Exponents and Scientific Notation

This topic teaches the concept of exponents through models; we also learn to rewrite such expressions in its standard form, and vice versa. This topic also introduces the concept of scientific notation.

Topic: Square Numbers

  • A square number is the product of a number and itself. A square can be expressed with the exponent 2

  • Use square arrays to model square numbers

  • Any number multiplied by itself, or raised to the 2nd power, is a square number

Topic: Standard Form, Base and Exponents

  • In an, a = base; n = exponent/power

  • The value of an is its standard form

  • Multiply the base n number of times so that it is equal to its standard form

Topic: Scientific Notation

  • To convert from standard form to scientific notation, move the decimal point from the right of the last digit to the right of the first digit

  • After placing the decimal point, drop all the zeros that follow to get the first part

  • Count how many places you move the decimal point. This becomes the value of the exponent, with the base as 10 (the second part)

  • To convert from scientific notation to standard form, first find the expression with powers of 10 using patterns
