    • Represent numbers - up to 10 (P-C.13)

PK.M 2 Number Relationships and Operations

• PK.M 2.a Children learn to use numbers to compare quantities and solve problems.

  • PK.M 2.a.1 Use counting to compare two sets of objects and to determine which set has more, less, or the same than the other

    • More (P-E.1)
    • Fewer and more - compare by counting (P-E.4)
    • Fewer and more - compare in a mixed group (P-E.5)

  • PK.M 2.a.2 Understand that adding one or taking away one changes the number in a group of objects by exactly one

    • One more and one less with pictures - up to 10 (K-C.20)

  • PK.M 2.a.3 Use toys and other objects as tools to solve simple addition and subtraction problems with totals smaller than ten

    • Add with pictures - sums up to 5 (K-J.6)
    • Subtract with pictures - numbers up to 5 (K-L.3)

PK.M 3 Classification and Patterning

• PK.M 3.a Children learn to order and sort objects by common attributes, to identify patterns, and to predict the next sequence in a pattern.

  • PK.M 3.a.1 Sort objects by more than one attribute (e.g., color and shape) into two or more groups

    • Different (P-G.1)
    • Same (P-G.2)
    • Same and different (P-G.3)
    • Classify shapes by color (P-G.4)

  • PK.M 3.a.2 Sort sets of objects by one characteristics, then sort by a different characteristics and explain the sorting rules (e.g., "These are all of the red ones, but these are all of the big ones")

  • PK.M 3.a.3 Extend sequential patterns and replicate these patterns using different materials or modes (e.g., on being told a pattern, replicating the pattern with manipulatives)

    • Shape patterns (K-I.3)

  • PK.M 3.a.4 Identify the core unit of sequentially repeating patterns (i.e., that set of characteristics or items that repeat)

    • Complete a pattern (K-I.5)

  • PK.M 3.a.5 Replicate and extend simple growing (or enlarging) patterns

    • Find the next row in a growing pattern (K-I.8)

PK.M 4 Measurement, Comparison, and Ordering

• PK.M 4.a Children learn to measure objects by their various attributes (length, height, weight, volume) and to use differences in attributes to make comparisons.

  • PK.M 4.a.1 Order (or seriate) four or more items by decreasing or increasing a relative attribute when differences are perceptually clear (e.g., arranging a rock collection from the largest to the smallest)

  • PK.M 4.a.2 Use some appropriate tools to measure different attributes (e.g., choosing a scale for weight and a cup for volume)

  • PK.M 4.a.3 Use measurement language to describe the attributes of objects (e.g., "This is three-blocks long.")

    • Long and short (P-I.1)
    • Tall and short (P-I.2)
    • Wide and narrow (P-I.3)
    • Light and heavy (P-I.4)
    • Holds more or less (P-I.5)
    • Compare size, weight, and capacity (P-I.6)
    • Measure length with objects (K-U.7)

PK.M 5 Geometry and Spatial Sense

• PK.M 5.a Children learn to identify shapes and their attributes, solve problems using shapes, and explore the positions of objects in space.

  • PK.M 5.a.1 Describe and compare shapes using their attributes (e.g., "a triangle has three sides, but a square has four.")

    • Count sides and corners (K-W.13)
    • Compare sides and corners (K-W.14)

  • PK.M 5.a.2 Combine and separate shapes to make other shapes (e.g., using two triangles to make a square)

  • PK.M 5.a.3 Build more complex models of buildings, structures, or areas (e.g., their classroom or playground) with three-dimensional shapes, such as building blocks

  • PK.M 5.a.4 Correctly name familiar shapes (e.g., circle, triangle, and square) and less familiar shapes (e.g., hexagon, trapezoid, and rhombus)

    • Squares (P-K.4)
    • Circles, squares, and triangles (P-K.6)
    • Name the two-dimensional shape (1-W.1)

  • PK.M 5.a.5 Correctly name some three- dimensional shapes (e.g., cube, cone, cylinder)

    • Name the solid shape (P-L.2)

  • PK.M 5.a.6 Understand and use language related to directionality, order, and the position of objects, such as "up, ""down," "in front," and "behind"

    • Inside and outside (P-F.1)
    • Left and right (P-F.2)
    • Left, middle, and right (P-F.3)
    • Top and bottom (P-F.4)
    • Above and below (P-F.6)
