This is a 'double' bingo game, with 33 filled in cards having a side A and a side B. Side A covers the first part of the 6 weeks - reviewing ratio, proportion, triangle similarity, etc. Side B covers the latter part of the 6 weeks, including special right angles and trig functions. There is also a blank card if you want the students to develop their own cards for the game.
Our students take their cards and try to label each square from looking at the calling sequence page. After 5 - 10 minutes they check their labels against the visual (picture) key and fill in any details you require - the measure of the angles on the special right triangles, etc.
If they mark their cards with highlighters, they can then use their card as a study guide or part of the glossary in their binders.
