Ratio - Calculating Ratio - Worksheet

The "Calculating Ratio" worksheet is a comprehensive resource designed to help Year 6 students master the concept of ratios through a series of engaging problems. The National Curriculum objective for this lesson is to solve problems involving relative sizes of two quantities, using integer multiplication and division facts. Students are equipped with differentiated sheets and teaching slides to aid their learning. Vocabulary such as 'ratio', 'calculate', 'bar models', and 'represented' is introduced, and children are encouraged to use bar models to visualize and solve ratio problems. They are tasked with worded questions that require them to find parts and wholes within given ratios, with prompts to draw and label bar models to represent their calculations.

As students progress, they move from fluency exercises to reasoning and problem-solving activities, which are designed to deepen their understanding of ratios. They are presented with scenarios such as a farmer planting crops, mixing paint colors, and sorting packets of sweets or marbles, where they must use their knowledge of ratios to determine quantities. Key questions guide them to think critically about how to represent ratios, the value of each part, and the total number of parts. The worksheet provides a structured approach, gradually increasing in complexity, and includes answers for self-assessment. This resource not only helps students practice calculating ratios but also reinforces their skills in multiplication, division, and problem-solving.
