture’. Enlargements and similarity are applications of ratio and proportion. This booklet includes enlargement and similarity. If your teacher asks you to pause the video and look at the worksheet you. It includes some of the aspects of geometry that have been identified as having implications in terms of understanding of geometry. In this lesson, we will learn about the conditions for congruent shapes and. ![]() Originally written for key stage 3 the resources include some interesting activities and probing questions that can be used to check and challenge existing knowledge. This booklet from National Strategies describes teaching approaches that can be used to develop mental mathematics abilities beyond level five.
