                    PreKindergarten Overview

                               Mathematics

     


     Students enrolled in a prekindergarten math class in Wicomico County Public Schools can expect to learn how to do the following:

     

     

                                            Numbers and Counting

    Know number names and the count sequence

    • Build concept of number
    • Show an understanding of quantity
    • Construct relationships based on quantity
    • Use classroom experiences to indicate same, more, or less
    • Count and discuss quantity
    • Use concrete materials to build sets 0 to 10
    • Match a numeral to a set 0 to 10
    •  Count to 20
    • Identify written numerals to 10

     

                                      Operations and Algebraic Thinking

    Understand addition as putting together and subtraction as taking apart

     

    • Represent simple addition and subtraction problems with objects
    • Decompose a quantity to 10 into pairs in more than one way

     

                                       Measurement and Data

           Recognize and use measurement attributes 

    • Demonstrate an understanding of: bigger, smaller, longer, shorter, lighter, heavier, shorter, taller
    • Compare and describe objects according to a single attribute

     

                                                   Geometry

     

     Recognize and use the attributes of plane and solid geometric figures          

    • Sort objects by one attribute such as: shape, color, size, weight, or length
    • Name the attributes of plane figures such as: shape, color, size, number of sides
    • Match triangles, circles, squares, rectangles, hexagons, and octagons of various sizes
    • Identify shapes in the environment

     

                                       Math Questioning

     

    Below are some ideas for asking questions about math.

     

                                 Numbers and Counting       

    • How far can you count?
    • Is your set the same size as any other sets? How do you know?
    • Do you have more or less than 5 items? How do you know?
    • How many would you have if I gave you one more?
    • How many would you have if I took one away?
    • How does your set compare to a set of 3 objects? Are there more or less?
    • If I gave you two sets of connecting links, how many links would you have altogether?
    • How do you know which set has more?
    • How do you know which set has less?
    • Is there a big difference or a small difference between the two sets?
    • How many more objects does the larger set contain?
    • How could the sets be changed so they have the same amount?
    • What is the total number of cubes in both of the sets?

     

                              Measurement and Data
                                                                     

    • How do you know your object is smaller than this one?
    • Can you find an object that is bigger than the one you chose?
    • Can you find an object that is smaller than the one you chose? How do you know the object is smaller?
    • Which object is the longest (shortest)? Show me how we can check that to be sure.
    • What is longer (shorter) than the objects you have chosen?
    • What object is heavier than this one? How do you know it is heavier?

                                      Geometry

    • Describe the objects. How will you sort them?
    • Why did you decide to put the _____ there?
    • Why are these objects sorted this way?
    • Where would this object belong? How do you know?
    • Can you think of anything else that could belong in this group?
    • Why can't the _____ go in this group?
    • Is there anything else that could go inside this group?
    • Can you think of a different way to sort these objects?
    • How many ways can you sort these objects?
