Common Mistakes to Watch For

• Mixing up the order of butterfly stages, especially placing the chrysalis before the caterpillar instead of after. First graders need to remember the sequence: egg, caterpillar, chrysalis, butterfly.
• Thinking every baby animal looks like a small version of its parent. Tadpoles and caterpillars look nothing like frogs or butterflies, which surprises many first graders.
• Assuming all animals start life as eggs. Some first graders forget that mammals like dogs and cats are born live, not hatched from eggs like birds, frogs, and insects.
