Trend T1670 Three-Corner Addition and Subtraction Flash Cards - 48/Pack

Trend TEPT1670 Details

Help your students learn basic math facts with Trend T1670 three-corner addition and subtraction flash cards! These innovative triangular cards take a unique approach to displaying numerical information that helps to establish and reinforce the relationship between addition and subtraction. Every card features a number in each corner, one of which is a different color than the other two. To use the cards, cover one number with your hand and look at the other two. If the numbers are the same color, add them together, and if they are different colors, subtract one from the other. To check your answer, lift your hand: the number underneath is the solution to the equation!

Each card features a family of facts. For instance, if a card has numbers 6, 7, and 1, it can be used to review the equations 6+1=7, 7-6= 1, and 7-1=6. Thus, the cards help to show students how closely addition and subtraction are related by revealing the relationship between the three featured numbers.

The double-sided cards cover addition and subtraction math facts for numbers 1 through 12. Kids love these cards because the self-checking feature makes them perfect for solo practice (as well as supervised review!), while parents and teachers love them because their unique presentation of mathematical information makes equations easy to understand. Their durable construction ensures that these cards will hold up even though kids will want to use them over and over again! This product is perfect for teachers of elementary-aged children 6 and up and is sure to quickly become a classroom favorite.
