I created this true or false number sentence color sorting activity for students to practice their basic addition and subtraction facts. If the number sentence is TRUE, they color it one color, and if the number sentence is FALSE, they color it another color. There are 3 worksheets included in this pack--one addition, one subtraction, and one mixed. Great practice for math centers, seatwork, morning work or even homework! Also, please to go my store and check out my Fall, Summer, Spring, Halloween and Valentine's Day True or False Color Sorting Worksheet leveled packs, as well as my Winter, Spring, Halloween, Fall, St. Patty's Day and Summer True or False Number Sentence Cut and Paste Sorts! Thanks and Enjoy!
