This packet includes a hands-on activity for practicing addition and subtraction up to ten by having students glue sets of paper squares to represent addition and subtraction equations.
Kindergarten Common Core State Standards Addressed Include:
K.OA.1: Represent addition and subtraction with objects, fingers, mental images, drawings, sounds, acting out the situation, 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 or drawings, and record each decomposition by a drawing or equation.
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.
K.CC.3: Write numbers from 0-20. Represent a number of objects with a written numeral 0-20 (with 0 representing a count of no objects).
K.CC.4: When counting objects, say the number names in the standard order, pairing each object with one and only one number name and each number name with one and only one object.
K.CC.5: Count to answer "how many" questions about as many as 20 things arranged in a line, a rectangular array, or a circle, or as many as 10 things in a scattered configuration; given a number from 1-20, count out that many objects.
