Use dance to help learners conceptualize line segments, rays, lines, and planes. They choreograph dances that show dimensional space. Dancers start by pondering space, point, and lines as the teacher draws them in the air. Each movement they make is described in mathematical terminology as it relates to points, segments, rays, planes, and lines. This is a great way to make an abstract concept kinesthetic and tangible for differentiaed learning.
Elementary schoolers explore angles, rays, line segments, and more in a fine geometry lesson. The book, Shape Up! Fun with Triangles and Other Polygons, is used extensively. The plan has lots of hands-on activities and terrific teaching ideas to explore geometric shapes, number of sides, parallel lines, perpendicular lines, and angles. There are also some terrific worksheets and detailed instructions for the activities, which should make implementation of this plan easy.
Here's a great way of teaching how to identify examples of line segments, midpoints, intersections, and parallel and perpendicular lines. Pupils take a walking field trip around the school and locate examples of lines, rays, and line segments, read an informational handout, and complete a worksheet.
Here is a geometry instructional activitywhich invites learners to create models using their knowledge of lines, segments, rays, and angles. This instructional activity reinforces geometric vocabulary and concepts through practical application, it also includes extensions, list of terms, and an assessment.
Rays and angles and Star Wars? It sounds strange, but it's actually a fun game to help fourth graders get good at measuring and identifying angles and rays with a protractor. Each pair of children chooses which Star Wars character they'd like to be, then they each choose a card from their deck, they measure the angle on the card with a protractor and identify the angle. The child with the largest angle wins both cards. The child with all of the cards at the end of the game wins. Tip: This game could take some time to play, set a timer and state that the child with the most cards when the bell rings wins the game.
Sixth graders, after walking around the school yard and parking lot looking for examples of different types of lines, measure the perimeter of the school yard before they draw it using a scale drawing. In the scale drawing, they identify all of the line segments, midpoints, intersections, parallel and perpendicular lines. They complete both guided and student practice.
Sixth graders examine areas around the school to find examples of different types of lines and their relationships. They participate in a guided practice activity in which they add definitions to their ABC of Geometry notebooks. They complete an independent student worksheet demonstrating what they know about lines.
Some of the most important vocabulary in the study of geometry is presented here. In this PowerPoint, learners view the definitions for points, lines, segments, and rays. The definitions and graphics are clear, and kids are also coached on how to "say" the term ("line QS") and how to properly write it using geometric language. A short, but useful presentation.
Fourth graders create a scale model drawing of the playground and identify the line segments, midpoints, intersections, and parallel and perpendicular lines on the model. They take a walk around the school playground, measure the perimeter of the playground, and draw their scale model.
Third graders explore the story telling ability of a line. They use rulers, color, and a variety of lines to show emotion and thought. Paul Klee says, "A line is a dot that went for a walk." Why not extend that idea and discuss rays, points, and line segments while engaging in this creative project? A line design worksheet, a pre-assessment, and two additional handouts are included.
