= Topic Nine Composing and Decomposing Numbers to 10 = Pacing (Duration of Unit): 1. Makes sense of problems and persevere in solving them. 2. Reason abstractly and quantitatively. 3. Construct viable arguments and critique the reasoning of others. 4. Model with mathematics. 5. Use appropriate tools strategically. 6. Attend to precision.

 * 8. Look for and express regularity in repeated reasoning. ** ||
 * __**Established Goals:**__


 * ** 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 (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.MD.3 ** Classify objects into given categories; count the numbers of objects in each category and sort the categories by count.

__ **Student "I Can" Statements:** __


 * I can take apart numbers less than or equal to 10.
 * I can find the number that is added to 1 through 9 to make 10. I can use objects or drawings to show my answer.
 * I can place objects into categories.
 * I can count the number of objects in categories.
 * I can sort the categories by the number of objects.


 * __Prerequisite Standards:__ **

Any number, measure, numerical expression, algebraic expression, or equation can be represented in an infinite number of ways that have the same value.
 * **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.5 ** Fluently add and subtract within 5. ||
 * __**Big Ideas:**__
 * Equivalence**

There are multiple interpretations of additions, subtractions, multiplication, and division of rational numbers and each operation is related to other operations.
 * Operation Meanings and Relationships **

Mathematics content and practices can be applied to solve problems. || __**Essential Questions:**__
 * Practices, Processes, and Proficiencies **


 * What are different ways to make a number? ||
