These algebraic word problems with give your kids a leg-up on the Common Core Standards for Operations and Algebraic Reasoning (2.OA.A.1).
These problems align with Cognitively Guided Instruction (CGI). They provide teaching slides for how to solve algebraic word problems, as well as differentiated word problems for unknowns in all positions.
This pack includes:
- Teaching slides to teach your students how to solve result unknown, start unknown and change unknown problems (using hundreds boards, number lines and expanded subtraction).
- Three sets of word problems (result unknown, start unknown, and change unknown), each with three different levels (different numbers 2-digit through 3-digit). The wording on each level stays the same so you can review the process as a group while students are able to solve with different numbers according to their proficiency level.
