Addition Strategies

Below are the addition strategies that have been taught and practiced so far this year. Throughout the year, your student will be asked many times to show their thinking when solving an addition problem. These strategies show their understanding of place value and the operation. Please DO NOT teach the traditional method of addition (crossing out and putting the new number above) that we you and I were taught in school. Although this method is more efficient, it does not show understanding of the operation, only the memorization of a process. After students have mastered the strategies below, the traditional method will be taught in fourth grade. Let me know if you have any questions about this! Thanks!!
