STACK UP! For a Cause

Many organizers choose to combine STACK UP! with a good cause that will benefit their school communities.

Though we believe sport stacking and fitness are reason enough to celebrate, we applaud schools that take it a little farther to make a positive difference. Stocking up food pantries, donating coats, hats, socks and school supplies, collecting pennies for research or disaster relief, involving families, inviting community members to take part - we thank you for warming so many hearts right before the holidays!
