Teacher tips
- Whenever possible, use applets and dynamic geometry software to allow students to experiment with applying transformations to closed figures in the coordinate plane.
- Use tracing paper and cut out figures to allow students to translate, reflect, and rotate figures on graph paper.
- Combine mathematically precise terms with everyday language to help students make sense of transformations. For example, a translation can also be described as a slide, a reflection can be described as a flip, and a rotation can be described as a twist or spin.
