Especially as a IS Teacher I would like to have posters around the room to help remind the students of material covered. I would also allow the students to use the posters during a test- the posters might not be the main idea of the test but it could be a part of it so it can be used as an aid.
This "mini word wall" sample has four different words relating to geometry and spatial reasoning. Each word and graphic is colorful, handmade, and eye-catching. The words are reflection, rotation, translation, and dilation. Make this page into a poster, hang on your word wall, turn into flash cards, or print for each individual student. Enjoy!
