Finally, a fun way to reinforce content area vocabulary for small groups or the whole class! This familiar activity will have students actively thinking about the vocabulary of figures and shapes. Because students only have to recognize the word matching the definition, not generate it, it is ideal for discussing both new and familiar terms. 30 game boards are included to allow for whole class participation. The special calling cards, featuring fold over flaps to hide the answers, also give you the option of using them in centers - small group of students can play independently without a bingo caller. 32 vocabulary words are used on the cards, but each board only has 25; students have to really think about the words and their definitions, because they may not have a word to match every definition called. Options for extending play past the traditional 5 in a row format increase the learning potential. The terms included in this set are: apex, arc, chord, circle, circumference, closed figure, concentric, cone, congruent, cube, cylinder, diameter, ellipse, equiangular, face, hypotenuse, irregular polygon, open figure, parallelogram, perimeter, polygon, polyhedron, prism, radius, rectangle, regular polygon, rhomboid, rhombus, sphere, square, trapezoid and vertex.
