It works! Kids will master their math skills, having fun the whole time.

Our individualized learning program is designed based on developmental theory, evidenced-based early number interventions, and Maria Montessori’s early mathematics approach.

Schedule a Demo

Here's how it works.

  • When children begin playing Math Shelf, they take a placement test that assigns them to games and activities that match their knowledge and skill level. 
  • Teachers schedule students to play Math Shelf in class for 10 minutes, twice per week. Each student will receive sequenced and adaptive instruction.
  • Math Shelf has over 1,500 games and activities to keep students engaged throughout the year. 
How Math Shelf Works

The Skills Math Shelf Teaches

Your Pre-K & Kindergarten students will learn a whole lot of math!


Pre-Math Skills

  • Names and matches primary and secondary colors.
  • Matches items by size, shape, and orientation
  • Sorts objects into 2, 3, and 4 categories
  • Orders up to 5 items from smallest to largest
  • Counts with 1-to-1 correspondence
  • Identifies similarities and differences
  • Classifies objects

Counting & Cardinality

  • Counts to 100 by ones, fives, and tens
  • Counts to answer "how many?" questions
  • Understands that the last number name tells how many objects were counted
  • Counts forward & backwards beginning from a given number to 100
  • Writes numbers from 0 to 1,000
  • Identifies whether the number of objects in one group is greater than, less than, or equal to the number of objects in another group
  • Compares numbers between 1 and 100 when presented as written numerals
  • Reads and writes numerals, and represents a number of objects with a written numeral

Operations & Algebraic Thinking

  • Decompose numbers less than or equal to 10 into pairs in more than one way
  • Represent addition and subtraction with objects, fingers, mental images, and drawings up to 10
  • Fluently add and subtract within 10
  • Solve addition and subtraction word problems within 20
  • Add and subtract within 20 by using fluency facts for addition-subtraction within 10
  • Understand the meaning of the equal sign, and determine if equations involving addition and subtraction are true or false
  • Determine the unknown whole number in an addition or subtraction equation

Numbers & Operations in Base Ten

  • Compose and decompose numbers from 11 to 19 into tens and ones
  • Understand place value of a three-digit number and can identify hundreds, tens and ones place
  • Compare two, two-digit numbers using symbols >, =, <
  • Given a two-digit number, mentally find 10 more or 10 less than the number
  • Add within 100 using concrete models that represent place value
  • Subtract multiples of 10 in the range 10-90 using concrete models, drawings, and place value strategies


  • Weight. Measure and record the weight of various objects, and add smaller objects to calculate the weight of larger objects
  • Temperature. Measure and record the temperature, and associate thermometer readings with seasons and weather
  • Time. Tell and write time in hours and half-hours using analog and digital clocks
  • Money. Solve problems involving dollar bills, quarters, dimes, nickels, and pennies, using $ and ¢ symbols appropriately
  • Length. Order objects by length; compare the lengths, and express the length of an object as a whole number of units
  • Data. Organize, represent, and interpret data with up to three categories; ask and answer questions about how many more or less are in one category than in another


  • Correctly name shapes regardless of their orientations or size
  • Identify shapes as two-dimensional or three-dimensional
  • Analyze and compare two- and three-dimensional shapes, in different sizes and orientations
  • Identify and name shapes in one's environment
  • Compose simple shapes to form larger shapes (2 triangles to form a rectangle, 3 triangles to form a trapezoid, 5 triangles to form a pentagon, etc.)
  • Fractions. Partition circles and rectangles into two, three, four, five, and six equal shares. Describe shares using the words halves, thirds, fourths, etc.
  • Count shape sides and angles and distinguish between different shape's defining attributes

94% of students master the Common Core standards by playing Math Shelf just 20 minutes per week.
