LEARNING TARGET 3.3 Proportions – How can you tell when two ratios form a proportion? Today I can determine if two rates are proportional using multiplication, division, or the Cross Products Property by correctly answering at least 2 out of 3 STUDENT questions. 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.
