The mathematical foci of this lesson are geometric concepts, location, navigation, direction, and spatial relationships and measurement concepts, using nonstandard units to measure a distance, and the iteration of units, measurement by using the same unit of measure repeatedly to determine the total.

Illluminations: Spinning Tops
Illuminations (National Council of Teachers of Mathematics)

Students measure distances using standard and nonstandard units and record their measurement in various tables.

Illluminations: Beverage Sharing and Serving
Illuminations (National Council of Teachers of Mathematics)

Students determine, using a nonstandard cup or plastic drinking container, the minimum amount of fruit drink needed to serve class members.

Illluminations: A Brownie Bake
Illuminations (National Council of Teachers of Mathematics)

Students determine the amount of each ingredient needed to make brownies, and then they figure out how to divide the brownies evenly among their classmates.

Illuminations: Airport Numbers
Illuminations (National Council of Teachers of Mathematics)

Students are encouraged to relate the numbers to familiar situations, for example, to use the dimensions of the classroom to describe an airplane.
