Differentiated addition activities for independent and small group centers. The students can use the cards in several ways. They can write using a dry erase marker on the cards, use manipulatives then create the number sentence, or only use manipulatives. I have attached a large blank ladybug counting mat so the children can place the manipulatives on a each wing to see the composing or decomposing of the number. The blue cards are for students who are still mastering the Kindergarten standard, and the green cards are for children who are ready for higher numbers. There is a color by code for both levels.
Common Core Standards:
K.OA.A.1 : Represent addition and subtraction with objects, fingers, mental images, drawings1, sounds (e.g., claps), acting out situations, verbal explanations, expressions, or equations.
K.OA.A.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.A.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.A.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.A.5 : Fluently add and subtract within 5. CCSS.Math.Content.K.NBT.A.1 Compose and decompose numbers from 11 to 19 into ten ones and some further ones, e.g., by using objects or drawings, and record each composition or decomposition by a drawing or equation (such as 18 = 10 + 8); understand that these numbers are composed of ten ones and one, two, three, four, five, six, seven, eight, or nine ones.
