Fact Triangles
 

Addition/Subtraction Fact Triangles in PDF form

Multiplication/Division Fact Triangles in PDF form


To help students master the facts, you may use Fact Triangles. These triangular cards have three numbers on each corner, an asterisk, or solid dot in the corner, which contains the sum or product, and the operation (addition, subtraction, multiplication, division) in the center.

HOW TO USE FACT TRIANGLES:

The three numbers used in a fact are located on the corners of a fact triangle. The sum of two numbers can be found on the card under a solid dot (   ).The product of two numbers can be found on the card under the asterisk (*). Cover one of the corners of the triangle and ask your child to use the appropriate operation to come up with the number you are concealing. When the operation is subtraction or division, one of the numbers other than the number under the asterisk/dot should be hidden. Addition and multiplication facts may be practiced by covering the sum or the product, but may also be practiced by covering one of the other facts in the number sentence. For example, in the illustration above you would say to your child:
"7 - 3 = ____ or 3 + ____ = 7"

Fact triangles help students learn fact families rather than isolated facts. Children see the relationship between addition/subtraction and multiplication/division facts, providing a more effective devise for mastering the facts than regular flash cards.
