What This Standard Means

What Students Need to Do

Students describe how children grow, move, think, and learn language. They explain why some experiences, such as clear visual input, matter most during certain periods of childhood.

What Mastery Looks Like

A student can identify height gain as physical growth, walking as a motor skill, object permanence as cognitive development, and two-word phrases as language development. They can explain why treating a baby's cataract early may protect later vision.

Common Misconceptions

Students may call walking physical growth rather than a motor skill. They may think a critical period means no learning is possible afterward, or that every child reaches milestones at the same age.

How to Assess It

On an exit ticket, have students classify height gain, walking, object permanence, and two-word phrases by development area. Ask why treating a baby's cataract early can matter for later vision.

Lesson moves

Ways to Teach It

  1. Give pairs milestone cards for height gain, walking, object permanence, and two-word phrases to sort into four labeled columns.

  2. Ask students to write two sentences answering: Why might treating a baby's cataract early protect vision better than waiting until age ten?

  3. Play milestone match: read 'buttoning a coat' or 'using two-word phrases,' then have teams show the matching development card.

  4. Give students a pediatric milestone checklist and have them write two questions a caregiver could ask about movement and speech at a checkup.
