This file contains 15 slides with third grade level word problems.
The problems require students to add, subtract, sometimes do both operations, and figure out elapsed time.
The problems have blanks instead of numbers so that you can reuse the same problems many times in order to help kids focus on the operations. Additionally, students can make up their own numbers to use, which requires them to use estimation to make sure they create a problem that is reasonable and possible. Also, teachers can customize the numbers, using the same problems for different groups or using simple numbers if the focus is on the operation and reasoning.
