There is no rule this week for spellings.
Instead I would like you to take a look at the year 3 spelling list below and find 10 words that you would like to practice.
You can write them in your neatest handwriting and use the look, say, cover, write and check technique.
Then you can write them into sentences after using a dictionary or the internet to look at the meanings.
On Friday, ask someone to test you on the words that you chose.
