How did the chicken travel down the road? Given a picture of a chicken truck, class members brainstorm what information they need to determine the total number of chickens on the truck. Pupils research for the information and devise a...

Time for your classes to show off what they've learned! The 11th installment in the series of 24 uses concepts learned in the previous 10 lessons to create the perfect shampoo formula. Their formulas consider both sustainability and...

One step at a time, pupils practice their measurement techniques as they analyze their stride length. They design their own procedures for measuring and relate their stride measurements to the distance traveled by making calculations.

It is close enough for all practical purposes. Pupils see two methods to convert degrees Celsius to degrees Fahrenheit, one with exact numbers and another using estimation. Learners review both methods and determine when the estimation...

A trip around the world sounds nice, but for now we'll just have to make do with Google Earth. Pupils use pictures of landmarks to apply geometry concepts. They determine whether each building has bilateral or rotational symmetry, search...

Geometry is all around us—if we're only willing to look. The final three activities of the Fun with Solids unit continue work on surface area and volume. For lesson three, scholars investigate the formulas for spheres and solve a problem...

Doesn't trying two substitutions prove it is equal? Individuals analyze a given polynomial division problem to determine whether the answer is correct. Classmates continue to determine what values to use that show the answer and the...

Apply the video to learn about applications of function notation. Viewers of an educational video see an example of how to use formulas written in function notation in real-life situations and how to interpret function notation. They...

What to do with more than one variable? Part of a larger series, the video shows how to solve a formula for another variable. Pupils solve equations with more than one variable for a given variable of interest. Problems include linear,...

Jane has 20 bananas and gives 16 away; how many are left? Microsoft Excel can help with that! A video provides a brief overview of the software program. Viewers learn how to use planning, basic math, and knowledge to solve real-life...

Are there some rectangles that are more square than others? A thought-provoking task asks individuals to create a formula that objectifies the square-ness of a set of rectangles. They then use their formulas to rank a set of rectangles.

Build spreadsheet skills while investigating decimal multiplication. An open-ended task asks learners to edit a spreadsheet to create a multiplication table for decimals. Provided with a specific interval, pupils create formulas that...

Learners create patterns in a table to mimic the function of an electronic spreadsheet. The result is a table that creates an addition table for decimals in intervals of one-tenth. While creating the pattern, pupils must thoroughly...

One step at a time! A seemingly linear relationship becomes an entirely new type of function. Young scholars build their understanding of step functions by completing a three-stage activity that incorporates multiple representations of...

Formulas don't appear from thin air! Learn how to derive the quadratic formula by completing the square. As the video instructor demonstrates each step of the derivation, the quadratic formula begins to emerge until it is complete in the...

Learn the stories a formula holds. An interesting lesson takes a unique approach to teach how to use formulas. Beginning with a formula, learners predict what the variables stand for and then use the formula to make calculations and tell...

Math has a language all its own. A well-designed video explains the mathematical language related to equations and formulas. The instructor uses common language to describe the symbols and operations people expect to see when working...

There's a formula for that. An educational video shows viewers how to apply geometry formulas to solve problems. It covers the formulas for the circumference of a circle, volume of a cone, and the Pythagorean Theorem.

Drawing the perfect circle is harder than one would think! What makes a circle a circle and how can you define that with a formula? Young mathematicians devise their own methods of analyzing the imperfections of circle drawings. Using...

Recycle, reuse, and rearrange! Young scholars learn to rearrange formulas to highlight a variable of interest. They then use their new formulas to make calculations.

Fall for a series. Learners determine how to find out how far a skydiver falls in the first 20 seconds. The Algebra II lesson introduces the idea of adding up the terms of an arithmetic sequence. Pupils learn how to use Sigma notation to...
