Here are some more advanced reading lessons.  I usually go onto these
exercises when children have mastered the phonic sounds for reading  and are
ready for this next step.

We are going to put together 4 different types of materials for your
child to choose from to learn about phonograms and digraphs.
A digraph is a combination of 2 letters that make a single sound.

Phonogram Boxes 
This is a collection of cards with pictures and corresponding words of
certain word groups. Each box has either a phonogram or digraph of the
most common language words. You can find more words here .

Use note cards for the words and on another set of cards to provide
matching pictures that match the words.-
For example, one group can be ai words such as-
mail
pail
nail
rain
train
tail
rail
Put the cards in a box with ai written on the front,outside part of the box.

The next box can be ea words such as-
pea
seat
tea
leaf

Put the cards in a box with ea written on the front, outside part of the box.

The child reads the words and matches it to the picture.
If this is difficult, use a word card with the picture on the left
corner as a guide.

Continue to make other boxes as your child progresses.

Booklets
The next material can be made with small, different colored notebooks,
such as assignment notebooks. Write the phongram or digraph on the
outside of the notebook. On each page write only one word.
For example, write oa on a notebook. On each page write only one word.                on the first page write the word-
soap
on the second page the word-
coat
on the third page the word-
goat
on the forth page the word-
toad
on the fifth page the word-
loaf
Make several notebooks with different word groups.
Let your child read the books. This exercise is more difficult because you don't use pictures as reading clues.

Word Lists
The third material is the digraph or phongram word list-
On sheets of paper or use a word processor to write out the word group
lists-ea in each word is written in a different color.
For example

ea
pea
meat
seat
bean
team

Your child reads the lists.

Envelopes
The fourth material consists of a large packet of smaller packets of
word groups of phonograms or diagraphs which are alike in sound such
as- ea, ee, ie, and y.
These small packets are usually envelopes with the sound is written on
the outside. All these small packets or envelopes are put in a large
envelop with all the letters written on the outside (ea ee ie y).

For example, in the ea envelope are cards with one word written on them
such as
pea
meat
seat
bead
bean

In the ee envelope are cards with one word written on them such as-
bee
tree
reel
eel
feet

In the ie envelope are words such as-
field
yield
priest
fiend
pier

In the y envelope are  phonograms  (y has an "e" sound)  such as-
candy
dolly
holly
very
bunny

Again, your child reads the words in the packets.

Extensions

Provide two, small moveable alphabets for your child to build the words.
Use two different colors. One color for the phogram or diagraph
letters and the other color for the other letters.

Provide different colored pencils and small notebooks so the children
can write the words.

Children can work with any of these 4 exercises. I try to overlap with
the same words for all four exercises. This a great way to teach these
more difficult words without your child losing interest. Children like finding their own
new words and adding to the phonogram word lists.
