How do modal verbs change the degree of possibility or certainty in a sentence?

This week in Year 5 we have been preparing all the necessary grammar and writing practise for writing a letter in the past tense - we will be writing in character as Grace in the Titanic story we have been reading. The specific focus for our writing have been: expanded noun phrases, modal verbs and using visual imagery to show characters emotions, rather than just telling how they are feeling using adjectives. In Maths, we have been revising square and cube numbers and have no moved on to multiplying and dividing whole numbers by 10, 100 and 1000. In Computing, we have started curating our website content which we are all making as a class in our Year 5 classes. These websites will all be about cyber safety, and will be published at the end of Autumn 2 for younger year groups to use. In Science, we looked at reversible and irreversible changes and how these occur - we will be seeing some of these reaction live on Monday!
