K.CC.5 Count to answer "how many?" up to 20 concrete or pictorial objects arranged in a line, a rectangular array, or a circle, or as many as 10 objects in a scattered configuration; given a number from 1 to 20, count out that many objects.
K.CC.6 Identify whether the number of objects in one group is greater than, less than, or equal to the number of objects in another group, (e.g., by using matching and counting strategies.) Include groups with up to ten objects.
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.) Refer to shaded section of Table 1 for specific situation types.
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)).
Work with numbers 11–19 to gain foundations for place value.
K.NBT.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 (e.g., 10 + 8 = 18 and 19 = 10 + 9); [Graphic cannot be reproduced]); understand that these numbers are composed of ten ones and one, two, three, four, five, six, seven, eight, or nine ones.
K.G.4 Analyze and compare two- and three-dimensional shapes, in different sizes and orientations (position and direction in space), using informal language to describe their similarities, differences, parts (e.g., number of sides and vertices/"corners") and other attributes (e.g., having sides of equal length).
