I made this pack of addition worksheets for students to practice their basic addition facts. The first page is single digit, the second page is single digit plus double digit and the third page is double digit plus double digit. These should be able to be solved mentally. This 3-pack of leveled addition worksheets can be used for practice during warm-up/morning work (this is how I intend to use them--at different points throughout the year--or they could be used for differentiating math groups), a math center, homework, etc. Fun and St. Patty's day - themed! Great for an addition review for any grade! I also have a Fall, Halloween, Thanksgiving, Winter/Snowman, Holiday/Christmas and Spring Addition Pack!--as well as Addition, Subtraction and Division Packs for the various seasons. Enjoy!
