This geometry math activity reviews basic geometric terms including: perpendicular, parallel, points, ray, line, and line segment.. The activities were designed for an interactive bulletin board, but can also be used as a mini-lesson or math center. There are also programmable cards to add any other terms that you would like to review. This also makes the activity flexible to allow for differentiation. Additionally, there is a worksheet to check individual student understanding. If you like this, check out the other activities I have for math throughout the year (4 per month).
