After children learn the letters and their sounds, they can learn to build simple words. The first word-building pattern students learn is C-V-C (consonant-vowel-consonant). In C-V-C words, the vowels are always short.
The first sentence of a paragraph is usually the topic sentence, which states the main idea. In most cases, every paragraph also has two or more supporting sentences, followed by a concluding sentence.
The color-coded Reading Rods® system teaches the simple sentence formula: 1 green rod (noun or pronoun) + 1 yellow rod (verb) + end punctuation. All other rods add more information to the simple sentence.
