I just discovered Even Steven and Odd Todd by Kathryn Cristaldi to use during math workshop. Even Steven and Odd Todd are cousins and complete opposites. Even Steven is very organized and likes to have equal groups of objects. Odd Todd enjoys odd things and groups of things that can't be shared equally. My students really enjoyed figuring out how the character names connected to the actions each character did within the story. The story begins with Even Steven making 12 pancakes for breakfast so he's have 6 for lunch. His plan had potential until Odd Todd eats 3 pancakes and Even Steven gets mad. Their interactions continue to have some frustrations and funny moments while leading the reader to think about odd and even numbers.
