Teacher's field guide

What Students Need to Do: Students put insect life stages in order and describe how the young insect changes. They tell whether the insect passes through a pupa stage or grows through a series of molts.
What Mastery Looks Like: A student can identify a butterfly’s caterpillar and pupa, then explain why its young looks unlike the adult. They can identify a grasshopper nymph and explain that it grows by molting without becoming a pupa.
Common Misconceptions: Students may think every insect has a pupa stage. They may also call a grasshopper nymph a larva or mistake each molt for a new life stage.
How to Assess It: Exit ticket: A beetle goes from egg to grub to pupa to adult. A cricket goes from egg to small, wingless cricket to adult. Name each pattern and explain the clue you used.

Lesson moves

Give pairs paper cutouts of butterfly and grasshopper stages to arrange, label, and connect with arrows.
Ask students to write why a grasshopper nymph resembles its parent but a caterpillar does not resemble a butterfly.
Play a two-pile card sort with stage pictures of beetles, moths, crickets, and dragonflies, then have students defend each placement.
Show a mosquito life-cycle diagram and ask which stage removing standing water would interrupt.
