Uppercase and Lowercase Worksheet

Knowing that every letter of the alphabet comes in two forms is one of the first steps a child takes toward reading, and this uppercase and lowercase worksheet gives them focused practice with both. Kindergarten students learn that the capital B at the start of a name and the small b in the middle of a word are the same letter wearing two different coats. Matching those two forms, and then sorting a letter into the uppercase or lowercase family, builds the quick, automatic letter recognition that fluent reading depends on.

This printable uppercase and lowercase worksheet keeps that skill front and center on a single clean page. In Part A, students draw a line from each uppercase letter to its lowercase partner, working with B, E, H, N, and R. The lowercase column is deliberately scrambled, so a child has to look at each letter and think rather than simply match straight across. In Part B, students take four letters from the word bank and write each one on handwriting guides inside the box where it belongs, either Uppercase or Lowercase. Three-line guides give young writers the top line, dashed middle line, and baseline they need to form each letter at the right height. A friendly watercolor rabbit sits beside Part A as a reminder that Rr is for rabbit. Print it, hand it out, and check the work in seconds with the included answer key.

What’s Included

• One printable Kindergarten worksheet covering uppercase and lowercase letters
• Part A: five uppercase letters to match to their scrambled lowercase partners
• Part B: a four-letter word bank to sort into Uppercase and Lowercase boxes
• Three-line handwriting guides for correct letter height and formation
• A complete answer key on the final page

Three Reasons This Helps Kids

• Pairing capital and small letters builds the automatic letter recognition that early reading is built on.
• Sorting letters by form asks a child to explain their thinking, not just copy an answer, which deepens understanding.
• Writing each letter on guides connects what a child recognizes with what a child can produce, so the skill sticks.

Teacher and Parent Ideas

• Use this kindergarten alphabet worksheet as a quick morning warm-up, then repeat it later in the year to measure growth.
• Turn Part A into a partner game: one child names the capital letter out loud while the other finds its lowercase partner.
• Send it home as homework and ask families to hunt for those same letters on cereal boxes, street signs, and mail.
• Pair it with alphabet flash cards in a literacy center so students can sort a full set of letters by hand.
