This resource is from Tools4NCTeachers. This is a set of nine (9) tasks, which may be used for instruction or assessment. Each attachment contains a separate task, rubric, and student recording sheet. The word problems in these tasks involve 'adding to' or 'taking from' a quantity. In these specific problems, the change is unknown. For example:There were 17 ducks in the pond. Some flew away, and now there are 8 ducks in the pond. How many ducks flew away?Remix this resource to include student work samples or addtional tasks.

In this lesson, students use their understanding of word problems to sort problems based on type. The focus for students in this lesson shifts from solving word problems to analyzing word problem structures in order to group like problems. The purpose is to help students understand and visualize problems so they will know how to write equations that match and know what operation is needed to solve. This lesson focuses on sorting addition and subtraction word problems with a specific focus on Take Apart and Put Together types. The lesson, however, can be adjusted to use with any problem types you notice students need more experience with. You could also adjust the number size in the problems to use this lesson at different times in the year.
