I created this unit to align with the Common Core standards. As a first grade teacher, I do not have the resources to teach addition with regrouping within 100 so I made my own! Even though this was made with first grade in mind, this would be great for a review at the beginning of second. The worksheets are great because there is a space beside the two digit numbers for students to draw the base ten representation to aid in solving the equation.
