Learn Zillion: Using Unit Rates to Interpret Scale Maps and Scale Models

Discover the scale factor by finding the constant of proportionality. Pupils investigate drawings to determine whether the distances are proportional. The activity defines the scale factor as the constant of proportionality, or unit...

Just how big would it really be? Young mathematicians determine if different toys are proportional and if their scale is accurate. They solve problems relating scale along with volume and surface area using manipulatives. The...

What proportion of learners will benefit from the lessons on proportional reasoning? Class members learn about proportional relationships, from unit rates to writing equations for proportional relationships. Then, they learn to use...

Remodeling projects require more than just a good design — they involve complex fractions, too. To determine whether a tiling project will fit within a given budget pupils calculate the square footage to determine the number of...

See how design and geometry go hand in hand. The activity asks learners to use geometry to design a backyard garden given dimensions of each feature. Scholars work with ratios and scale to develop an accurate scale drawing that includes...

Provide your students with the context and information they'll need to convert gallons to quarts, pint, and cups. In this video, Sal defines gallons, quarts, pints, and cups. Then he uses this information to solve a problem where he must...

Extend an understanding of ratios and proportions to include unit rates. The video lesson compares two prices of different sizes using two methods. The instructor first calculates a unit price for each product and compares the costs. The...

How many yards are in 360 inches? Pupils answer this question with the help of a video lesson. The instructor uses dimensional analysis to complete the conversion. 

Here's a real-world word problem. It involves walking for a certain amount of time. There are some given values to use. So take the given values, set up the ratio and then convert that to a unit rate value. Now use this unit rate to get...

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...
