So how does the Common Core actually expect grade 2 students solve 3-digit addition and subtraction? What models are the required to use? How can parents support at home this new way of math?
This is a great handout that explains exactly how parents should be supporting students at home with addition and subtraction models (place value blocks and proof drawings, expanded notation break aparts method, and number lines) It's great to give away at parent teacher conferences and even to put into a students math journal as it shows these ways for addition AND subtraction...six full pages!
You can enlarge it and make it into a poster to use as an anchor chart in your classroom! It makes a great visual of the expectations that you require to see in your assessments too!
