Doubles Facts Worksheets | Doubles Up to 20 and Beyond with Answer Key and Plan

Doubles facts worksheets that go past 10 + 10

These doubles facts worksheets are a 13 page packet with 80 questions on adding a number to itself. The worksheet is marked for grades 1 to 4, and the doubles go well beyond 10 + 10, up to double 20.

Students find doubles, check stated doubles, complete addition sentences from a Number Bank and solve short word problems that use a double.

Teachers who need doubles facts practice that stretches past the basic facts will find four sections of 20 questions here, and the doubles facts worksheets come with an answer key and a lesson plan.

What’s on the pages

The worksheet has four sections, and each one has its own heading and directions.

• Multiple choice doubles facts: 20 questions, such as double 20, double 19 and 10 + 10.
• True or false double facts: 20 statements, such as double 7 is 15 (which is wrong), 1 + 1 = 2 and double 20 is 40.
• Complete the doubles fact: 20 questions that use a Number Bank, such as 11 + 11, 3 + 3 and 14 + 14.
• Double problems and word problems: 20 short answer questions, such as 5 apples from one tree and 5 from another, 15 coins saved one week and 15 the next, and if double 4 is 8, what is 4 + 4.

The larger doubles are useful because students begin to see a pattern: double the tens, double the ones, then put them together.

What’s in the download

• Student worksheet: 13 pages
• Answer key: 14 pages, with a short explanation after each answer
• Answer sheet: 4 pages
• Lesson plan: 2 pages

The four parts add up to 33 pages, and everything comes as PDF.

How to use these doubles facts worksheets

The lesson plan is set for 60 minutes. Its objectives are to recall addition doubles quickly and accurately, to identify correct doubles by multiple choice and true or false checks, to complete equations with a Number Bank, and to apply doubles strategies in word problems.

The materials list math counters or Unifix cubes as an optional visual aid, and a whiteboard and markers for the teacher. The plan opens with a 10 minute review of the basic doubles from 1 + 1 to 10 + 10, so the larger doubles build on facts students already know.

Then walk through the sections in order. The true or false section helps students catch close wrong answers, such as double 7 being 15 instead of 14.

The word problems at the end are very short, and each one is a double in disguise. Ask students to say which two numbers are the same before they add.

The answer sheet keeps the worksheet clean for reuse, and the answer key gives a short explanation after every answer.

The double facts true or false section works well as a class warm-up, and the doubles word problems give students a reason to use the facts outside a drill. Teachers can pair the two sections for a short lesson on checking answers.

Where it fits

Use it for math centers, a mental math routine, intervention, homework or a review before a test. Homeschool families can use one section a day.
