Ratio - Assessment

The assessment on ratio presents various questions designed to test a student's understanding of proportional relationships between different quantities. Students are asked to complete sentences to demonstrate their grasp of ratio in practical situations, such as comparing the number of apples to strawberries or pears. They are also tasked with determining whether Tia's statement about the ratio of sweets she has compared to Malachi is correct, and to explain their reasoning. The assessment includes a variety of questions, ranging from finding equivalent ratios by circling the correct ones to applying knowledge of ratio to solve problems involving shaded parts of bars, the number of boys to girls in a class, and the number of cubes in a tower.

Furthermore, the assessment challenges students with real-life applications of ratio, such as determining the length of a field based on a scale drawing and calculating the enlargement scale factor between two triangles. Students are also required to draw a field to scale on a grid, applying their understanding of measurement and ratio. Additionally, there are questions that involve calculating the difference in the number of red and green grapes based on a given ratio, which tests their ability to work with both parts of the ratio and to perform subtraction to find the required difference. The assessment concludes with an opportunity for students to self-evaluate their confidence level in understanding and applying the concept of ratio.
