Fact Triangles add so much value to understanding addition and subtraction and helping students to become fluent. Students make this book while using counters or block cubes to find ways to make a number. For example: In order to make the number 4 there are three different ways to make it. Students will explore and discover the three ways are:
4+0
3+1
2+2

After discovering the patterns on their own with this book, a classroom chart is made to really see what the patterns are. Then this will lead students to better discovering strategies on their own. This will be a great lead into math talks each day.
