These are the high frequency words for Theme 5 in the Houghton Mifflin Series. The document is made so you can put index cards through your printer to print the words onto them. The setup is for 3x5 index cards. Once you have printed these cards, your students can play the game BOOM. All the cards are face downward and the students take turns flipping a card up. They have to read the word in order to keep it. If they read it wrong they put it back in the pile. If a student picks up the BOOM card they have to put all their cards back. Whoever has the most cards in the end wins. *This game usually continues because the cards never run out since a kid is always putting their cards back because of a BOOM card.
