For this project, students create a station.. They are assigned a 3D figure (cylinder, cone, prisms, pyramids, sphere, etc). They must create a station that teaches the parts of the figure and how to find the surface area, lateral area, and volume of the figure. Then students visit each station created and have a quiz on all the stations.

This learning video deals with a question of geometrical probability. A key idea presented is the fact that a linear equation in three dimensions produces a plane. The video focuses on random triangles that are defined by their three respective angles. These angles are chosen randomly subject to a constraint that they must sum to 180 degrees. An example of the types of in-class activities for between segments of the video is: Ask six students for numbers and make those numbers the coordinates x,y of three points. Then have the class try to figure out how to decide if the triangle with those corners is acute or obtuse.

The purpose of this task is primarily assessment-oriented, asking students to demonstrate knowledge of how to determine the congruency of triangles.

"I prefer to think that we arrive at insight by experience..."-Josef Albers Examining art with a mathematical lens can help students articulate how they see and understand spatial and numerical relationships. Use this resoure to explore prints by artist and teacher Josef Albers to help students expand their understanding of geometric concepts such as parallel lines, congruent angles, rectangular prisms and more.The resource includes: Short introduction to Albers and his ideas.Examples of Albers works for examination. Suggested open-ended activity for further exploration Discussion prompts This activity can be structured as introductory exploration or informal formative evaluation. Use student ideas generated as a reference and springboard for more formal instruction and problem-solving.   

Writing and applying the equation of a circle Mathematics Instructional Plans (MIPs) help teachers align instruction with the 2016 Mathematics Standards of Learning (SOL) by providing examples of how the knowledge, skills and processes found in the SOL and curriculum framework can be presented to students in the classroom.

This resource from the Mathematics Assessment Project was found at OER Commons. https://www.oercommons.org/courses/finding-equations-of-parallel-and-perpendicular-lines/view. This lesson unit is intended to help teachers assess how well students are able to understand the relationship between the slopes of parallel and perpendicular lines and, in particular, to help identify students who find it difficult to: find, from their equations, lines that are parallel and perpendicular; and identify and use intercepts.

This resource asks students to determine where a third point could be to create a right triangle, an obtuse triangle, and an acute triangle.

Students will color code each set of triangles to tell which shortcut, if any, can prove the triangles congruent. Shortcuts included are SSS, SAS, ASA, AAS, and HL. Students can complete this digitally or it can be printed out and used as a worksheet.

This resource provides a warm-up, concept development, practice and alternate assessment for Equations of a Circle.

This activity from Illustrative Mathematics has students determine the slope between ordered pairs. The last set of ordered pairs are variables instead of numbers.
