Illinois pre-K math standards

Alignments coming soon

IXL's pre-K skills will be aligned to the Illinois Early Learning and Development Standards soon! Until then, you can view a complete list of pre-K standards below. Be sure to check out the unlimited math practice problems in IXL's 42 pre-K skills.


PK.6 Demonstrate and apply a knowledge and sense of numbers, including numeration and operations.

  • PK.6.A Demonstrate beginning understanding of numbers, number names, and numerals.

    • PK.6.A.ECa Count with understanding and recognize "how many" in small sets up to 5.

    • PK.6.A.ECb Use subitizing (the rapid and accurate judgment of how many items there are without counting) to identify the number of objects in sets of 4 or less.

    • PK.6.A.ECc Understand and appropriately use informal or everyday terms that mean zero, such as "none" or "nothing".

    • PK.6.A.ECd Connect numbers to quantities they represent using physical models and informal representations.

    • PK.6.A.ECe Differentiate numerals from letters and recognize some single-digit written numerals.

    • PK.6.A.ECf Verbally recite numbers from 1 to 10.

    • PK.6.A.ECg Be able to say the number after another in the series up to 9 when given a "running start," as in "What comes after one, two, three, fourÂ…?".

  • PK.6.B Add and subtract to create new numbers and begin to construct sets.

    • PK.6.B.ECa Recognize that numbers (or sets of objects) can be combined or separated to make another number.

    • PK.6.B.ECb Show understanding of how to count out and construct sets of objects of a given number up to 5.

    • PK.6.B.ECc Identify the new number created when small sets (up to 5) are combined or separated.

    • PK.6.B.ECd Informally solve simple mathematical problems presented in a meaningful context.

    • PK.6.B.ECe Fairly share a set of up to 10 items between two children.

  • PK.6.C Begin to make reasonable estimates of numbers.

    • PK.6.C.ECa Estimate number of objects in a small set.

  • PK.6.D Compare quantities using appropriate vocabulary terms.

    • PK.6.D.ECa Compare two collections to see if they are equal or determine which is more, using a procedure of the child's choice.

    • PK.6.D.ECb Describe comparisons with appropriate vocabulary, such as "more", "less", "greater than", "fewer", "equal to", or "same as".

PK.7 Explore measurement of objects and quantities.

  • PK.7.A Measure objects and quantities using direct comparison methods and nonstandard units.

    • PK.7.A.ECa Compare, order, and describe objects according to a single attribute.

    • PK.7.A.ECb Use nonstandard units to measure attributes such as length and capacity.

    • PK.7.A.ECc Use vocabulary that describes and compares length, height, weight, capacity, and size.

    • PK.7.A.ECd Begin to construct a sense of time through participation in daily activities.

  • PK.7.B Begin to make estimates of measurements.

    • PK.7.B.ECa Practice estimating in everyday play and everyday measurement problems.

  • PK.7.C Explore tools used for measurement.

    • PK.7.C.ECa With teacher assistance, explore use of measuring tools that use standard units to measure objects and quantities that are meaningful to the child.

    • PK.7.C.ECb Know that different attributes, such as length, weight, and time, are measured using different kinds of units, such as feet, pounds, and seconds.

PK.8 Identify and describe common attributes, patterns, and relationships in objects.

  • PK.8.A Explore objects and patterns.

    • PK.8.A.ECa Sort, order, compare, and describe objects according to characteristics or attribute(s).

    • PK.8.A.ECb Recognize, duplicate, extend, and create simple patterns in various formats.

  • PK.8.B Describe and document patterns using symbols.

    • PK.8.B.ECa With adult assistance, represent a simple repeating pattern by verbally describing it or by modeling it with objects or actions.

PK.9 Explore concepts of geometry and spatial relations.

  • PK.9.A Recognize, name, and match common shapes.

    • PK.9.A.ECa Recognize and name common two- and three-dimensional shapes and describe some of their attributes (e.g., number of sides, straight or curved lines).

    • PK.9.A.ECb Sort collections of two- and three-dimensional shapes by type (e.g., triangles, rectangles, circles, cubes, spheres, pyramids).

    • PK.9.A.ECc Identify and name some of the faces (flat sides) of common three-dimensional shapes using two-dimensional shape names.

    • PK.9.A.ECd Combine two-dimensional shapes to create new shapes.

    • PK.9.A.ECe Think about/imagine how altering the spatial orientation of a shape will change how it looks (e.g., turning it upside down).
