Fun and effective- My niece is proof!

A couple years ago, my husband and I played this app on vacation with our niece. The other day, we got this email from her (she’s now 11 years old).
Hi guys,
remember Stack the States? I have to say something about it, THANK YOU FOR SHOWING IT TO ME!!! Thanks to the game, Im now #2 in Social Studies of 5th grade! Because I know all the states, Im doing capitals only with one other classmate! Yay!

Hugs and kisses,
