Other Reading Challenges
The reading your kids do for Bookroo also qualifies for these other summer programs. Download each form to track your reading and claim the reward.
These are external programs run by other companies, not Bookroo. We're just showing them as a convenience — programs and rules can change at any time, so check each company's official page for current details.
Set your reader up with a free Bookroo account. Track your reading. Watch the rewards roll in.
