The lesson

Warm-up — what is missing?

4 min
  1. Put up a sentence with no capital and no stop. Read it aloud.
  2. Ask what is missing. Take answers.

Teach — the two ends of a sentence

9 min
  1. Fix the sentence in red, saying what you are doing.
  2. Do three more, getting faster.
  3. Then put up 'i went to the park.' Ask what is wrong. The capital I is the one they will miss.
  4. Say the rule: the word I is always a capital, wherever it sits.
  5. Read a sentence with no full stop and run it straight into the next one so they hear why it matters.
“The capital says start. The full stop says stop. Without the stop, my voice does not know where to end.”

Guided practice — fix six

9 min
  1. Pairs fix six sentence strips.
  2. Then they read them aloud to each other, pausing at every full stop.

Independent practice

6 min
  1. Students complete the capitals page and the full stops page.
  2. Read each sentence aloud before they start.

Close

2 min
  1. Put up one sentence with both faults. The class calls out both fixes.

What goes wrong, and why

Each of these is a reasoning error rather than carelessness. The fix addresses the reasoning.

Writes 'i' as a lower-case letter mid-sentence.

Why: Every other one-letter word is lower case, and the rule for I is arbitrary.

Fix: Name it as the one word in English that is always a capital. Arbitrary rules need to be labelled as arbitrary, not explained.

Puts capitals on other important-looking words in the middle.

Why: The child has learned that capitals mark something special, and applies it to the special word.

Fix: Reduce the rule to position: the first letter of the sentence, plus names, plus I. Not importance.

Ends every line with a full stop rather than every sentence.

Why: In their writing the line and the sentence usually end together, so the two have become the same thing.

Fix: Show a sentence that wraps onto a second line. Read it aloud without pausing at the wrap.

If they are not there yet

  • Fix one fault at a time — a week of capitals, then a week of stops.
  • Give sentences short enough to fit on one line.

If they finish early

  • Add question marks to questions.
  • Fix a passage with three sentences run together.
  • Find the capitals in a real book and say why each one is there.

Exit ticket

Rewrite this correctly: 'i saw a fox'

What to look for: Capital I, capital at the start, and a full stop. Two of three is common and tells you which to reteach.

Questions about Capital Letters and Full Stops

How long does the Capital Letters and Full Stops lesson take?

30 minutes, split across 5 timed sections: warm-up 4 min, teach 9 min, guided practice 9 min, independent practice 6 min, close 2 min. The minutes are stated per section and add up to the stated length, so the plan can be cut or extended at a section boundary rather than abandoned halfway.

Which standard does Capital Letters and Full Stops teach?

CCSS.ELA-LITERACY.L.K.2 — L.K.2, Language for Kindergarten: “Demonstrate command of the conventions of standard English capitalization, punctuation, and spelling when writing.” In plain terms, start sentences with a capital, end them with a full stop, and spell simple words.

What do I need to teach this lesson?

Sentence strips with the capitals and stops missing, a red pen for the teacher's demonstration and the printable practice sheet linked at the end of this plan. Everything listed is either ordinary classroom equipment or a free printable from this site — there is nothing to buy and nothing to prepare beyond photocopying.

What mistakes should I expect in this lesson?

Three, each a reasoning error rather than carelessness: writes 'i' as a lower-case letter mid-sentence; puts capitals on other important-looking words in the middle and ends every line with a full stop rather than every sentence. The plan gives the thinking behind each one and the teaching move that addresses the thinking rather than the symptom.

How do I know whether the lesson worked?

The exit ticket asks: “Rewrite this correctly: 'i saw a fox'.” Capital I, capital at the start, and a full stop. Two of three is common and tells you which to reteach. That tells you whether the class needs a reteach or a thirty-second conversation before you plan tomorrow.
