This product was created at the urging of many teachers and parents alike. Our parents were desperate for something to put their hands on so they could provide help at home with homework and test preparation.
This will be the most helpful piece of material you can give your parents as you start teaching adding and subtraction with the common core.
As you teach the strategy of using place value blocks, parents want to help out with homework and test preparation, but since there are very few resources and they were not taught this way, they will be seeking help from you. Send these parent guides home as you teach these skills. These guides have step-by-step explanations with picture models of the very skill you are teaching in your classroom.
In addition, there are accompanying sheets to be used as homework or classwork practice that are aligned with each parent guide. If you are new to teaching using place value blocks, then these guides will be your salvation as well.
