What does it mean for something to grow exponentially, and how does that compare to linear growth? This activity tries to help learners gain an understanding of these concepts while modeling real-world problems. Linear and exponential...

Use of the resource = Opportunities for increased learning. Learners must use equations and inequalities to solve real world and geometric problems. 

Context is the key to understanding slope. A real-world application of slope uses a weight loss scenario with a constant rate of change to introduce the concept of slope of a line, before it makes a connection to the ordered pairs and...

Applying unit conversions to word problems and scenarios is the name of the game in this approachable and yet dense presentation. A wide range of rate, ratio, and proportion problems are covered in a step-by-step manner, with particular...

In a STEM-focused curriculum, units and conversions are front and center in the accuracy and reasonableness checks. This approachable presentation breaks down both the why and the how of converting units, and then applies the conversion...

How much money is enough money? Future wage earners explore the minimum hourly wage and then use it to calculate monthly and yearly earnings. They use an interactive to consider living costs and determine whether earning a minimum wage...

In this KQED infographic, find out how much an adult in different-sized households needs to make to pay for basic monthly living expenses. In the accompanying classroom activity, students solve real-life problems involving rate and ratio...

Good things come in miniature packages. An interesting video from the Math at the Core MS: Ratios playlist introduces the collection of miniatures in the Kentucky Gateway Museum. Scholars use base-10 blocks to create scale models before...

In this activity, 7th graders will use ratios, rates, and unit rates to solve problems.

Upper elementary and middles schoolers discuss and solve real world applications of math. They use formulas for volume and percents to answer real world questions. In the second part of the lesson, groups write and solve word problems....
