The Common Core State Standards for geometry are:

Recognize volume as an attribute of solid figures and understand concepts of volume measurement.

Measure volumes by counting unit cubes, using cubic cm, cubic in, cubic ft, and improvised units.

Relate volume to the operations of multiplication and addition and solve real-world and mathematical problems involving volume.

  • Find the volume of a right rectangular prism with whole-number side lengths by packing it with unit cubes, and show that the volume is the same as would be found by multiplying the edge lengths, equivalently by multiplying the height by the area of the base. Represent threefold whole-number products as volumes, e.g., to represent the associative property of multiplication.

  • Apply the formulas V = l w h and V = b h for rectangular prisms to find volumes of right rectangular prisms with whole-number edge lengths in the context of solving real-world and mathematical problem.
Graph points on the coordinate plane to solve real-word and mathematical problems.

Classify two-dimensional figures into categories based on their properties.

    The product of two numbers is 90. One number is 2.5 times as great as the other. What are the two numbers?

    Tock fills the vending machines in the Doldrums.

    Every Monday he fills the soft drink machine.

    He fills the snack machine every third day.

    He fills the coffee machine every fifth day.

    He fills all three machines on Monday, August 3.

    What is the next date on which he will fill all three machines?

    At Milo's birthday party, 10 of his new friends wore party hats and 8 of his friends used noisemakers.

    There were 12 guests.

    How many of his friends wore a hat and used a noisemaker?

    The Chungs have four children.

    Pam is half as old as Kobo.

    Dan is one third as old as Kobo.

    Kobo is one year older than Nan.

    Nan's age is equal to the sum of Dan's and Pam's ages .

    How old is each of the four children?

    Dan =

    Pam =

    Nan =

    Kobo =
