Lines, angles, and rays! Oh My!

We have been studying geometry in Math this week. I have been up to my eyeballs in attributes of circles, lines, line segments, rays, angles, parallel, perpendicular, you-name-it! I've really enjoyed teaching these ideas and my students have had fun learning, mainly because I have taught tons of songs and played lots of Simon Says (as an assessment tool of course!)

Here are a few songs:

This song, to the tune of (Miss Suzy Had a Steamboat) Slightly inappropriate lyrics but you know the tune, teaches about lines and angles.

A line has two arrows (arms out pointing in both directions)
It goes on and on.
A segment has two endpoints (arms out with balled fists)
A ray has only one. (one balled fist, one finger pointing)
When I make a muscle (duh, make a muscle!)
It's a right angle, too.
Look at my square corner, (point to elbow)
You can make it too!

Right! Acute! Obtuse! (Make each angle with arms)

The next song, to the tune of "Where is Thumbkin" teaches the three pairs of lines:

Perpendicular, perpendicular.
Parallel, parallel.
Intersecting line, intersecting line.
All is well, all is well.

I have my students make each pair of lines with their arms as we sing.

After we learned about kinds of lines, angles, and pairs of lines, we played Simon Says! I've learned that 3rd graders are really BAD at this game! They can make all the hand motions all right but they can never remember to stay put if I don't say Simon Says first! I can get the whole class out in one full swoop!

Other activities I wanted to do, but didn't have time to do are listed below:

1. Musical Angles: Give each student a piece of string. With music playing, students move to the music. Stop the music and call out a different angle each time. Students must pair up to make the angle. If they don't have a partner or they make the wrong angle, they are out.

2. Line Collage: Give your students pipe cleaners, toothpicks, popsicle sticks, construction paper, crayons, markers, or just whatever else you choose to make a collage with parallel, perpendicular, and intersecting lines and let em' at it!

3. Angle "Tic Tac Toe": Click on this link for an assessment of right, obtuse, and acute angles.

4. United Streaming: If you have access to this site, you can have students watch the Math's Mansion: Learn Your Lines segment or Videomath: Lines.

What other activities, songs, or chants do you use to teach this concept in your classrooms?
