The Antarctica Project: A Middle School Mathematics Unit
6th - 8th
New ReviewAntarctica is a big place, large enough to provide ample opportunities to learn about math. A two-week unit teaches middle school mathematics concepts using project-based learning. The resource covers functions, geometry (area,...
Points, Lines and Planes
8 mins 4th - 8th CCSS: Adaptable
New ReviewGeometry begins with a point. The video introduces the concepts of points, lines, and planes. Using diagrams, the presenter includes how to name the objects along with how to write the names. Previewing the concept of 3-D space ends the...
Polygon Classification in the Coordinate Plane
6th - 10th CCSS: Designed
New ReviewClassify this resource into the "Use" pile. Scholars use an interactive coordinate plane to plot polygons given coordinates for the vertices. They use properties to classify each polygon and answer a few challenge questions regarding the...
Inductive Reasoning from Patterns: Greeting with Handshakes
6th - 9th
New ReviewGreet this resource like an old friend. An interactive has users investigate the number of handshakes required for a group to greet each member. A set of challenge questions ensures that learners have a solid understanding of the...
Vertical Angles: Yo-Yo Eiffel Tower Trick
7th - 12th CCSS: Designed
New ReviewYo, yo, learn about vertical angles with a yo-yo. Using an interactive, scholars adjust the position of fingers holding a design from a yo-yo. Answering a set of challenge questions based on the interactive helps clarify understanding of...
Linear Pairs: Angles and Lines in a Perspective Drawing
7th - 12th CCSS: Designed
New ReviewGain some perspective on linear pairs. Aspiring mathematicians adjust the vanishing point on a perspective drawing. They see the effect on linear pairs of angles and answer five challenge questions based on their observations.
Linear Equations: Deep Dish Pizza
6th - 9th CCSS: Adaptable
New ReviewExplore the volume of solids with a real-life connection. Learners calculate the volume of a deep-dish slice of pizza to determine its price. They model the slice as a part of a cylinder and create a formula for calculating the cost.
Parallel and Perpendicular Lines
2 mins 8th - 10th CCSS: Adaptable
New ReviewInvestigate parallel and perpendicular lines in the coordinate plane. Watch as the instructor demonstrates graphing the two types of lines. She highlights the patterns of the slope or steepness of the pairs of lines to make the concept...
