Why is "ambulance" written backwards on emergency vehicles? Young geometers apply principles of symmetry to translate words written backwards. See if your school or district subscribes to Jobland, where you can view a clip that explains...

Learners explore lines of symmetry in geometric shapes. In this geometry lesson, students construct angles using mirrors and rubberbands, then predict the number of images that will appear in the reflection. Learners reproduce lines of...

Students create angles using mirrors. In this angle reflection lesson, students draw angles, then use mirrors to create angles using reflections and measure the new angles.

Students experiment with reflections of two plane mirrors placed at a 90 degree angle to see what will be reflected.

Learners place two plane mirrors at different angles to experiment with reflection. They make kaleidoscopes and periscopes.

In this instructional activity, the students will be experimenting to show how light shines in a straight line. They will also be experimenting to see how light reflects using mirrors. The students will be working in cooperative learning...
