I have also added in ‘checkpoints’, which act as diagnostic questions so you can really understand your students misconceptions. Designed to the official Edexcel textbook (by Pearson) it has suggested question practice and page numbers from the book, however this can easily be edited for any textbook or resource bank. You can also add in your favourite starters or questions easily.

#### Ratio and Proportion KS2 Bundle!

This stimulating and comprehensive lesson bundle contains a number of engaging and detailed ‘ratio and proportion’ lessons: Ratio and Proportion: Introduction - Students understand the key terms ratio and proportion, and use these mathematical concepts in order to solve number problems involving relative quantities and unequal sharing. Percentage Problems - Students solve a range of problems involving the calculation of percentages, including for measures and comparisons. Similar Shapes - Students use their understanding of ratio and scale factor to solve a number of varied and real-world similar shapes problems. Combined, the lessons enable children to meet and exceed the following curriculum standards: solve problems involving the relative sizes of 2 quantities where missing values can be found by using integer multiplication and division facts; solve problems involving the calculation of percentages and the use of percentages for comparison; solve problems involving similar shapes where the scale factor is known or can be found 4. solve problems involving unequal sharing and grouping using knowledge of fractions and multiples. Each lesson follows a clear step-by-step learning journey, in which children learn through: -Defining, exemplifying, and understanding the key concepts through clear and simple explanations; -Demonstrating their understanding through well-differentiated (Bronze, Silver, and Gold Challenge) application and challenge activities; -Applying their understanding to real-life problems, for example involving recipes; -Gauging their own understanding through both AfL activities and self-reflection tasks. Included in each lesson is: Whole lesson PowerPoints - clear and precise, colourful and comprehensive; Bronze, Silver, and Gold level award worksheets - carefully differentiated and provided in both Word and PDF; Teacher answer sheets; A detailed teacher lesson plan. Student helpsheets (where appropriate) There are also opportunities for group learning, speaking and listening, peer assessment, and whole class discussion. I originally used these resources with Year 6 (and higher-attaining Year 5) classes, however colleagues have used them for between years 4 and 9 with some minor adaptations. Some of the content really does become quite challenging (especially the Gold sheets) and so these resources could easily be used for KS3 children.
