# Worksheets for Elementary Math: Doubles Addition

Explaining the Addition of Doubles to Young Mathematicians

When teachers first introduce children to mathematics in kindergarten and first grade, each core concept must be presented thoroughly and with as comprehensive of an explanation as possible. For this reason, it's important to explain the addition of doubles to young mathematicians early in the process of teaching addition in order to ensure they properly understand the fundaments of basic arithmetic.

Although there are a variety of teaching tools such as printable doubles addition worksheets and counters, the best way to demonstrate the concept of doubles addition is to walk students through the addition of each number one through 10 to itself through the use of visual aids.

By walking students through each addition set through tactile demonstration (say for instance using buttons as counters), teachers are able to practically display the concepts of basic mathematics in a way that young children can comprehend.

## The Ideal Curriculum for Early Addition

There are a variety of hypotheses about the best way to teach kindergarten and first-grade students basic addition, but most of them point to using concrete objects like buttons or coins to demonstrate basic addition facts for numbers from one through 10.

Once the child understands the concept of asking questions like "If I have 2 buttons and I get 3 more buttons, how many buttons do I have?" it's time to move the student to pen-and-paper examples of these questions in the form of basic math equations.

Students should then practice writing out and solving all equations for numbers one through 10 and study graphs and charts of these number facts that will help them when they begin learning more complicated addition later in their education.

By the time students are ready to move on to the concept of doubling a number—which is the first step to understanding multiplication in first and second grades—they should fundamentally grasp regular addition of numbers one through 10.

## Worksheet Instructions and Utility in Teaching

Allowing students to practice simple addition, especially of doubles, will give them the chance to memorize these simple calculations. However, it's important when first introducing students to these concepts to provide them with tactile or visual aids to help calculate the sums.

Tokens, coins, pebbles, or buttons are great tools for demonstrating the practical side of math. For instance, a teacher might ask a student, "If I have two buttons then I buy two more buttons, how many buttons will I have?" The answer, of course, would be four, but the student could walk through the process of adding these two values by counting out two buttons, then another two buttons, then counting all of the buttons together.

For the worksheets below, challenge your students to complete the exercises as quickly as possible with and without the use of counters or counting tools. If a student misses any of the questions once he or she hands it in for review, set aside time to work individually with the student to demonstrate how he or she arrived at his or her answer and how to illustrate the addition with visual aides.
