Ratio - Using Scale Factors - Starter

In a set of engaging starter activities designed for Year 6 students during their Spring Term, the focus is on sharpening their mathematical fluency, particularly in the area of ratio and using scale factors. The "Fluent in Four" section provides a variety of problems to solve, including basic arithmetic, Roman numerals, and decimal subtractions. For example, students are tasked with adding numbers such as 7,347 and 856, and performing calculations with Roman numerals like CCXLVI plus 10. They are also challenged to subtract decimals, with questions like 0.14 minus 0.1, ensuring they practice precision in their calculations.

The activities also incorporate real-life scenarios to help students understand the application of ratio and proportion. In one problem, students explore the concept of mixing paint, where Zach combines 18 parts of blue paint with 12 parts of red paint to create violet paint. The question then asks students to determine how many parts of blue paint Zach would use if he takes 4 parts, and then an additional 2 parts, of red paint. This practical approach to learning encourages students to visualise the problem, potentially using a bar model as a helpful tool. The exercises are designed to promote critical thinking and enhance problem-solving skills, setting a strong foundation for more complex mathematical concepts.
