Remember
- Use capitals and clear sentence endings.
- Commas organise meaning; they do not mark every breath.
- Possession: pupil’s, pupils’, children’s. It’s expands to it is or it has; its does not.
Punctuation that makes meaning clear
Hi, I am Bea! Mark sentence boundaries, use commas clearly and distinguish plurals, possession and contractions. Foundation to core; Years 3–5.
Short lesson
Begin sentences and proper names with capitals. Use a full stop to end a statement, a question mark for a direct question and an exclamation mark when the meaning warrants it. Read the sentence's structure rather than putting punctuation wherever you happen to breathe.
Use commas between items in a list and after fronted adverbials in this practice: “Before sunrise, the boats left.” A comma can prevent confusion: “Let's eat, Sam” addresses Sam. It does not mean Sam is the meal. Avoid separating a simple subject from its verb: “The children, waited” is incorrect.
An apostrophe can mark missing letters: do not → don't. It can also mark possession: one pupil's coat; several pupils' coats. Irregular plurals that do not end in s take 's: children's books. A normal plural does not need an apostrophe: three coats.
Its is possessive; it's means it is or it has. Expand the words to test which you need. Possessive pronouns such as yours and theirs also have no apostrophe.
Worked example
“The dogs collar was red.” If this is one dog, write “The dog's collar was red.” If several dogs each have a collar: “The dogs' collars were red.” We changed the noun and verb as well as the apostrophe because the meaning changed. Never guess the number of owners if the context does not tell you.
Common mistakes
Do not use apostrophes simply because a word ends in s. Do not turn every pause into a comma or use a comma as a substitute for every full stop. A final comma before and in some lists is a style choice; clarity matters.
Try it
Have a go on paper or say your answer aloud, then open the answer.
Foundation
Add capitals and end punctuation: “on saturday maya visited york”
Show answer 1
“On Saturday Maya visited York.” Capitalise the opening word, day and proper names; finish the statement with a full stop. “On Saturday, Maya visited York.” is also accepted, with a comma after the fronted time phrase.
Core
Add a comma to show that a child is speaking to their grandmother: “Let's paint Grandma.” Explain how the comma changes the reading.
Show answer 2
“Let's paint, Grandma.” The comma marks direct address: Grandma is being invited to paint. Without it, the sentence can mean painting Grandma. The apostrophe already marks the missing letter in let us.
Core
Add the missing apostrophe for the stated meaning: A. “the teachers desk” (one teacher); B. “the teachers desks” (several teachers); C. “the childrens coats”.
Show answer 3
A: the teacher's desk. B: the teachers' desks. C: the children's coats. Singular teacher takes 's; a plural already ending in s takes a following apostrophe; the irregular plural children takes 's.
Core
Choose its or it's: “___ a windy day, and the tree has lost some of ___ leaves.” Give the expansion that proves your first choice.
Show answer 4
“It's a windy day, and the tree has lost some of its leaves.” The first expands to It is; the second expresses possession and cannot expand to it is or it has.
Stretch
Correct the punctuation: “After the match the players, packed their boots shirts and gloves.” Explain both the comma you add and the comma you remove.
Show answer 5
“After the match, the players packed their boots, shirts and gloves.” Add a comma after the fronted phrase and between the first two list items. Remove the comma separating the subject the players from its verb packed. Accept an additional serial comma after shirts as a style choice.

Bea’s tip: For each apostrophe, ask: missing letters or possession? A normal plural needs neither.
Check yourself
For an apostrophe, ask: missing letters or possession? If neither applies, check whether it belongs at all.
