Title: Super Bear: Comparing Mass
URL: https://aptv.pbslearningmedia.org/resource/mgbh-math-md-superbear/super-bear-comparing-mass/
Description:

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.

Title: The Lowdown | Interpret Data With Graphs, Percents, Rate and Ratio: California Agriculture in a State of Drought
URL: https://aptv.pbslearningmedia.org/resource/mkqed.math.rp.parched/interpret-data-with-graphs-percents-rate-and-ratio-california-agriculture-in-a-state-of-drought/
Description:

In this infographic, learn about the impact of drought on agriculture in California. In the accompanying classroom activity, students use the information on one of the infographic graphs to compare the share of production value to the share of water usage for different crops and consider the implications for the choice of crops to grow in times of drought. To get the most from this lesson, students should be comfortable interpreting percentages and double bar graphs and familiar with ratios and rates.
