Description

Are you struggling to teach addition strategies? These 3 digit Addition worksheets using the expanded form addition strategy will help your students. They include addition without regrouping and addition with regrouping. Included in this resource are also 2 colorful posters showing the strategy. The guided practice pages are great resources to send home as homework, since the examples at the top show parents how to use the strategy.

Check out the preview to see what is included in this resource.

NOTE: Currently the ONLY digital provided in this resource is using the Easel Activity tool. I have already prepared it by adding answer boxes. All you have to do after you purchase is click on the Easel Activity section under download to get the link to post in Google Classroom. This also works great in a distance learning packet. Other options are that you can post the PDF in your password protected classroom such as Google Classroom. You could also have students annotate on top of the pages using other online annotating tools.
