Mathematical Practices: 1. Make 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. 7. Look for and make use of structure. 8. Look for and express regularity in repeated reasoning. ||Common Core Mathematics||Kindergarten||Mathematical Practices|||K.CC.1. Count to 100 by ones and by tens.||Common Core Mathematics||Kindergarten||Counting And Cardinality||Know Number Names And The Count Sequence|||K.CC.3. Write numbers from 0 to 20. Represent a number of objects with a written numeral 0-20 (with 0 representing a count of no objects).||Common Core Mathematics||Kindergarten||Counting And Cardinality||Know Number Names And The Count Sequence|||K.CC.4. Understand the relationship between numbers and quantities; connect counting to cardinality.||Common Core Mathematics||Kindergarten||Counting And Cardinality||Count To Tell The Number Of Objects|||K.CC.7. Compare two numbers between 1 and 10 presented as written numerals.||Common Core Mathematics||Kindergarten||Counting And Cardinality||Compare Numbers|||K.OA.1. Represent addition and subtraction with objects, fingers, mental images, drawings2, sounds (e.g., claps), acting out situations, verbal explanations, expressions, or equations.||Common Core Mathematics||Kindergarten||Operations And Algebraic Thinking||Understand Addition As Putting Together And Adding To, And Under- Stand Subtraction As Taking Apart And Taking From|||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.||Common Core Mathematics||Kindergarten||Operations And Algebraic Thinking||Understand Addition As Putting Together And Adding To, And Under- Stand Subtraction As Taking Apart And Taking From|||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).||Common Core Mathematics||Kindergarten||Operations And Algebraic Thinking||Understand Addition As Putting Together And Adding To, And Under- Stand Subtraction As Taking Apart And Taking From|||K.OA.5.
