Kindergarten Math (Montana Content Standards)

Counting and Cardinality (CC)

• MT.K.CC.1 Count flexibly to 100 by ones and by tens.
• MT.K.CC.2 Count forward from a given number in the known sequence.
• MT.K.CC.3 Write numbers 0–20 and show a number of objects with a numeral 0–20.
• MT.K.CC.4 Link counting to cardinality: each next number names a quantity one larger.
• MT.K.CC.5 Count to answer "how many?" in different arrangements and build a set of up to 20.
• MT.K.CC.6 Say whether one group has more, fewer or the same number of objects as another.
• MT.K.CC.7 Compare two written numerals from 1 to 10.

Operations and Algebraic Thinking (OA)

• MT.K.OA.1 Show addition and subtraction in several ways.
• MT.K.OA.2 Solve addition and subtraction word problems within 10, including Montana Indigenous and local cultural contexts.
• MT.K.OA.3 Break numbers 10 or less into pairs in several ways.
• MT.K.OA.4 For any number 1–9, find the number that makes 10.
• MT.K.OA.5 Add and subtract within 5 flexibly and accurately.
• MT.K.OA.6 Recognize that order does not matter when adding (commutative property).

Number and Operations in Base Ten (NBT)

• MT.K.NBT.1 Build and break apart numbers 11–19 into tens and ones in several ways, recording with drawings or equations.

Measurement and Data (MD)

• MT.K.MD.1 Describe several attributes of one object.
• MT.K.MD.2 Compare two objects directly by a shared attribute using comparison words.
• MT.K.MD.3 Classify, count and sort objects into categories, including Montana Indigenous and local cultural contexts.
• MT.K.MD.4 Describe the features of coins and name them.
• MT.K.MD.5 Talk about time using days, months, years and seasons.

Geometry (G)

• MT.K.G.1 Describe where objects are in the environment, including Montana Indigenous and local cultural contexts.
• MT.K.G.2 Name shapes whatever their orientation or size.
• MT.K.G.3 Say whether shapes are two-dimensional or three-dimensional.
• MT.K.G.4 Analyze and compare 2D and 3D shapes using informal language and attributes.
• MT.K.G.5 Model shapes in the environment, including Montana Indigenous and local cultural contexts.
• MT.K.G.6 Put simple shapes together to make larger shapes.
