Description
A no print, no-prep resource to give your students practice filling in the simple interest formula of I=PRT, solving for missing values, and interpreting the answers! This product includes 20 fun and functional slides that give students a scenario around interest, time, interest rate, and principal balances. Students will type the known parts of the equation into the text boxes provided and represent the unknown value with an X. Students solve the equation, and record their final answer. It's a simple and straightforward practice activity to utilize in your classroom! This deck has alt-text and z-order accessibility. While recording values in the equation, all rates must be written as decimals, time may be written as a whole number to represent years or as a decimal (i.e. 0.5) or fraction (9/12) to represent months. Number values may or may not include a comma. While recording final answers, monetary values must include a dollar sign ($) in front, and may or many not include a comma. Interest rates must include a percent sign (%), and time must include a label (i.e. years or months), to assist with clarity.
