1. Calculate unit rates of length, area, and other quantities measured in like or different units that include ratios or fractions.

[MA2019] ACC-7 (7) 1 :

1. Calculate unit rates of length, area, and other quantities measured in like or different units that include ratios or fractions. [Grade 7, 1]

In this learning activity, students will learn a strategy for solving unit rate problems from the PBS video. In the accompanying classroom activity, students watch the video and then calculate and compare unit rates. The students will 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.

[MA2019] ACC-7 (7) 1 :

1. Calculate unit rates of length, area, and other quantities measured in like or different units that include ratios or fractions. [Grade 7, 1]

In this learning activity, students will use a learning strategy for solving unit rate problems from the PBS video. In the accompanying classroom activity, students will solve each problem provided in the student assignment. The students will use a ratio to represent each situation and use division to find the unit rate. 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.

17. Convert among different-sized standard measurement units within a given measurement system and use these conversions in solving multi-step, real-world problems.

[MA2019] (6) 2 :

2. Use unit rates to represent and describe ratio relationships.

[MA2019] (6) 3 :

3. Use ratio and rate reasoning to solve mathematical and real-world problems (including but not limited to percent, measurement conversion, and equivalent ratios) using a variety of models, including tables of equivalent ratios, tape diagrams, double number lines, and equations.

Think about the relationships between the weight and size of similar objects. This interactive exercise focuses on using critical thinking skills and estimation skills to predict how many mini and regular gummy bears it takes to have the same mass as a super bear and then requires using data to complete calculations to see if your prediction was accurate.
