Sort and match capital letters with their lowercase partners, noticing which pairs look alike and which look different.
Every letter has two forms: a capital (big) letter and a lowercase (small) letter. A and a are partners. So are B and b.
Some partners look almost the same, just a different size, like C and c. Other partners look totally different, like B and b.
Mastery looks like: They can match at least ten capital letters to their correct lowercase partner and explain which pairs look alike.
Common stumbles: Matching letters by sound instead of shape; assuming every pair looks alike; mixing up b and d while sorting.
