MATH Monday: The Rule of 72
This week on NGPF's Math Monday, we'll use function notation while simultaneously applying the Rule of 72! Brush up your own math skills or use these resources with your students to teach them the math behind how Federal tax brackets work.
- View the MATH Collection: First up, students can see a model of how to use function notation to solve a problem involving the Rule of 72. Check it out in MATH: Rule(72)
- Formula of the Day: Once students have been introduced to the Rule of 72 and they have an understanding that it is used to approximate the number of years it will take to double a fixed amount of money that is growing at a fixed interest rate or rate of return, then they can move on to using the function notation shown below when solving problems involving the Rule of 72.
3. Watch the EdPuzzle Video: Your students can also watch this EdPuzzle video for an interactive introduction or review of the Rule of 72!
4. For Your Learning: Join Yanely and Abby for Virtual PD today as they review activities like this one, and dive into how to use the new MATH Collection while teaching remotely!
