Title: Rise and Shine Math Time: Line It Up! Parallel and Perpendicular Lines
URL: https://aptv.pbslearningmedia.org/resource/line-it-up-parallel-and-perpendicular-lines-video/rise-and-shine-math-time/
Description:

Susanna Post, 2021 Arkansas Teacher of the Year, explains a strategy for remembering the difference between parallel and perpendicular lines. In addition, she demonstrates the meanings of parallel and perpendicular lines by showing real-world examples. A practice page with examples and vocabulary is included as a resource.

Title: Varieties of Quadrilaterals
URL: https://aptv.pbslearningmedia.org/resource/vtl07.math.geometry.pla.lpquadril/varieties-of-quadrilaterals/
Description:

Bianca's friend Kim brings her a device for reaching objects while she's confined to her bed. The device is made up of collapsible parallelograms. The activity uses this episode to launch an investigation of different kinds of quadrilaterals (parallelograms, trapezoids, rectangles, squares, and rhombi) and the relationships among them.

Description:

Students will explore geometry and frogs in the garden by going on a triangle hunt to find, measure and sketch angles, rays, triangles, and parallel and perpendicular lines. Students will create a garden habitat that attracts frogs and toads, hold a triangle-themed party to welcome frogs and toads, and select healthy triangular snacks.

Title: Classify Triangles StudyJam
URL: https://studyjams.scholastic.com/studyjams/jams/math/geometry/classify-triangles.htm
Description:

In this interactive activity, students will be led through steps to identify triangles based on their angles and sides. There are teaching activities as well as practice activities available. A handout that reviews the types of triangles taught during the activity can be printed. There is a karaoke song with printable lyrics that will help students learn and review the types of triangles. After utilizing this resource, the students can complete the short quiz to assess their understanding.
