— 3.MD.C.7 Relate area to the operations of multiplication and addition.
c. Use tiling to show in a concrete case that the area of a rectangle with whole-number side lengths a and b + c is the sum of a × b and a × c. Use area models to represent the distributive property in mathematical reasoning.


— GLE0307.7.1 Use information and illustrations to identify the earth’s major landforms and bodies of water


  • Know the names and locations of the continents and oceans
  • Use a compass rose to determine direction
  • Know how to calculate area using multiplication
  • Know that a rectangle can be partitioned into 2 smaller rectangles to calculate area
  • Understand the distributive property and how to use it


  • continent
  • ocean
  • area
  • distributive property
  • square unit


1. red and blue crayon or colored pencil for each child
2. large paper for background (represents the oceans)
3. continents with square units on it
4. recording sheet for each student


TW model using one of the continents.
Glue to the map in the appropriate place.
1. Find a rectangle with the greatest square units on your first continent.
2. Outline your rectangle in red.
3. Label the sides with the length.
4. Find the area of your rectangle in square units. Write an equation to show your work.
5. Partition your rectangle into 2 smaller rectangles.
6. Outline your 2 smaller rectangles in blue.
7. Label the lengths of your 2 smaller rectangles
8. Calculate the area. Write equations to show your work for both rectangles.
9. Underneath each continent, calculate the total area of the large rectangle by finding the area of the 2 smaller rectangles. (distributive property a and b+c is the sum of a x b and a x c)

We Do:

Repeat steps together using 2 more continents.
Glue in correct place on the map.

You Do:

SW complete the remaining continents independently.
SW answer the questions using the information they gathered on their map. See Data Math Sheet.
