Lesson objective: Solve problems by creating and counting various arrangements of the same number.

This lesson provides an opportunity for students to apply their knowledge and understanding of counting to a real-life situation. Students are asked to create different arrangements of tickets that meet certain criteria but always have the same number of tickets.

Key Concept students will use: 

  • Arranging a set of objects in different ways does not change the number of objects counted.

Skills students will use:

  • rote counting to 10 (Grade K, Unit 1)
  • one-to-one correspondance (Grade K, Unit 1)
  • counting sets of objects to answer the question "How many?"

Students engage in Mathematical Practice 6 (Attend to precision) as they consider and carefully create and count multiple arrangements of the 10 tickets.

Key vocabulary: 

  • arrangement
  • fair (as in a State Fair)
  • tickets

Special materials needed:

  • cubes (for modeling and counting)
