11. LEARNING TARGET 3.3 Proportions – How can you use proportions to tell when things are fair? Today I can compare unit rates to determine when things are fair or equivalent by answering at least two out of three exercises from the book correctly. TCAP STANDARDS 1.4a Use the relationships among fractions, decimals, and percents, including the concepts of ratio and proportion, in problem-solving situations. 6.1a Use concrete materials or pictures to explain how ratios, proportion, and percents can be used to solve real-world problems.
