This week we will continue to look at words within maths. Our focus words for this week are centimetre, and percent.
Let’s look at the morphemes (building blocks) in each word.
When we look at the words centimetre and percentage, you will see that both contain the morpheme cent (hundred). In centimetre there is an I after cent. It is a connective sound to make it easier to say, when joining the two morphemes (units of meaning). Percentage, doesn’t have a connecting sound as the a at the beginning of age, make joining the two morphemes together easy.
Last week we had the word diameter. Meter means measure. This week we have centimetre. Metre is spelled slightly different but still means measure but there is a way of knowing which to use.
Let’s try to extend our knowledge of these morphemes and identify them in other words. How do these morphemes help us to understand each word?
Can you think of other words containing each of these morphemes? I’ve done one in each group for you. https://membean.com/roots will help you find words, if you are stuck.
Write a word sum for each of the words you have created using the prefixes, root words and suffixes. E.g. rad + i + ate + ion = radiation
To use this as a spelling strategy each day of the week, see the weekly plan.
