Common Questions for this 3rd Grade Math Review

Q: Can I edit the Math Problems?
A: No. The math worksheets are fixed PDF images to ensure formatting stays perfect and standards are met. You can only edit the Names (School, Mascot, Suspects) in the story text fields.

Q: Does the video work if I change the mascot name?
A: Yes! The Video Hook is strategically designed to be “mascot neutral.” It sets the scene of a missing mascot without showing a specific costume, so it works perfectly whether you are the “Eagles,” the “Panthers,” or the “Dragons”!
