3. Teach frequent, highly regular sound-spelling relationships systematically. [Back]
Only a few sound-spelling
relationships are necessary to read. The most effective instructional
programs teach children to read successfully with only 40 to 50 sound-spelling
relationships. (Writing can require a few more, about 70 sound-spelling
relationships.) The chart below is not taken from any particular program
but represents the 48 most regular letter-phoneme relationships. (The
given sounds for each of the letters and letter groups are either the
most frequent sound or occur at least 75% of the time.)

To teach systematically
means to coordinate the introduction of the sound-spellings with the material
the children are asked to read. The words and stories the children read
are composed of only the sound-spelling relationships the children have
learned, so all the children must be taught using the same sequence. The
order of the introduction of sound-spelling relationships should be planned
to allow reading material composed of meaningful words and stories as
soon as possible. For example, if the first three sound-spelling relationships
the children learn are a, b, c, the only real word the children could
read would be cab. However, if the first three sound-spelling
relationships were m, a , s, the children could read am, Sam, mass,
ma'am.
