In this video segment from Cyberchase, Harry plays a game of chess with a young friend and suggests a wager on the game. Harry?s friend uses a story to explain how putting a penny on the first square and then doubling the amount on each square of the chessboard can generate a tremendous amount of money over time. Teaching tips are also provided that discuss frame, focus and follow-up suggestions for using this video in a math lesson.

In this video segment from Cyberchase, the CyberSquad is trying to escape from a desert island by crossing a large body of water. They find a special lily pad that was left for them by the Red Warrior. When the lily pad is put in water it doubles and the number of lily pads keeps on doubling. The CyberSquad tries to use this doubling effect to help them create a lily pad bridge to cross the water and escape. Teaching tips are also provided that discuss frame, focus and follow-up suggestions for using this video in a math lesson.

Students learn how different characteristics of shapes—side lengths, perimeter and area—change when the shapes are scaled, either enlarged or reduced. Student pairs conduct a “scaling investigation” to measure and calculate shape dimensions (rectangle, quarter circle, triangle; lengths, perimeters, areas) from a bedroom floorplan provided at three scales. They analyze their data to notice the mathematical relationships that hold true during the scaling process. They see how this can be useful in real-world situations like when engineers design wearable or implantable biosensors. This prepares students for the associated activity in which they use this knowledge to help them reduce or enlarge their drawings as part of the process of designing their own wearables products. Pre/post-activity quizzes, a worksheet and wrap-up concepts handout are provided.

This set of resources contains sample Number Talk lessons. Lesson 1 builds addition fluency using double ten-frames by making ten and adding more. Lesson 2 builds addition fluency with equations by making ten and adding more. Lesson 3 uses dot cards as representations of numbers to build math language as well as fluency with decomposing numbers within 10.
