K.CC Counting and Cardinality

• K.CC.A Know number names and the count sequence
  • K.CC.A.1 Count to 100 by ones, fives, and tens.
  • K.CC.A.2 Count forward, by ones, from any given number up to 100.
  • K.CC.A.3 Read, write, and represent numerals from 0 to 20.
• K.CC.B Count to tell the number of objects
  • K.CC.B.4 Understand the relationship between numbers and quantities; connect counting to cardinality. When counting objects: Say the numbers in order, pairing each object with only one number and each number with only one object (one to one correspondence). Understand that the last number said tells the number of objects counted. Understand that each successive number refers to a quantity that is one larger.
  • K.CC.B.5 Count to answer “how many?” Count up to 20 objects in any arrangement. Count up to 10 objects in a scattered configuration. Given a number from 1-20, count out that many objects.
• K.CC.C Compare numbers
  • K.CC.C.6 Identify whether the number of objects in one group from 0-10 is greater than (more, most), less than (less, fewer, least), or equal to (same as) the number of objects in another group of 0-10.
  • K.CC.C.7 Compare two numbers between 0 and 20 presented as written numerals.
  • K.CC.C.8 Quickly identify a number of items in a set from 0-10 without counting (e.g., dominoes, dot cubes, tally marks, ten-frames).

K.OA 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 using objects, fingers, mental images, drawings, sounds (e.g., claps), acting out situations, verbal explanations, expressions (e.g., 2+3), or equations (e.g., 2+3 =).
  • K.OA.A.2 Solve real-world problems that involve addition and subtraction within 10 (e.g., by using objects or drawings to represent the problem).
  • K.OA.A.3 Use objects, drawings, etc., to decompose (break apart) numbers less than or equal to 10 into pairs in more than one way, and record each decomposition (part) by a drawing or an equation (e.g., 5 = 2 + 3 and 5 = 4 + 1).
  • K.OA.A.4 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 10 by using various strategies and manipulatives.

K.NBT Number and Operations in Base Ten

• K.NBT.A Work with numbers 11-19 to gain foundations for place value
  • K.NBT.A.1 Develop initial understanding of place value and the base-ten number system by showing equivalent forms of whole numbers from 11 to 19 as groups of tens and ones using objects and drawings.

K.MD Measurement and Data

• K.MD.A Describe and compare measureable attributes
  • K.MD.A.1 Describe several measurable attributes of a single object, including but not limited to length, weight, height, and temperature. (Vocabulary may include short, long, heavy, light, tall, hot, cold, warm, or cool.)
  • K.MD.A.2 Describe the difference when comparing two objects (side-by-side) with a measurable attribute in common, to see which object has more of or less of the common attribute.
• K.MD.B Classify objects and count the number of objects in each category
  • K.MD.B.3 Classify, sort, and count objects using both measureable and non-measureable attributes such as size, number, color, or shape.
• K.MD.C Work with time and money
  • K.MD.C.4 Understand concepts of time including morning, afternoon, evening, today, yesterday, tomorrow, day, week, month, and year. Understand that clocks, both analog and digital, and calendars are tools that measure time.
  • K.MD.C.5 Read time to the hour on digital and analog clocks.
  • K.MD.C.6 Identify pennies, nickels, and dimes, and know the value of each.

K.G Geometry

• K.G.A Identify and describe shapes (squares, circles, triangles, rectangles, hexagons, cubes, cones, cylinders, and spheres)
  • K.G.A.1 Describe the positions of objects in the environment and geometric shapes in space using names of shapes, and describe the relative positions of these objects.
  • K.G.A.2 Correctly name shapes regardless of their orientations or overall size.
  • K.G.A.3 Identify shapes as two-dimensional (flat) or three-dimensional (solid).
• 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).
  • K.G.B.5 Model shapes in the world by building shapes from components (e.g., sticks and clay balls) and by drawing shapes.
  • K.G.B.6 Compose two-dimensional shapes to form larger two-dimensional shapes.
