Continuum of Activities

Continuum of Activities

The list below represents a continuum of activities: resources categorized by Standard/Eligible Content that teachers may use to move students toward proficiency. Using LEA curriculum and available materials and resources, teachers can customize the activity statements/questions for classroom use.

This continuum of activities offers:

  • Instructional activities designed to be integrated into planned lessons
  • Questions/activities that grow in complexity
  • Opportunities for differentiation for each student’s level of performance

  1. 40p3q2; Things to look for in the answer - 8 times any prime number except 7, must have 1 or more p's, exactly 2 q's, may have any other letter but r
  1. Various answers including: 180, x2, y3, z4; things to look for - none of the numbers/letters can exceed: two - 2's, two - 3's, one - 5, two - x's, three - y's, four - z's; at least one of the four answers must contain the max for each group
  1. Various answers including: 5x2, 15x2y2, 20x3z; things to look for - Each answer must have exactly one factor of 5 and two x’s; At least one answer, but not more than two answers, must have two factors of 2, and one factor of 3, three factors of x, two factors of y, and one factor of z
  1. The LCM of x and x+1 equals x2 + x because any two consecutive integers do not share any prime factors.
