Mr. Weaver's lesson on ratios and proportions focuses on using equations to solve problems by finding missing information in proportional relationships. The lesson covers the constant of proportionality, solving word problems, and directly relating weight and value. Students learn to apply equations like y = kx to real-world situations, ensuring they can find missing data and relate equation parts to scenarios. The lesson concludes with a recap and encourages students to revisit sections if needed.
