Kindergarten Math (Iowa Core)

Counting and Cardinality (CC)

• K.CC.A.1 Count aloud to 100 in ones and in tens.
• K.CC.A.2 Count on from any given number up to 100, not only from 1.
• K.CC.A.3 Write numerals from 0 to 20 and use them to show how many objects are in a set.
• K.CC.IA.A.1 Iowa standard: count backward by ones from 20 down to 0.
• K.CC.IA.A.2 Iowa standard: count backward starting from any number from 0 to 20.
• K.CC.B.4 Show the principles of counting (a–e): stable order, one-to-one matching, cardinality, conservation and that each next number is one more.
• K.CC.B.5 Count up to 20 objects set out in a line, an array, a circle or scattered.
• K.CC.IA.B.1 Iowa standard: recognize small quantities up to 5 at a glance without counting (subitizing).
• K.CC.C.6 Compare two groups of up to 10 objects and say whether one has more, fewer or the same.
• K.CC.C.7 Compare two written numerals between 1 and 10.

Operations and Algebraic Thinking (OA)

• K.OA.A.1 Show addition and subtraction situations in several different ways.
• K.OA.A.2 Add and subtract within 10 and solve the listed types of word problems using objects or drawings.
• K.OA.A.3 Break numbers up to 10 into pairs in more than one way and record each with a drawing or equation.
• K.OA.A.4 Find the partner that brings any number from 1 to 9 up to 10.
• K.OA.A.5 Add and subtract within 5 fluently.

Number and Operations in Base Ten (NBT)

• K.NBT.A.1 Build and break apart numbers from 11 to 19 as ten ones and some more ones.

Measurement and Data (MD)

• K.MD.A.1 Describe attributes of objects that can be measured, such as length or weight, using everyday words.
• K.MD.A.2 Compare two objects directly by a shared attribute and say which has more or less of it.
• K.MD.B.3 Sort objects into given categories, count each category and order them by count (10 or fewer per category).
• K.MD.IA.B.1 Iowa standard: identify a penny and count collections of pennies up to 20.

Geometry (G)

• K.G.A.1 Name shapes seen in the environment and describe where they are using position words.
• K.G.A.2 Name shapes correctly whatever their size or orientation.
• K.G.A.3 Say whether a shape is flat (two-dimensional) or solid (three-dimensional).
• K.G.B.4 Analyze and compare 2D and 3D shapes of different sizes and orientations using informal language.
• K.G.B.5 Model real-world shapes by building them from components and by drawing them.
• K.G.B.6 Put simple shapes together to make larger shapes.
