Adding and Subtracting by Multiples of 10
One way to add and subtract mentally is to understand the role place value plays. Too often, students are taught only one way to add and subtract by using regrouping as the algorithm. While this knowledge is important, having the number sense to add and subtract two and three digit numbers (or more!) helps the student to visualize what he or she is doing when problem solving mathematically.
This set of worksheets gives a brief explanation and example of the thought process behind adding and su

Addition and Subtraction PowerPoint Math Game
Your students will think it’s a game; a chance to “take on the teacher.” You know that by playing this game, your students will review and practice borrowing and carrying skills and practice the steps of the addition and subtraction algorithms.
“Build a House”™ is a fun, fast-paced math game with the same rules as “Hangman,” but instead of your students calling out letters, they call out numbers. Instead of hanging a poor, unfortunate stickperson, incorrect guesses will build you a house.
