Direct Variation ApplicationsLesson Planet
4 mins 8th - 11th CCSS: Adaptable
New ReviewWhat would I weigh there? A video uses the relationship of the weight of an astronaut on Earth and the moon to create a direction variation equation. Using the created equation, pupils find the weight of any astronaut on the moon.
Proportions and Scale: Problem Solving Plan, ProportionsLesson Planet
6th - 8th CCSS: Designed
Slide into a lesson on proportions. A slider interactive lets users adjust three of the four values in a proportion and automatically updates the fourth value. Scholars use the interactive to help answer a set of challenge questions on...
KidVid: Fractions and ScaleLesson Planet
6th - 7th CCSS: Designed
Scale the challenge of learning about ratios and scales. Young mathematicians learn to incorporate fractional measurements when considering scales and scale factors. They use an interactive to investigate the concept and critically...
KidVid: Equivalent RatiosLesson Planet
6th - 7th CCSS: Designed
There's no equivalent to this interactive. To learn about equivalent ratios, scholars first watch a video of a pupil trying to find an equivalent ratio. They consider whether the pupil is correct and explain their reasoning. Then, they...
Math with Jake: Frequencies and PitchLesson Planet
4 mins 6th - 8th CCSS: Designed
Be an octave above the rest. A musician explains how to write music in different time signatures. An interesting resource continues to demonstrate ratios using the pitch of musical notes and hertz. Pupils use a pitch table and determine...
Beating Usain BoltLesson Planet
5 mins 5th - 8th CCSS: Designed
Beating Usain requires a head start. With a race against Usain Bolt as a background, the resource introduces a system of linear equations. A quick activity uses tables to determine whether a head start is enough for the presenter to win...
Human Tree: DilationsLesson Planet
2 mins 6th - 8th CCSS: Designed
Look at dilations exponentially. Using a fractal from a museum exhibit, the installment from the Math at the Core: Ratios series introduces the term dilation. The presenter points out that dilations can make images either smaller or...
Human Tree: RatiosLesson Planet
2 mins 6th - 7th CCSS: Designed
Create a personal tree. By visiting an exhibit at the National Museum of Mathematics, the resource introduces the idea of fractals. The exhibit takes an image of the person and creates a tree by repeating scaled images on the shoulders...
Scale City — Scale Models in the Real WorldLesson Planet
6 mins 6th - 7th CCSS: Designed
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...
Recognize and Represent Proportional Relationships between Quantities: Ratio, Proportion, Cross Multiply, and DivideLesson Planet
3 mins 6th - 7th CCSS: Designed
Review three video clips for one major concept. The resource contains three short clips to introduce the idea of ratios and proportions and how to solve a proportion. After watching the video, partners use their noses to push pom poms...
Why Can't You Divide by Zero?Lesson Planet
5 mins 6th - 12th CCSS: Adaptable
Why doesn't dividing by zero result in infinity? Scholars view an engaging TED-Ed video that describes why division by zero is not allowed. It explains how division is related to the multiplicative inverse, and why 1/0 cannot be equal to...
Building Better Buses: Transportation Design ChallengesLesson Planet
6th - 10th CCSS: Designed
Scholars learn about a series of three challenges when they design a bus system for a small town. They determine the bus routes and then figure out the best type of fuel to use before considering the cost of going electric. Learners...
