This worksheet can be used for students to create fact families using addition and subtraction. The students write the three fact family number in each corner of the triangle (ex. 3,4, and 7). Next to the triangle are blank formulas where students can fill in the equations for the fact family (ex. 3+4=7, 4+3=7, 7-3=4, 7-4=3). Great student resource for a math folder or portfolio. A square was created in the upper right corner of the page where you can write down which number family you are working on, such as 3s or 4s. There are ten triangles so you can add the numbers 0-9 to the number you are working on.
