Have your students try this fun pyramid puzzle and discover how to arrange the numbers on the bottom to get the greatest sum on the top :) 
 
Could be even used in a break-out session with teams! 
 
 
Please check out my YouTube Channel "Math Challenge" for the SOLUTION! SCAN that QR Code to take you right to the video! 
 
I would be SUPER DELIGHTED AND HAPPILY EMBARRASSED LOL if you showed my video to your class explaining the solution! 

I would LOVE to know how the problem worked out for your kiddos :) 
Any requests for future problems is greatly appreciated!
THANK YOU SO MUCH!!
