So your class(child) knows his/her letters, but what they might not know yet, is to differentiate between vowels and consonants. This is important to know since they will probably hear those terms often throughout their schooling years. These vowel clip strips are great to use as a whole class teaching tool!
First, how to make these strips. It is super easy: just copy the vowels onto a strip of paper and laminate. The order is not so important. You’ll need one per child and a peg too.
Start off with naming the vowel sounds and clipping each one. Then say a word they are familiar with(a spelling word perhaps) and ask which vowel sound do they hear. Without saying anything, learners must then clip the right vowel on their strip and lift up the strip so the teacher can see. This way a teacher can easily pick up which learner needs intervention in terms of auditory segmentation(breaking up a word into its sounds).
Do this with a few familiar words and also unfamiliar words.
One could have their spelling/sight words prepared on flash cards and the children can make turns reading the words to the class to clip the vowel sound. This way you are working on reading and recapping spelling words as well.
