a GREAT Valentine's Day activity
(Use Sudoku to engage your students while evaluating and solving exponential expressions and equations)
Students evaluate or solve the exponential expressions or equations to discover a code that sets up a sudoku puzzle. Once the math is complete, the sudoku challenge can begin.
These activities are great for differentiation. They also keep your early finishers engaged while other students complete the assignment. The puzzles can be optional, but provide critical thinking skills to exercise mathematical minds.
This resource contains three worksheets:
Evaluating Exponential Expressions
Solving Exponential Equations
Solving Exponential Equations using Logarithms
(there are no natural logs in this exercise)
Each worksheet has a puzzle (easy-difficult). The given numbers form a heart shape, leaving spaces to be completed by the students using the basic rules of sudoku.
Students complete 22, 49, and 55 spaces on the easy, medium, and difficult puzzle respectively.
Why do sudoku in math class?
Sudoku Puzzles improve logic and reasoning, stimulate the mind, encourage decision making, increase concentration, give a sense of accomplishment when a puzzle is solved correctly. . . . and more.
Help your students learn to persevere until the puzzle is solved and have fun!
