What Makes This Practice Different?

These worksheets focus specifically on adding doubles: addition facts in which the same number is used twice, such as 4 + 4 or 7 + 7. That keeps the practice tightly focused on one high-value addition pattern instead of mixing unrelated fact types.

Working repeatedly with doubles helps students notice equal addends, connect the addends to a known total, and build faster recall of basic addition facts.

This printable resource includes 10 worksheets with 80 questions in total, plus matching answer keys.

Both A4 and US Letter versions are included so teachers, parents, tutors, and homeschool families can print the format that best matches their setup.

How to Add Doubles

A doubles fact adds a number to itself. Students can read the two equal addends, identify the known double, and write the total.

For example, 6 + 6 = 12. Once students recognize that both addends are 6, they can use the known double of 6 rather than counting each quantity from the beginning.

Encourage students to say the complete fact aloud as they work: “double 6 is 12.” This links the visual equation to the fact they are learning to recall.

Use Known Doubles Facts

Known doubles can become anchor facts for later addition work. Fluency with facts such as 3 + 3, 5 + 5, and 8 + 8 gives students a stable set of totals they can recognize quickly.

The repeated format in this resource is useful for short fluency sessions, independent practice, intervention, homework, or review after doubles have been introduced.
