standard_description: Explain how the definition of the meaning of rational exponents follows from extending the properties of integer exponents to those values, allowing for a notation for radicals in terms of rational exponents. For example, we define 5^(1/3) to be the cube root of 5 because we want (5^(1/3))^(3) = 5(^(1/3))^(3) to hold, so (5^(1/3))^(3) must equal 5.
problem_activity: Stage 2: Numbers 11 - 20
Required Preparation
Materials to Gather
Colored pencils, crayons, or markers
Connecting cubes
Materials to Copy
Blackline Masters
Number Mat 11–20
Number Race Stage 2 Recording Sheet for Writing
Number Race Stage 2 Recording Sheet for Tracing

Narrative
Students take turns rolling a connecting cube onto a number mat and write the number (11–20) they land on, on the recording sheet. Students may want to use colored pencils to write the numbers.
Variation:
Students may use the blackline master that allows them to trace each number to support their number writing skills.
Additional Information
Each group of 2 needs 1 connecting cube.
