This is a great presentation to show at the beginning of the year to show students why they need Physical Education class. To live a healthy lifestyle of course! But a visual works better than just telling them that. I have used CDC powerpoint slides to show the obesity epidemic in the US within this powerpoint. There is also a slide on graphing your own BMI. You just need the BMI sheets which are in my store for Free for an easy download. Here: https://www.teacherspayteachers.com/Product/Calculate-BMI-Disease-Risk-2549103
Did i mention it is editable to tailor to your individual class?
Be on the lookout for a worksheet in my store for kids to fill out as you present to keep them engaged!
