Number bracelets provide concrete practice for determining all the combinations of each number from 1 to 10. This ability to compose and decompose numbers in a variety of ways lays the foundation for fluency with addition and subtraction facts.
Teacher notes include:
• Instructions and labels for making the number bracelets
This is a DIY project and additional materials (chenille stems and pony beads) are required to make the bracelets
• Instructions for using the bracelets in a variety of ways in whole group, small group, and workstation settings with suggestions for differentiation
• Prompts for using with a math journal to record all combinations of the numbers from 1 to 10
• Missing addend equation cards for hands-on practice with the number bracelets

Common Core Alignment
K.OA.1—Represent addition and subtraction with objects, fingers, mental images, drawings, sounds (e.g., claps), acting out situations, verbal explanations, expressions, or equations.
K.OA.2—Solve addition and subtraction word problems, and add and subtract within 10, e.g., by using objects or drawings to represent the problem.
K.OA.3—Decompose numbers less than or equal to 10 into pairs in more than one way, e.g., by using objects drawings, and record each decomposition by a drawing or equation (e.g., 5 = 2.+ 3 and 5 = 4 + 1).
K.OA.4—For any number from 1 to 9, find the number that makes 10 when added to the given number, e.g., by using objects or drawings, and record the answer with a drawing or equation.
K.OA.5—Fluently add and subtract within 5.
1.OA.6—Add and subtract within 20, demonstrating fluency for addition and subtraction within 10.
1.OA.7—Understand the meaning of the equal sign, and determine if equations involving addition and subtraction are true or false. For examples, which of the following equations are true and which are false? 6 = 6, 7 = 8 - 1, 5 + 2 = 2 + 5, 4 + 1 = 5 + 2.
1.OA.8—Determine the unknown whole number in an addition or subtraction equation relating three whole numbers. For example, determine the unknown number that makes the equation true in each of the equations 8 + ? = 11, 5 = - 3, 6 + 6 = .
