K.CC.B.4.a. When counting objects, say the number names in the standard order, pairing each object with one and only one number name and each number name with one and only one object.
No tasks yet illustrate this standard.
K.CC.B.4.b. Understand that the last number name said tells the number of objects counted. The number of objects is the same regardless of their arrangement or the order in which they were counted.
No tasks yet illustrate this standard.
K.CC.B.4.c. Understand that each successive number name refers to a quantity that is one larger.
No tasks yet illustrate this standard.
K.CC.B.5. Count to answer “how many?” questions about as many as 20 things arranged in a line, a rectangular array, or a circle, or as many as 10 things in a scattered configuration; given a number from 1–20, count out that many objects.
K.CC.C.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. Kindergarten - Operations and Algebraic Thinking
K.OA.A. Understand addition as putting together and adding to, and understand subtraction as taking apart and taking from.
K.OA.A.1. Represent addition and subtraction with objects, fingers, mental images, drawingsDrawings need not show details, but should show the mathematics in the problem. (This applies wherever drawings are mentioned in the Standards.), sounds (e.g., claps), acting out situations, verbal explanations, expressions, or equations.
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.NBT. Kindergarten - Number and Operations in Base Ten
K.NBT.A. Work with numbers 11--19 to gain foundations for place value.
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 (e.g., 18 = 10 + 8); understand that these numbers are composed of ten ones and one, two, three, four, five, six, seven, eight, or nine ones.
K.MD.A.2. Directly compare two objects with a measurable attribute in common, to see which object has “more of”/“less of” the attribute, and describe the difference. For example, directly compare the heights of two children and describe one child as taller/shorter.
K.MD.B. Classify objects and count the number of objects in each category.
K.MD.B.3. Classify objects into given categories; count the numbers of objects in each category and sort the categories by count.Limit category counts to be less than or equal to 10.
K.G.A.1. Describe objects in the environment using names of shapes, and describe the relative positions of these objects using terms such as above, below, beside, in front of, behind, and next to.
No tasks yet illustrate this standard.
K.G.A.2. Correctly name shapes regardless of their orientations or overall size.
No tasks yet illustrate this standard.
K.G.A.3. Identify shapes as two-dimensional (lying in a plane, “flat”) or three-dimensional (“solid”).
No tasks yet illustrate this standard.
K.G.B. Analyze, compare, create, and compose shapes.
K.G.B.4. Analyze and compare two- and three-dimensional shapes, in different sizes and orientations, 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).
