Three-Dimensional Printing- In this video from Annenberg Learner’s Learning Math, learn how three-dimensional printers produce physical models from computer design files. Used by automotive manufacturers and consumer products companies, 3D printers rely on design software that breaks down the surfaces of even the most complex polygon shapes into triangles.

<p>This video explores scale models, including 1:12 dollhouse models, 1:24 railroad models, and 1:192 architectural models. It explains what the different ratios represent and asks students to consider how they can use measurement and proportional reasoning to create their own scale models. The accompanying classroom activity gives students hands-on practice with creating models to scale and with real-world measurement. This resource is part of the <a…

Representing Functions- In this video, watch as the National Museum of Mathematics’ “organ function grinder” represents a function (2x2 – 3) with verbal descriptions, algebraically, and musically. In the accompanying classroom activity, students watch the video and then generate another function (ax2 + b).

Comparing Algorithms: Guess My Rule- In this interactive from Annenberg Learner’s Learning Math, play “Guess My Rule,” a game that lets you use a function machine to guess three mystery algorithms. You will test inputs and outputs against the inputs and outputs of the mystery algorithm. When you think your algorithm matches the mystery algorithm, reveal the algorithm to see if you’re right. Your goal is to guess the rule using as few output requests as possible.

Modeling Fraction Division, Equal Groups, Number of Groups Unknown - In this animated video, a visual model is shown for solving a word problem involving the division of fractions. The problem asks students to determine how many equal-sized narwhals are within a whole pod. Then, students work through a similar but more difficult problem with the help of bar models and other visual representations. #Math #MathGames #MiddleSchool #CommonCore

Piano Tuning and Balancing Equations- In this video from Annenberg Learner’s Learning Math, innovator David Stanwood explains how he used the concept of balancing either side of an equation to improve the way concert pianos are tuned. In the accompanying classroom activity, students become familiar with the piano action mechanism on which Stanwood’s equation is based. They watch and discuss the video and then solve algebraic equations using Stanwood’s method.

Compound Probability- In this video, learn how to find the probability of drawing a heart or queen from a standard playing card deck. In the accompanying classroom activity, students solve problems involving the probability of picking particular cards at random. Next, they consider the probability of randomly drawing a heart or queen and compare their solution strategies with the approach demonstrated in the video.
