This packet helps students practice subtracting positive and negative numbers (a skill that is essential for algebra and is very often challenging for students!). This worksheet focuses just on numbers between -10 and 10, so students do not have to do long or complicated subtraction problems; they just need to accurately subtract integers. We consider these pages to be drills. We push students to finish them quickly, and make them repeat worksheets until they can do them with 100% accuracy. We find that the vast majority of mistakes that even high school students make in algebra stem from problems subtracting (and adding) with integers. There are also worksheets that combine both addition and subtraction with integers for greater challenge.
Find the difference.
Simple: 10 - 3 = (positive minus positive) OR -5 - 4 = (negative minus negative)
Advanced: 7 - -9 = (positive minus negative) OR -8 - -7 = (negative minus negative)
We encourage all students to have a full understanding of how negative numbers work before attempting these drills. We also encourage all students entering algebra to be able to complete these drills with 100% accuracy, in less than 5 minutes per page.
