New ReviewBuild foundational knowledge of volume by building boxes. Given dimensions for a piece of grid paper, young mathematicians determine the number of possible open-top boxes it will make. As part of this task, they also find the box with...

New ReviewThis resource will blow your mind! Young mathematicians estimate the rate of volcanic lava flow by watching a video. They apply the rate formula to determine how long it would take the lava to reach a city. Let's hope everyone gets out...

New ReviewTwo to the fourth equals four squared. Scholars work through a word problem to find the equivalent expressions in a bake sale. Then they create another exponential expression to represent the same number.

New ReviewWhat comes first, the exponents or the multiplication? Follow the order of operations and you will never make a mistake! Young scholars learn the order of operations and then watch as the instructor evaluates a five-step problem. The...

New ReviewSimplifying expressions in a nice, orderly fashion is ideal. Young scholars learn to simplify expressions of the form a + b(c - d(e^2 + f). The exercise obviously requires meticulous use of the order of operations.

New ReviewBreaking down the order of operations doesn't get any easier than this! Young mathematicians watch a YouTube video that explains how to evaluate a numerical expression using the order of operations. The expression involves integers and...

New ReviewAlways operate under the assumption that the order of operations applies. An informative video shows viewers how to use the order of operations. It goes through four examples and explains how to evaluate each expression.

New ReviewCustomers often want ribbon around fancy cakes, but how does a baker know how much ribbon to buy? Scholars view a cake with multiple layers in different geometric shapes. They must figure the perimeter and circumference and add them...

New ReviewCan the distributive property help solve complex multiplication when you can't find a calculator? Yes, as a matter of fact, it can! Using addition, subtraction, and area models, the speaker explains how to simplify these problems and...

New ReviewWho needs parentheses, anyway? Understanding how to apply the distributive property—and how to get rid of parentheses—helps scholars conceptually understand why it is necessary. Guided practice problems help build confidence to create...

New ReviewHow quickly does light travel long distances? A short video simulates light going from the earth to the moon at two different paces. Scholars relate the distance to the rate to understand which simulation is correct.

New ReviewWhat is the world record for a dog popping 100 balloons? Viewers observe as a dog pops 25 balloons and must figure out how long it should take for the canine to pop the other 75. They discover the previous record and predict if this dog...

New ReviewGraduation ceremonies are huge milestones, but sometimes waiting for a name to be called gets a bit boring. Scholars find the pace the announcer calls names to determine how long until a specific name is called. Calculations work in...

New ReviewWhat energy drinks have the highest concentration of caffeine? Pupils compare five energy drinks with different amounts of caffeine and different volumes. They must solve the ratios to understand the differences. An extension compares...

New ReviewDon't let your eyes play tricks on you ... use scale to keep your eyes in check! Young scholars observe images without scale and try to identify the structure. Then, they look at the same image with a scale bar and assess whether their...

New ReviewChart your way to an understanding of nanoscale. Using a Google map, learners estimate a radius around their location of 1,000 and 1,000,000 meters. Predicting what 1,000,000,000 meters would look like takes them off the charts!...

New ReviewThe incredibly shrinking meter—decimeters to centimeters, to millimeters, and now to nanometers! Learners may have a difficult time visualizing particles on a nanoscale. Help them see a little clearer using a well-designed lesson that...

New ReviewCan you visualize one billionth of a meter? It's not easy to understand the scale of a nanometer. Learners use a hands-on lesson to develop an understanding of the size of a nanometer in comparison to common objects. They walk away with...

New ReviewCan you solve it?! A New York City art challenge involves making sculptures from cans. The task is to determine the number of cans used in the engineering award-winning sculpture. Scholars consider the patterns in the different layers to...

New ReviewBear with your classes as they explore unit rate and proportions using gummies! Gummy bears come in many different sizes, including a 2,250-gram super bear! The task asks learners to determine how many regular bears and how many mini...

New ReviewPackage design is an economic necessity. Young scholars assume the role in an interesting inquiry-based lesson. Given 24 cubic shaped candies to package, they must determine the arrangement that uses the least amount of cardboard to...

New ReviewMath is like another language with a vocabulary all its own. Translating verbal statements to mathematic symbols is a challenging task for learners. The video instruction provides several examples viewers watch—and rewatch—to improve...

New ReviewTo add or subtract ... how do you make the decision? The video instructor explains the process of writing a numerical expression from a verbal expression. While writing the expressions, he provides explanations for his decisions.

New ReviewExpress yourself! Using a table method, the lesson presentation explains how to convert a verbal expression into an algebraic expression. The examples include problems with a variety of operations.
