It's a very simple way to get the students to practice reading CCVC/CVCC words in a fun competitive way. Pair up the students and the must read one word in turn. One student will be the top colour and the second the bottom colour. Once the student has read a word have him/her roll the dice and write down the score in the bottom half. When they're finished reading every word that is in their colour whoever has the most points wins the game.
