The student will investigate and describe concepts of positive exponents and perfect squares. 
Essential Knowledge and Skills
  • Recognize and describe patterns with exponents that are natural numbers, by using a calculator.
  • Recognize and describe patterns of perfect squares not to exceed 20 squared, by using grid paper, square tiles, tables, and calculators.
  • Recognize powers of ten by examining patterns in a place value chart: 10^4 = 10,000, 10^3 = 1000, 10^2 = 100, 10^1 = 10, 10^0=1.
Essential Understandings
  • What does exponential form represent? Exponential form is a short way to write repeated multiplication of a common factor such as
    5 x 5 x 5 x 5 = 5^4
  • What is the relationship between perfect squares and a geometric square? A perfect square is the area of a geometric square whose side length is a whole number.
