What (and Perhaps Who) Does the Common Core Math Exclude?

What (and Perhaps Who) Does the Common Core Math Exclude?

Pencil Sharpner

Just what math will be excluded per grade level in Common Core? The following is a list of topics that have be excluded K-3. I have the list of topics up until Grade 8 and can add them if you would like at a later time. It would be interesting to hear from fellow math fanatics. I wish we could go back to Seymour Papert, Marvin Minsky, and Alan Kay's ideas for educational reform.

Here is the list of exclusions brought to you by Common Core. The source of this information is from Catapult Learning.

Excluded from Kindergarten:

  • Writing numbers over 20
  • Skip counting by 2s and 5s
  • Odd vs. even
  • Equal shares
  • Time patterns
  • Data graphs
  • The U.S. Money System (Bills and coins can be used for counting, comparing +, - ).
  • Extensive varieties of patterns.

Excluded from Grade 1:

  • Counting beyond 120
  • Math facts beyond total of 10
  • Fluency with the standard algorithms for addition and subtraction
  • Skip countying by 2s and 5s; odds/even
  • Fraction words beyond half/fourth, quarter
  • Congruent shapes
  • Liquid measurement
  • Telling time beyond the half hour
  • The U.S. Money System (Bills and coins can be used for counting, comparing +, - ).
  • Common measurement units (e.g. feet, cm)
  • Extensive varieties of patterns

Excluded from Grade 2:

  • Rounding to the nearest 10 and 100
  • Adding and subtracting beyond 1000
  • Fluent addition with regrouping > 100
  • Symmetry, Congruence, Similarity
  • Fraction notation, concepts except with words describing parts of a shape
  • Multiplication and Division except for basic idea of equal groups
  • Perimeter
  • Statistics: range, mean, median, mode
  • Probability
  • Weight
  • Area
  • Volume
  • Transformations (Reflections, etc.)
  • Extensive varieties of patterns

Excluded from Grade 3:

  • Decimals
  • Addiion, subtracting with totals > 1000
  • Multiplication and division algorithms (only concepts, foundations, math facts)
  • Muliplicative Comparision (times as much)
  • Long division
  • Denominators other than 2,3,4,6, and 8
  • Comparing two fractions that have different numerators and denominators
  • Customary units for weight such as ounce, pound, cup, pint, quart, gallon
  • Statistics: range, mean, median, mode
  • Probability
  • Symmetry
  • Congruence/Similarity/Transformations
  • Extensive variety of patterns


Were some of these items included under previous curriculums or standards? 


Hi Chuck, 

Yes, those items were included under previous curriculum and standards. In the past, standards were for the most part state governed and would vary from state to state. However, the states who opted into Common Core will be under the umbrella of national standards. 

Public school curriculum is tied to funding (i.e. Race to the Top). Whereas, private schools do not have funding attached many are trying to align with Common Core and new mathematics. For example, we are moving away from Saxton Math and Singapore Math teaching methods.

Kind Regards,



I'm familiar with Common Core but not with other standards which is why I asked. I think it's important to note that Common Core sets a baseline for schools to achieve and they are free (and perhaps encouraged) to exceed them. My children are in 3rd grade and they are already learning mean, median and mode so I know that my school district is doing so. Thanks for putting a list out there of things that aren't included at the various grade levels. I think there is a lot of mis-information about Common Core out there and the more people know the better. A list like this can be taken a school board and allows parents to articulate things that they feel should be included in the curriculum that is chosen for their children. It can also give them things to work on at home if they want to see their kids get ahead.



Hi Chuck,

Thank you for your parental involvement! It really does make a difference! Keep up the awesome work and happy school year to your 3rd graders! It is such a fun grade!

Best Wishes,

Mechelle :)
