This lesson is about ratios and proportions using candy boxes as well as a recipe for making candy as situations to be considered. It addresses many Mathematical Reasoning standards and asks students to: Use models to understand fractions and to solve ratio problems; think about a ratio as part/part model and to think about the pattern growing in equal groups or a unit composed of the sum of the parts; find a scale factor and apply it to a ratio. (5th Grade Math) Less

This is a set of four, one-page problems about the size of planets compared to earth. Learners may use ratios to compare planets within our solar system or those outside of our solar system with the earth. Options are presented so that students may learn about the MESSENGER mission to Mercury through a NASA press release or by viewing a NASA eClips video [6 min.]. This activity is part of the Space Math multi-media modules that integrate NASA press releases, NASA archival video, and mathematics problems targeted at specific math standards commonly encountered in middle school.

Students will use ratios to demonstrate the connections between proportional relationships, lines, and linear equations. Students will solve problems using a cooperative, kinesthetic activity in which they will create a ratio table, then graph proportional relationships with their bodies to demonstrate that the ratio (or rate) is the slope that will always pass through the origin.

In Grade 6, students were introduced to ratios and unit rate. They learned to use ratio reasoning to solve problems. Proportional relationships were a major focus in Grade 7. Students learned to compute unit rates that included fractions as well as determine if a relationship is proportional. They represented proportional relationships in graphs, equations, tables, diagrams, and verbal descriptions. In this lesson, students will extend their understanding of proportional relationships to discover that they are one kind of linear function. Aligned with Common Core standard 8.EE.B.5 Less
