Hi Christina,
Regarding bonding, I have an activity called "Bond with a Classmate", I made ions of different charges, laminated with yarn, and students wear them around their necks and pair up with other "ion" classmates and fill out a sheet with the compound, names, etc... It seems to work well, gets students up and moving around, and reinforcing concepts about zeroing out the charge etc. 
For polar and nonpolar covalent bonds, I like these sites:

Good luck!
