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.
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.
After this video lesson from Classroom Connection, students will know the difference between a trapezoid and a parallelogram, and be able to answer the question, “Are you a square?”
Students will use an iPad app, Amaziograph, to create digital media artwork. They will use angles and lines on a rotation grid to create their art. This lesson was a collaboration between a math teacher and an arts integration specialist.
In this lesson, students observe symmetry, geometric shapes, and angles in two Early American dances, and then choreograph their own dance with symmetrical figures. Three options are provided in this lesson depending on the time in class. In all three options, students will observe symmetry in dance.
Students will compose music grooves using math concepts such as shapes, angles, and patterns. Start working with one of the "specials" pizza presets and add/remove "toppings" to adjust the groove, or click on the "Shapes" tab and drag various shapes onto the big circle to play and explore math-inspired grooves. The shapes include triangle, quadrilateral, pentagon, hexagon, and octagon. They can download their compositions or share a link to the composition.
This classroom resource provides a slideshow that introduces the types of lines. There is a karaoke song with printable lyrics that will help students learn and review the types of lines. After utilizing this resource, the students can complete the short quiz to assess their understanding.
In this interactive activity, students will be led through steps to identify angles as obtuse, acute, right, or straight. There are teaching activities as well as practice activities available. A handout that reviews the types of angles taught during the interactive is available to be printed. After utilizing this resource, the students can complete the short quiz to assess their understanding.
