This is a set of "math triangle" flash cards, with sums up to 20, tens facts up to 100, and 'quarters' up to 100. There are 150 flash cards, plus 3 blank cards to create any other math triangles you may need! Print on cardstock, cut, and laminate for lasting flash cards! These cards are versitile and can be used in many activities and games to practice addition and subtraction. (Ex: Student holds up a card covering one number; his or her partner figures out the missing part or whole number).

Double Digit Addition: Tens and Ones Work Mat Ten frames in the ones place helps students organize the ones as they add two-digit numbers. They can see clearly if they have made a new ten, and how many are left over. Enjoy! :)
