Evaluate arithmetic expressions that include an exponent.
Understand that an exponent indicated the number of times that a base is multiplied by itself.
Write the expanded format for a given exponent (repeating multiplication equation that is equivalent to a given exponent).
Evaluate expressions containing positive exponents.
Exponent, Base, Power, Expanded Form
- completed a maze by correctly solving exponents to get to the finish line
- played a game of exponent war. Each student drew two cards one card representing the base and the other card representing the exponent. They solved the exponent and the player with the higher number wins a round.
Recognize a line of symmetry for a 2D figure as a line across that divides a figure into two congruent parts.
Understand that a figure can have multiple lines of symmetry.
Understand that a figure can have no lines of symmetry.
Line of Symmetry, Polygon
- recognized 2D shapes could have more than one line of symmetry or no lines of symmetry
- determined the number of lines of symmetry for various polygons
- created their own shapes and determined the number of lines of symmetry
