Kindergarten Math (Massachusetts Curriculum Frameworks)

Counting and Cardinality (K.CC)

• K.CC.A.1 Count aloud to 100 by ones and by tens.
• K.CC.A.2 Count on from any given number in the known sequence instead of always starting at 1.
• K.CC.A.3 Write numerals 0–20 and use a numeral 0–20 to record how many objects (0 means none).
• K.CC.B.4 Link counting to cardinality (how many).
  • a. Match each object to exactly one number name, saying the names in order.
  • b. Know the last number said tells the total, whatever the arrangement or counting order.
  • c. Know each next number means one more and notice the "one more" pattern when counting objects.
• K.CC.B.5 Count to answer "how many?" for up to 20 objects in a line, array or circle, or 10 scattered; count out 1–20 objects.
• K.CC.C.6 Tell if one group of up to 10 objects has more than, fewer than or the same as another, by matching or counting.
• K.CC.C.7 Compare two numbers from 1 to 10 shown as written numerals.

Operations and Algebraic Thinking (K.OA)

• K.OA.A.1 Show addition and subtraction within 10 with objects, fingers, drawings, sounds, acting out, words or equations.
• K.OA.A.2 Solve addition and subtraction word problems within 10 using objects or drawings.
• K.OA.A.3 Break numbers up to 10 into two parts in more than one way and record each with a drawing or equation.
• K.OA.A.4 Given a number from 1 to 9, find its partner that totals 10 and record it with a drawing or equation.
• K.OA.A.5 Add and subtract within 5 fluently, including with zero.

Number and Operations in Base Ten (K.NBT)

• K.NBT.A.1 Build and break apart numbers 11–19 as ten ones and some more ones, recording with drawings or equations.

Measurement and Data (K.MD)

• K.MD.A.1 Name things about an object that can be measured, such as how long or heavy it is.
• K.MD.A.2 Compare two objects directly on a shared attribute and say which has more or less of it.
• K.MD.B.3 Sort objects into given categories (up to and including 10 in each), count each and order them by count.

Geometry (K.G)

• K.G.A.1 Describe objects using shape names and position words such as above, below, beside and behind.
• K.G.A.2 Name shapes correctly whatever their size or orientation.
• K.G.A.3 Identify shapes as two-dimensional (flat) or three-dimensional (solid).
• K.G.B.4 Compare 2D and 3D shapes of different sizes and orientations using informal language about parts and attributes.
• K.G.B.5 Model real-world shapes by building them from parts and by drawing them.
• K.G.B.6 Put simple shapes together to make larger shapes.
