Doubles and Near Doubles Addition & Subtraction Within 20 | Doubles Plus 1 & 2 | Math Worksheets

Vertical math worksheets to help you teach doubles and near doubles addition and subtraction facts within 20. Doubles and near doubles are a useful strategy to build math fact fluency in 1st and 2nd grade.

Kids usually learn their doubles facts easier (6+6, 7+7, 8+8, etc.), and once they know those, they can use them to work out related facts fast. 

With doubles plus one, doubles plus two, and doubles minus one, students learn to adjust from a fact they already know.

The pack includes:

• Doubles
• Doubles Plus One
• Doubles Plus Two
• Doubles Minus One
• Mixed Doubles and Doubles Plus One
• Mixed Doubles and Doubles Minus One
• Mixed Doubles and Doubles Plus Two
• Mixed Doubles, Doubles Plus One, and Doubles Plus Two

Worksheets move from single-strategy practice into mixed review, so kids aren't just drilling one skill in isolation; they're learning to recognize which strategy fits a given problem.

Use for morning work, math centers, homework, intervention groups, or timed fact practice. Black and white, print-and-go format.

Answer keys included.
