Product Description
This 18-slide PowerPoint presentation introduces the concept of a unit rate. It assumes students have already learned about the concept of a ratio. The material is based on Common Core 6th grade math standard: CCSS.Math.Content.6.RP.A.2. The presentation begins with a problem trying to compare two ratios to determine the best gas mileage. A tape diagram model is used to transform the ratios into unit rates to see how much more helpful they are when making comparisons. Unit rates are calculated using division while the ratios are in fraction form. Language used in describing a unit rate relationship is discussed. Reasons unit rates are useful are also covered. After summarizing, a practice problem is given as well. The presentation should take about 20 to 30 minutes to cover depending on stoppage time for emphasis and student interaction/participation. It's intended for full class use, but can be used individually for remediation or for students who missed the lesson. The PowerPoint can be a great resource to store on teacher websites as well.
