Kindergarten+OA

= Kindergarten Operations and Algebraic Thinking Domain = The Operations and Algebraic Thinking domain spans grades K-5. Concepts learned in the Counting and Cardinality domain form the foundation for Operations and Algebraic Thinking and Numbers and Operations (Base Ten). For kindergarten students, there is only one cluster in the Operations and Algebraic Thinking domain:
 * Understand addition as putting together and add to, and understand subtraction as taking apart and taking from

 = What Your Child Will Learn = __ Addition and Subtraction Concepts __  **Kindergarten Operations and Algebraic Thinking Math Vocabulary** //**subtract**:// take away one quantity from another //**compose**:// to put decomposed numbers back together. For example, 19 and 9 make 18 or 9+9=18. //**decompose**:// to separate numbers into smaller parts. For example, 18 is 10 and 8 or 18=10+8. //**equation**:// an addition or subtraction sentence //**sum**:// how many there are in all in an addition sentence //**difference**:// how many are left in a subtraction sentence //**equals sign**:// the sign between the numbers being added or subtracted and the sum or difference (=) //**plus sign**:// the sign between the numbers being added in an addition sentence (+) //**minus sign**:// the sign between the numbers being subtracted in a subtraction sentence (-)  = Suggestions for At-Home Activities =  = Optional Interactive Learning Experiences =
 * represent addition and subtraction in different ways (with objects, fingers, drawings, sounds (e.g., claps), verbal explanations, equations, etc.)
 * solve addition and subtraction word problems within 10
 * decompose numbers less than or equal to 10 into pairs (e.g., 5=4+1 and 5=3+2 and 5=0+5)
 * find the number that makes ten when added to a given number (e.g., 2+ __?__ =10)
 * fluently add and subtract within 5
 * //add//**//:// join together two or more numbers
 * At the store ask, "I picked out 4 oranges and you picked out 5 apples. How many fruits do we have altogether?" or "We need 6 pieces of chicken, but this package only has 4 in it. How many more pieces of chicken do we need?"
 * Have your child keep score when you play cards or active games together. Many board games require math skills as well as score keeping.
 * Use a calendar to count up or back to a special event such as a vacation, birthday, or holiday.
 * How many ways can you show the sum of ten? (0+10=10, 1+9=10, 2+8=10, etc.) Use Uno cards to show the ways you can decompose the number 10.
 * Scatter magnetic numbers on the refrigerator. Make addition and subtraction math sentences.
 * Solve problems with materials in your home such as, "There were 5 bananas in a bunch this morning. Now there are only 3. How many were eaten?"
 * Create a "hundred chart" on the floor tiles in your kitchen, with sidewalk chalk on the driveway, or with yarn on the rug. This site offers activity ideas from very basic number identification and sequence to factors and fractions!
 * Shuffle a deck of cards and deal 6 cards to each player. Deal 6 more cards face up in the center, and stack the remaining cards face down in a draw pile. The 6 face up cards represent six answers. From the cards in their hand, each player tries to find two cards whose sum or difference matches one of the answer cards. (Ace=1, Jack=11, Queen=12, King=13). If the first player makes a match, he announces the equation, picks up the answer card, and stacks it face up on top of his two cards in a bundle in front of him. Then he draws 2 new cards from the draw pile. If he is unable to make a match, he places one of his cards face up in line with the answer cards and draws a replacement from the draw pile. The second player has two options: to match any of the answer cards or to steal another player's bundle by making an equation that matches the bundle's top card. (The bundle's other two cards become part of the player's hand.) Continue until cards run out or no one can produce an equation. To calculate scores, players count up the number of cards in their bundles and subtract the number of cards still in their hands.
