Addition and Subtraction Cards Have Never Been So Fun!
Three-Corner Flash Cards are teacher created, child tested cards that encourage students to have fun while learning to add and subtract. There are 46 two-sided cards with all facts 0-12 for addition and subtraction properties. The cards will help students understand number values, recognize number patterns, develop problem-solving skills, and see how addition and subtraction are related.
To start, cover a corner with your hand. The numbers are color coded on each card - simply add when the colors are the same and subtract when the colors are different! The answer will be under your hand. Each card has three problems. Included with the cards are detailed instructions along with fun activities to do with the cards.
