Finally, a fun way to reinforce content area vocabulary! This familiar activity will have students actively thinking about the basic vocabulary of trees. 30 game boards are included to allow for whole class participation. This activity only requires students to recognize the definitions of terms, not generate them, so even if there are a few words included that you have not covered, it is a great opportunity to introduce them. 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. 30 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 one to fit every word called. Options for extending play past the traditional 5 in a row format increase the learning potential. The terms included in this set are: branch, cambium, canopy, chlorophyll, concentric, coniferous, crotch, crown, deciduous, defoliation, evergreen, foliage, germinate, heartwood, knots, leaves, mature tree, native, needles, outer bark, phloem (inner bark), photosynthesis, resin, roots, growth (annual) rings, sapling, seed, trunk, twig and xylem (sapwood).
