These addition and subtraction triangle flash cards include all fact families 1-18. Instead of learning addition and subtraction facts in isolation, the cards allow them to visualize 4 fact families and two operations as a whole unit.
Included in this packet you’ll find:
- a recording sheet (great for accountability at centers...you could also program the cards with target families and use as homework or classwork)
-2 larger recording sheets for small group work - I recommend laminating or inserting them into page protectors and using dry erase markers
-1 page of blank pumpkin pie cards designed for you to manually record target facts as needed for individual students
-17 printable pages (6 cards each) of full-colored triangular fact family cards (0-18 facts)
Allow the children to use plastic utensils as manipulatives to model the equations
Print 2 sets and use them as a matching / memory game.
Cut the corner off an envelope and use it to cover one of the numbers on the card. Have the students identify the missing number.
