Product Description
This is a bingo game with 16 different bingo cards that can be printed out and handed out to students for them to practice calculating the three different wave properties of frequency, wavelength, and speed. This should not be used as a stand alone item as the students should first have a grasp of what these properties are, how they are related to each other, and how they affect the behavior of waves. This also should be used after the students have had some practice with doing these calculations on their own or in teams as it will be difficult for them to do these calculations on the fly as you call out problems that are included on the answer sheet if they have not had that practice.

I use the algebra circle or triangle method to teach them how to know what the equation is for each of the wave properties. They can also input the values directly into the circle or triangle so they know which values they are multiplying or dividing. It should also be an emphasis to show them where the unit values come in the answer when making these calculations.

To use the answer sheet, pick rows randomly from the lists and call out the two values with their units that are NOT bolded (the units are important so students can determine which variables they are given and what they will have to calculate for) but DO NOT call out the bolded value as it is the answer. As you call out a row of values be sure to mark it somehow so you know which you have called and which you have not. This is also helpful for when a student gets a BINGO to check their answers. I always have the kids call out their values after I have checked their card to ensure the values are covered in the correct sequence on the card. If they give a value that was not correct (likely because they did a calculation incorrectly) I have them remove the cover on that value and continue the game. I'll often keep calling until there are several BINGO's and then have the kids reset their cards to play again.
