Five a Day - Ratio - Relative sizes and similarity

"Maths Five a Day" is a set of five SATs style questions focused on the topic of ratio, particularly exploring relative sizes and similarity. This educational resource is designed to be used as a starter activity in the classroom, allowing teachers to assess students' knowledge and facilitate retrieval practice. Each question is crafted to mimic the style of questions from past SATs papers, providing students with a familiar format to test their understanding. The answers to each question are conveniently provided on the slide following the question, enabling immediate feedback and discussion.

For example, one of the questions presents a scenario where Marco has stacked 20 boxes to a height of 180cm and then removes 6 boxes from the top. Students are challenged to calculate the new height of the stack. Another question asks students to determine the missing length on a cuboid that has the same volume as a given cube. Additional questions involve estimating the height of adults based on the length of their heads, comparing populations of two capital cities to find out how many times larger one is than the other, and analysing distances between points to correct a misconception. These exercises not only test mathematical concepts but also encourage critical thinking and problem-solving skills.
