Phonics Blox are the new color-coded blox for teaching word building and decoding. Each cube can be grouped by color. This set includes the following blox: 10 short vowels; 18 consonants; 6 magic Es; 10 consonant digraphs; 4 vowel digraphs; 4 changeable vowels; 6 r-controlled sounds. Phonics Blox can be twisted to support the development of phonemic awareness and visually show substituting a new letter to spell a new word.
