Grade: Grade 8  
Type: ODE Model Lesson Plans
Description: Students will review their understanding about numbers and number systems through playing the Number Game. Students will create a list of numbers and based upon the characteristics and properties of the numbers they will earn points. Students will initially play the game using scoring criteria set by the teacher. Then students will have an opportunity to set the scoring criteria and compete against the teacher and their peers.  
Ohio Standards Connection:
Primary Standards, Benchmarks, and Indicators:
Standard:  Number, Number Sense and Operations
  Benchmark: B.  Identify subsets of the real number system.
  Indicator: 2.  Recognize that natural numbers, whole numbers, integers, rational numbers and irrational numbers are subsets of the real number system.
Also aligned to this benchmark is Grade 7 Number, Number Sense and Operations Indicator 3. Describe differences between rational and irrational numbers; e.g., use technology to show that some numbers (raional) can be expressed as terminating or repeating decimals and other (irrational) as non-terminating and non-repeating decimals.
Standard:  Mathematical Processes Standard
  Benchmark: A.  Formulate a problem or mathematical model in response to a specific need or situation, determine information required to solve the problem, choose method for obtaining this information, and set limits for acceptable solution.
   Benchmark: B.  Apply mathematical knowledge and skills routinely in other content areas and practical situations.
