Learners examine objects and find their volumes using geometric formulas in the 21st installment of this 25-part module. Objects take the shape of truncated cones and pyramids, and individuals apply concepts of similar triangles to find...

Temperature rises and land disappears! Through a lab exploration, learners understand the effect of temperature increase on water similar to the effect of global warming on our oceans. As they heat the water in a flask, they measure the...

Turn it up! Sound scientists explore the decibel scale through an interactive that calculates movement up and down the scale. Part of a series of interactives that explore sounds and waves, the resource includes a help feature to support...

Opening up a package of fruit snacks is like a box of chocolates, you never know what you're going to get. When all the mango flavored ones are missing, learners calculate the probability that one bag versus the whole box is missing the...

After watching a video on how to read different types of scales, young mathematicians complete eight problems involving scales. From thermometers to number lines to rulers and clock, class members identify various numbers on scales.

Our final proposal for the cost of the bridge requested is ... In the last segment in a series of 10, pairs work together to develop a proposal for a city bridge design. The class completes a cost comparison between concrete and steel to...

Demonstrate the ratio of surface area to volume in your high school class by using phenolphthalein, gelatin, and an onion. Intrigue the class by leading a discussion on osmosis and diffusion, then making "scientific jello." Participants...

Explore logarithms and logarithmic regression. Young mathematicians first learn about inverse functions and about the logarithm function family. They take their newfound knowledge to use logarithmic functions to model situations and...

Chemistry calculations can look a bit like alphabet soup at times. How do you help pupils make sense of it all? An interactive resource helps scholars sort through the symbols for common quantities such as moles, boiling point, and...

Students identify between appropriate and inappropriate behaviors at work. For this work behaviors lesson, students use a dictionary to define the related terms and visit various links to complete activities that define work place...

The amount of tax and tip on a restaurant bill is a common example used in percent problems. Here, learners only know the total amount paid, and they need to figure the itemized amounts. Solutions using a ratio table, using knowledge of...

Extend young mathematicians' understanding of area with a geometry lesson on trapezoids. Building on their prior knowledge of rectangles and triangles, students learn how to calculate the area of trapezoids and other...

Introduce your classes to a new world of mathematics. Pupils learn to call trigonometric ratios by their given names: sine, cosine, and tangent. They find ratios and use known ratios to discover missing sides of similar...

Travel the world from the comfort of your classroom with a lesson plan that features Google Earth. High schoolers follow a series of steps to locate places all over the earth with sets of coordinates. Additionally, they measure the...

After watching a video on making conversions, young mathematicians solve 16 math problems that involve making conversions of fractions to decimals and percents, decimals to fractions and percents, and percents to fractions and...

Mo' money, mo' problems! But don't worry, here is an assessment that proves to young mathematicians that they can solve actual money problems. The resource includes 11 money problems involving addition, subtraction, multiplication,...

Learners find the midpoint between two numbers, shade fractional amounts of rectangles as well as decimal amounts of rectangles, and explain their mathematical reasoning in words. The assessment is a great way to check for understanding...

After watching a brief video on making metric conversions to standard units, pupils complete tables to describe certain items with the appropriate unit of measurement. Then, they convert liters to millimeters, millimeters to...

Young mathematicians read, interpret, and complete a variety of real-world pictograms. Each question includes a key and information to complete the graphs. 

Reinforce math skills with an eight-page exercise that stretches scholars' computation muscles through 13 order of operation problems. 

Reinforce math skills with an eight-page exercise comprised of 15 problems covering the concept of ratios. 

Practice makes proficient! Here, scholars practice their ratio skills to convert measurements while cooking. Nine problems make up a nine-page document equipped with clear instructions and advice for successful completion while working...

Eleven questions make up an eight-page practice exercise that focuses on how to compute exchange rates. Money used is the American dollar, Euro, and British pound. 

Reinforce the concept of place value with an eight-page practice exercise equipped with 18 problems for scholars to show what they know.
