Expanded Notation for Third Grade STAAR practice was created by Only Fabb due to a lack of resources for student practice with this type of problems. This download contains 4 pages-just the right amount of practice that your students need to master the skill! There is also an answer key for each worksheet. If you would like to preview the product, there is a free download available in my store. Could be used as homework, classwork, or RTI. Designed for 3rd grade but could be used as review for 4th grade.
