This math unit starts with a focus on understanding and manipulating equivalent ratios in practical contexts such as adjusting recipe quantities with whole numbers. It then progresses to solving similar problems involving decimals, emphasizing precision in calculation. As the unit develops, students also learn to handle ratios using fractions, both expanding and shrinking recipes, which enhances their skills in fraction operations and understanding proportions in real-life applications. The unit further advances to solving problems using non-integer multiples for scaling recipes, applying these concepts in more complex scenarios with both decimals and fractions. Students are also introduced to unit rates, where they calculate and compare unit prices in real-world shopping scenarios, utilizing both decimals and fractions. This section of the unit sharpens their practical mathematical skills, especially in financial literacy. Overall, the unit evolves from basic ratio and proportion manipulations to more intricate applications, preparing students to utilize these concepts adeptly in daily situations and complex mathematical contexts.
