Using two identical sets of Christmas vocabulary flash cards, set up a game of pairs for the class. Shuffle the cards and lay them out facedown. In turn, each student turns over two cards and identifies the vocabulary item. If their cards match, they keep the pair; if not, they turn them back over. The winner is the person with the most pairs at the end.
Each child is given a bingo sheet made up of nine squares, each containing a vocabulary item. The teacher calls out the vocabulary words in the same way a bingo caller would numbers. To make the game more difficult, the teacher could give clues to answers rather than saying the exact word. An example might be "something green we bring into our homes for decoration at Christmas," with the answer, "Christmas tree."
Although not strictly a game, crosswords are a way of consolidating vocabulary knowledge and can easily be made by teachers. Alternatively, websites such as Anglomaniacy.com or BogglesWorld.com provide printable crosswords.
This game is similar to the children's party classic Pass the Parcel. Ask children to sit in a circle on the floor. Give each child a Christmas-themed flash card and ask them to place it facedown in front of them on the floor. Use a Christmas-themed toy, such as a Santa or a reindeer, to pass around the circle while Christmas-themed music is playing. When the music is paused, the child with the toy must show the class his flash card and use the vocabulary term in a sentence. If there is time, the teacher may then ask other children for other suggestions of a sentence. Allow each child a turn.
