#Christmasinjulyl: Addition Task Cards for sums to 20 are the perfect way to review and learn the math facts. These cards are for those harder single addition facts such as 9+8. These cards are just for adding 6, 7, 8, and 9. I used these cards throughout the year in first grade and will be using them again this year as I loop to second grade. They will be the perfect resource for back to school review and assessment in 2nd grade.
