Chant "Bippity, bippity, bumble bee, tell me what your name should be". 

Point to a student and the child says his name out loud.

As a class then repeat his name doing the following:
"clap it" (children say the name and clap the syllables)
"whisper it" (children whisper the name in the syllables)
"silent!" (children say the name with their fingers on their chins)

Phoneme segmentation is essential in developing reading and writing skills. The following activity is an example of how to teach Phoneme segmentation. 

 

Teacher: Show the students a series of 4 images side by side

(up, mum, pot, bat)

 Say the ‘m’ sound to the students. Discuss each of the images, and then allow the students to segment the ‘m’ sound and select which image begins with the target sound.

Being able to delete or add sounds in words is an important skill to develop as it helps students test alternatives for reading and spelling. Many students who have problems with hearing sounds in words will struggle to be able to do this at first. For instance, get students to say a word without the first sound. Again, you can start with your simple CVC words. For example, say ‘mat’ without the ‘m’. Say ‘Tom’ without the ‘t’.

2. Sound substitution
Ask students to change ‘mat’ into ‘sat’ or ‘spend’ into ‘spent’. Change ‘spent’ into ‘pent’. Before they go ahead and make the new word you may like to discuss which sound they are changing. Is it the first, second or third sound? When doing this activity it’s important to only change one sound at a time. The words don’t always have to be real words either. This is really fun to do with made up words. For example, change ‘block’ into ‘blon.’ This helps students really listen to the sounds in the words. For example: mat – sat – sit – sip.

3. Silly sound games

This is a fun activity to do with younger children. First pick a category to focus on, such as animals, names or colours. Pick one thing from the category, such as the colour black. Then ask your students to change the first sound in black to make new silly words. It could go something like: black, glack, slack, clack, plack…. This is a simple activity that can be done while your students are sitting in a circle on the mat.

4. Change the sound

Start by writing on the board a word, such as tram. Then circle or underline one of the sounds in that word.

Select a student to change that sound to a new one to make a new word, then write that word down.

Again in the new word circle/underline one of the sounds that is to be changed.
