AN algorithm for subtraction

CC_BY-NC-SA

A 2nd grade student shared an algorithm for subtraction that was learned at home. This provides a great opportunity to make sense of mathematics! With a focus on place value, the algorithm can be made sense of by our students.  The PDF Pencast simply explains the algorithm...share it in class and use it as a context to make sense of math, develop number sense, focus on place value. NOTE: Adobe Reader DC (or equivalent) is needed to view the "video" aspect of this pencast PDF.

Multiplying Improper Fractions

CC_BY-NC-SA

Instructional videos for multiplying mixed numbers/improper fractions. The intent is NOT to share the most efficient, compact way to multiply. The point is to make sense of multiplication. Part 1 - multiplying two digit whole numbers in context. Part 2 - multipying mixed numbers using the idea from Part 1

Cal Clulus: In Pursuit of Justice!

CC_BY-NC-SA

This project involves a movie that was written by, directed by, and starring Dr. Scott Adamson and Dr. Trey Cox. The focus of the project is making sense out of average rate of change, instantaneous rate of change, and the Mean Value Theorem. Watch this clip first with your class before doing the activity: https://www.youtube.com/watch?v=DBRwU9ubYQo After doing the activity, view the 2nd part of the video at: https://www.youtube.com/watch?v=pqy3VivFs9Y

Rule Time: Salute to Sports!

CC_BY-NC-SA

The purpose of this module is to help students learn important applied mathematical concepts regarding exponential and logistic functions. Students will also learn how to graph and interpret exponential (and logistic, if desired) functions. The unique element of this lesson is the use of video to generate interest in the students and motivate the content through interactive technology, humor, and cooperative learning. Students are encouraged to work together and help each other “make sense” of the activities. You will need these video clips: Part 1 - https://www.youtube.com/watch?v=xUavijWEwaQ Part 2 (after the problem situation is resolved) - https://www.youtube.com/watch?v=GfGj7Ik7Zao

25 billion apps - Dan Meyer Three Act Task

CC_BY-NC-SA

The question is simple: When should you start bombarding the App Store with purchases if you want to win a $10,000 App Store Gift card? The lesson hooks students immediately with the initial video clip of a “live” counter of current downloads showing the number approaching 25,000,000,000. The mathematics deals with modeling a linear relationship between two quantities

Sugar Packets - Dan Meyer Three Act Task

CC_BY-NC-SA

The question is simple: How many sugar packets are in a soda bottle? The lesson hooks students immediately with the initial video clip of a man sitting in a restaurant downing packets of sugar one-after-another! The mathematics involved is proportional reasoning.
