Math Facts Color by Number, Within 10

Point to the sign before each problem and say plus or minus out loud. For fact families, use the dots to show how the same three numbers make a plus fact and a minus fact. For color by number, check the color key together before coloring.

Add and subtract within 10, then color the squares by answer to reveal a tree. To add means to put together. To subtract means to take away. Find each answer. The directions on the page read: Add or subtract to solve each problem. Then, color the square with the color for the answer to reveal a tree. The page opens with a worked example, and the answer key shows every answer.

Yes, both. We made it for Kindergarten addition, and the page works the same whether it lands on a kitchen table or a center rotation. At home, most families go through it together and talk the answers out loud, and that talking is where most of the learning happens with fact families and mixed facts. In class it runs well as independent work while you pull a small group. Print one copy or thirty, whichever the day needs.

A fact family is a set of facts that use the same three numbers. The numbers 1, 2 and 3 give 1 + 2 = 3, 2 + 1 = 3, 3 - 1 = 2 and 3 - 2 = 1. The sheets pair a number triangle with dots so children can see why the facts belong together.

When a page mixes plus and minus signs, children have to look at the sign before they work. This builds the habit of reading each problem instead of repeating the same move.

Each answer matches a color, so a wrong answer shows up as a color that does not fit the picture. Children check themselves while they practice facts within 5 or within 10.

The within 5 sheets support K.OA.A.5, and the within 10 sheets support K.OA.A.2.

Most kindergarteners are ready to begin addition in the second half of the school year, typically around January or February. The Common Core standard K.OA.A.1 expects students to represent addition within 10 using objects, fingers, drawings, and equations by the end of kindergarten.

By the end of kindergarten, students should fluently add within 5 (CCSS K.OA.A.5) and solve addition word problems within 10 (K.OA.A.2). They should understand that addition means putting together or adding to, and be able to decompose numbers up to 10 into pairs.

Use physical objects like blocks, buttons, or snacks to make addition concrete. Start with adding within 5, then progress to 10. Printable addition worksheets with pictures help bridge the gap between hands-on manipulatives and abstract number sentences.
