Investigations was created to align with and support the 1989 NCTM Standards for School Mathematics in elementary school classrooms. Investigations 2nd edition was revised to continue alignment and support of the 2000 NCTM Principles and Standards for School Mathematics in elementary school classrooms.

See some examples of aligned activities, instructions, and explorations:

 

 

    Chairs
    You walk into a restaurant with a large group of friends. To accommodate you, the restaurant will push a bunch of tables together-but how many tables will be needed to ensure that everyone has a seat? This applet will let you explore that question.

    Cubes
    Fill a box with cubes, rows of cubes, or layers of cubes. The number of unit cubes needed to fill the entire box is known as the volume of the box. Can you determine a rule for finding the volume of a box if you know its width, depth, and height?

    Fraction Game
    This applet allows students to individually practice working with relationships among fractions and ways of combining fractions.

    Ten Frame
    Thinking about numbers using frames of 10 can be a helpful way to learn basic number facts. The four games that can be played with this applet help to develop counting and addition skills.
