8. Curious Creatures – Under the Sea

The oceans are full of curious-looking creatures – if you’re looking for unusual book week costume inspiration you’re bound to find it there!

I remember making an under-the-sea themed costume for my son in prep. It was a costume that my son could easily take off and put on so that it wouldn’t get in the way of playing and eating, and it was so simple to make. My son went as a jellyfish! Here’s what I did: I bought an old grey sheet from a charity shop and cut off a large section to wrap over my wide-brimmed sun hat, padding the gap between the sheet and brim with newspaper to give it that nice blobby jellyfish shape. I cut the rest of the sheet into long thin strips of unequal length and secured them to the underside of the brim with safety pins (it was last-minute – I didn’t have time to sew!). Wearing his boardies and rashie underneath he was totally sunsafe with a unique no-fuss DIY book week costume!

Dragons are always popular in children’s books, especially once children are reading for themselves in upper primary.

With the Pokemon Go app and the recent movie Detective Pikachu, Pokemon are enjoying a huge revival at the moment. The Pokemon Adventures book series is suitable for ages 7-10 and read from right to left in the Japanese style.

She wore them over a yellow t-shirt and trousers, with face-paint rosy cheeks to complete her look.

Tips for Reading With Children:

  1. Talk with your child about the book they are reading. What is it about? Do they like it? What do they think will happen next?
  2. Ensure your child can read and understand the vocabulary used in the books and that they are comprehending what they are reading. Reading should have meaning!
  3. Talk about the pictures, particularly with younger and less able readers. Pictures help children to understand the words.
  4. Ask your child to read some of the words from the book in isolation to ensure they are not memorising the sequence of the text.
  5. As your child gets older or a more able reader, discuss the characters and the words and phrases used by the author.
  6. When your child does not know a word, encourage them to make a sensible guess but do not let them struggle.
  7. Encourage your child to sound out and word build phonetic words, by using letter sounds not letter names, e.g. ‘a’ as in pat. Help them to break down the longer words, e.g. im-por-tant. It is important that your child recognises all the letters of the alphabet and the sounds they make.
  8. If your child misreads a word, stop him or her and say the correct word – although if it is a word which makes no difference to the meaning (for example, ‘home’ instead of ‘house’) it is best to ignore it.
  9. Try to develop your child’s expression and prediction skills, especially when they have become a fluent reader – draw their attention to punctuation, e.g. stopping at full stops and the use of expression when characters are speaking.
  10. Use lots of praise and encouragement and avoid criticism. It is important your child becomes confident with their reading.

Your child may experience a mixture of reading activities in school

  • They should be given opportunities to read individually from reading scheme books.
  • During shared/quiet reading sessions they may be encouraged to read silently or share with a partner a book of their choice.
  • They may take part in group play and poetry reading sessions.


Finally and most importantly, so you can enjoy hearing your child read, make the reading sessions short. Give lots of praise – for effort as well as achievement. If you are anxious try not to let it show. Discuss any concerns you have about your child’s reading with their class teacher.
