Mimi walks down her little street. All the doors are shut. Knock, knock! The red door opens, and there is a cat. The cat shuts the door and comes along. Behind the blue door is a dog, behind the yellow door a duck, and behind the green door, Grandma, with hugs and snacks for everyone.




The new words in this book
Not closed, so you can go in and see inside. It comes up 7 times, and every time a paper door on the page really swings open.
Closed tight, so no one can see inside. It comes up 7 times, and every time a door really swings shut (with a soft thud).
Made for children just starting kindergarten: one sentence at a time, three to six words, and each door gets its own spread where it opens and then shuts, with no page turn in between. Two sentences take turns and only one word changes: “Knock, knock, open the red door!” (then blue, yellow, green) and “The cat shuts the door.” (then the dog, the duck). Every other word is one a four-year-old already knows: colours, door, cat, dog, duck, Grandma.
Questions to ask while you read
Pause after each spread and ask one question. There are no right answers; the point is to get your child talking.
- 1Are the doors open or shut? How many doors can you see?
- 2Knock, knock! Who is behind the red door? What does the cat do next? Can you say “shut”?
- 3Knock on the blue door with me. Who could be inside? Who is walking with Mimi now?
- 4What colour is this door? Who is inside? Can you shut a door like the duck?
- 5Who lives behind the green door?
- 6Tap a door: is it open or shut? Who is inside?
- 7What snack would you like at Grandma’s house?

Tips for parents
- First time: use Read to me and just enjoy the doors opening. The whole book takes about a minute and a half.
- Knock along! Knock twice on the table every time the book says “Knock, knock”.
- Before each door opens, stop and ask “Who is inside?” Let your child guess, then open it.
- Play it for real: open and shut a door (or a box lid) at home and say the word each time: “Open! Shut!”
