Most people know the story of the Cat in the Hat. It's one of my student's favourites. Reading a book can be a great way to begin an activity in class. Books are also extremely useful when you are relieving in a classroom. You can easily turn the day into a 'theme' day where all the activities you do are based around a book. Below are some ideas of how to enjoy The Cat in the Hat that little bit more. 

1. Students can make their own hats.

2. Play a game of Fish, Fish, Cat (Duck, Duck, Goose)

3. Discuss rainy day activities. Ask students to draw/paint what they enjoy doing on a rainy day.

4. Make fish kites 

5. Make a paper plate cat.

6. Make these gorgeous Cat in the Hat posters.

7. Write a summary/book review like the ones found on Art Smarts 4 Kids.

8. Try these free colouring pages from Early Moments

9. Have a magnetic fishing game already made. You'll need cardboard (possibly laminated) with paper clips or safety pins attached. You'll need some 'fishing rods' with magnets. You may want to cut out a fish bowl to place the fish on.

10. Make a kite like the one that Thing 1 and Thing 2 have in the story or get students to design their own. Go outside and fly them before hometime.

11. Ask students to draw themselves on a ball balancing several things at once. 

12. Have some things for students to try balancing e.g. balls, small bean bags, a plastic cup etc. Allow them to hold things and let them try placing these things on their head or feet.
