Have you ever worried about giving a group of students a game to play independently, because you weren't sure that ANY of them knew the skill well enough to check the others' answers? I know I have. That's why I like all my games to be self-checking.*Requires Laminating*
This is a simple-to-play game that will ensure students are practicing correctly. It can be played like regular "Kaboom". I also included the option to play it where players might draw a "Bonus" card (instead of a "Kaboom" card). This way, players don't have to give up their cards, and they have an extra card to count at the end of the game. We have all had that student who might pitch a fit if he or she had the most cards and then had to give them all back when he or she drew a "Kaboom" card.
Outside of cards shows color-coded analog clocks for every 5 minutes. For example, cards show 11:25, 11:30, and 11:35, but not 11:23 or 11:31. Inside of cards show the time as a digital clock would. Cards are sorted by all the o'clocks first, then the 30s, etc. That way, if you want to start off with an easy level for your students, you can easily print just the level of difficulty you need.
