The trunk of the tree or the vertical part of the bookshelves is one word that is formed when the words are put on the branches or shelves. The branches or shelves do not have to be the same length, but they look better if they are. They do not have to have the same number of letters. You can also have, as in the word chains, series of two words with two or three identical letters, at the end of the first word and the beginning of the second. Add one that, in one way or another, does not belong.
Students have to find which one is the distractor and explain why.
On small cards, a little smaller than the squares, write a word or a definition, according to what you have written on the larger cards. If there are fewer words, you can make the same cards for each team and then only the quickest team gets the small card to cover the appropriate square. You can also give a bingo card and a pack of small cards to pairs or teams, and they do the game together. The first to finish is the winner. This is quieter and less frustrating for the students who know the right answer but are not quick enough.
