Math
Andrea worked with ratios by comparing two quantities and expressing their relationship in the form a:b. She practiced writing ratios from word problems, simplifying them to their lowest terms, and finding equivalent ratios. Andrea also solved proportion equations, discovering how to cross‑multiply to find missing values. Through these tasks she deepened her understanding of ratio language and its role in solving real‑world mathematical problems.
Science
Andrea applied ratio thinking to scientific contexts by examining how quantities relate in mixtures and rates. She calculated the proportion of water to powder needed for a solution, linking the ratio to concentration. Andrea also explored speed as a ratio of distance to time, using simple data to compare different motions. These activities showed her how ratios are essential tools for measuring, predicting, and explaining natural phenomena.
Tips
Tips: 1) Extend ratio work by having Andrea design a scaled model of a garden, using a 1:50 scale to calculate plant spacing. 2) Conduct a kitchen chemistry experiment where she scales a recipe up and down, recording the new ratios of ingredients. 3) Introduce data‑driven projects, such as tracking daily temperatures and expressing the change as a ratio of morning to afternoon values. 4) Use interactive online games that challenge her to match equivalent ratios under time pressure to build fluency.
