This task has students determine how much some yogurt costs. There are multiple ways to approach this problem including unit rates, proportions and scale factors. Allow your students to think creatively and critically as they work through this task.

In this video, learn a strategy for solving unit rate problems. In the accompanying classroom activity, students watch the video then use grocery store ads to calculate unit rates and compare prices. They share solution strategies and consider ways that unit rates can facilitate making comparisons. To get the most from the activity, students should be comfortable finding equivalent fractions and have had some exposure to the concepts of ratio and unit rate.

Open Middle tasks provide opportunities for student to approach a mathematical task using different strategies and representations. They can be used as a warm-up/closing activity, as a formative assessment, or to facilitate discourse and discussion and get insite into student thinking and problem solving. These tasks provide a great opportunity for student to engage with the Standards for Mathematical Practice.

Students determine how much of each paint color is necessary to paint the room they are in. Students use their knowledge of ratios and area to accomplish this task.

This lesson is meant to introduce students to the concept of unit rate. It uses a Canva presentation to introduce the concept. For practice, student will calculate the population density of various countries and compare it to the population density of Utah. There is a worksheet to complete during independent practice, an exit ticket, and an extension activity for fast finishers. Image Credits:"Flag Map Of The World" by GDJ is in the public domain through OpenClipArt.org upload agreement"Utah" by Arohletter1 is in the public domain through OpenClipArt.org upload agreementImage Credit: Christian Cragun
