How vulnerable are you to COVID-19? High school mathematicians use the Pandemic Vulnerability Index to create models that help them collect and analyze data about the risk factors associated with COVID-19. After investigating four groups...

In this third of a twelve-part series, the focus moves from using matrices to solving systems of equations with substitution and elimination, including more than two dimensions and variables in equations, and analyzing statistical data....

Young scholars measure stuffed animals with various materials such as dog biscuits, paper clips, and yarn. In this measurement lesson, students measure the stuffed animals, and understand the concept of long and short and big and little.

How do you convert from one measurement to another? Pupils use unit rates to convert measurements from one unit to another in the 21st segment in a 29-part series. They convert within the same system to solve length, capacity,...

It's not just a slideshow, it's a lesson on mass. First, learners complete a mental math warm-up, where they determine the number before and after a series of given numbers, then they form groups to weigh packages and compare mass....

How does your class measure up? Young scientists create a scale drawing of the JOIDES Resolution in a collaborative activity. The lesson incorporates mathematical principles with deep-sea exploration to focus on enhancing measurement...

Apply, apply, apply! A measurement activity applies a number of concepts to help learn a new construction. Scholars learn to divide a segment into n equal parts using a method that uses the Side Splitter Theorem and a method...

Conversion immersion — it's measuring mania! A set of four activities teaches scholars to convert between customary and metric units. Resource covers unit conversions in length, temperature, weight/mass, and volume.

In this angle measures worksheet, students solve six word problems where they are given 6 different polygons, some of which are complex, and must determine angle measures in order to arrive at a solution.

Leave no student behind with this differentiated geometry unit on perimeter and area. Over the course of five lessons, young mathematicians explore these foundational concepts through a series of self-selected hands-on activities and...

A set of ten skill-based problems and two word problems make up a metric worksheet in which measuring length and converting units of measurement is the focus.

What kind of tree does a math teacher climb? A geometry! Here is a lesson that includes all the geometry resources you could ever wish for in one comprehensive workbook. Class members demonstrate what they have learned by...

Your learners will be tantalized by this inquiry-based, collaborative activity as they discover how to write an equation that represents the height of an ice cream cone. Given the scenario based on the poem, "Eighteen Flavors," and...

How many seconds are in a minute? Or rather, how many seconds are in eight minutes? This problem is worked out through a series of animated steps and explained by a friendly young lady's voice. Your time travelers will appreciate this...

If Shaquille O'Neal wears a size-20 shoe, how big are his hands? Learners will use the average ratios of foot length to hand span to calculate the hand span of Shaq, but first, they have to collect the data! They will...

Agriculture surrounds us every day; incorporate measuring tools into a study of Oklahoma's agricultural industry! Small groups read an informational text (included) before visiting stations where they investigate prices of various...

Students work in groups to make accurate measurements. In this area and perimeter measurement instructional activity, the student groups determine what they will measure and what tools they will need, then find the accurate measurement...

Should the standard deviation be used for all distributions? Pupils know that the median is a better description of the center for skewed distributions; therefore, they will need a variability measure about the median for those...

When is a foot not a foot? When you use the length of your own foot to measure distances, of course. To underscore the importance of standardized units of measurement, middle schoolers engage in a series of activities that ask them to...

When mathematical errors happen, part of the learning is to figure out how it affects the rest of your calculations. The activity has your mathematicians solving for the area of a circular pipe and taking into consideration any errors...

What is the area? Because there is only one problem here with a detailed explanation below, consider projecting this as an all-class warm up. Learners examine a rectangle split into 12 squares. They know that each unit is three...

Given measurement information on individual squares within a larger shape, scholars determine the total area of that square or rectangle. For one of these three problems they draw the shape knowing its total area and the measurements of...

Connect division with multiplication through the use of models. Groups solve problems involving the division of a whole number by a fraction using models. The groups share their methods along with the corresponding division and...

We use basic units of measurement to break down things and communicate clearly. The first lesson in an 11-part series teaches the proper way to measure various items. It starts simply with measuring the dimensions and areas of geometric...
