There is no one definitive order to teach letter sounds, but some common sequences include:
Start with high-frequency letters. These are letters that appear frequently in English words, such as s, t, r, m, n, a, o, and p. Teaching these letters first will help children start reading simple words more quickly.
Teach letters that make similar sounds together. This will help children learn to distinguish between similar sounds. For example, you could teach the letters s, z, and sh together, or the letters m, n, and ng together.
Teach letters that look similar together. This will help children avoid confusing similar-looking letters, such as b and d, or p and q.
Teach short vowels before long vowels. Short vowels are more common in English words than long vowels, so it makes sense to teach them first.
Teach lower case letters before upper case letters. Lower case letters are more common in English text, so it makes sense to teach them first.
Ultimately, the best order to teach letter sounds will vary depending on the individual child. Some children may learn more easily if letters are taught in a specific order, while others may be able to learn them in any order. It is important to be flexible and adjust the order of instruction as needed.
Here is a specific example of an order that you could use to teach letter sounds:
s, a, t, p
i, n, m, d
g, o, c, k
ck, e, u, r
h, b, f, ff, l, ll, ss
j, v, w, x, y, z
This order starts with high-frequency letters, teaches letters that make similar sounds together, and separates letters that look similar. It also teaches short vowels before long vowels and lower case letters before upper case letters.
It is important to note that this is just one example of an order that you could use. There are many other possible orders that could be effective. The best way to find the right order for your child is to experiment and see what works best for them.
