Have you seen the terrific animation that Charlesbridge Publishing put together showing how regular color, fluorescence, and daylight fluorescence work? For all the words in The Day-Glo Brothers, and all the clever art, Charlesbridge rightly figured that a little something extra was the best way to get those concepts across.

Well, now Charlesbridge and I have come up with another little something extra: The Day-Glo Brothers Activity and Discussion Guide. In its four downloadable pages, you’ll find discussion questions for before and after reading, a bevy of activity ideas, a glossary, and links to other online resources. It’s absolutely free and available now, and I’d love to know what you think of it.
