This week we are learning how to add -tion and -sion to a root word.
Have a close look at our word list. If a word ends in ‘de’, 'd', or 'se' we remove the ‘de’, 'd' or 'se' and the suffix -sion is added e.g. collide + -sion = collision. If a word ends in ‘t’ or 'te', we remove the ‘t’ or 'te' and the suffix -tion is added, e.g. correct + -tion = correction.
Look at the words below:
act explode decide invent
Can you identify the /shun/ sound in each word?
action explosion decision invention
Have a go at adding -tion or -sion to the rest of the words in the word list.
