Build words with your Tri-Blocks tub and learn short vowels, long vowels, adjacent consonants, split digraphs, multi-syllabic words, and adding suffixes. Turn each Tri-Block and manipulate the middle sound (CVC or CVVC), change a blend ('sp' to 'sl' or 'st'), or change a spelling (y to i) when adding a suffix. Tri-blocks let you know your spelling rules by their color coding and their unique block orientations. Unique connector block included for building multi-syllabic words.
Contains 90 color-coded blocks and a teaching guide that follows a systematic phonics progression.
