The Lil’ Reading Scientists TM Word Building Boards # 3 and 4 are perfect for word building exercises for students working on Levels 7-13 in the LRS curriculum. Our unique color coded system of letters and letter clusters helps students to learn the difference between blends, chunks, digraphs, vowel teams, bossy R, suffixes, and prefixes. Students easily learn the color coded system, and can then build words phonetically, add prefixes and suffixes, and recognize their errors readily. Use the Boards # 3 and 4 with our Word Building/Spelling Kits, Levels 7-16 (digital downloads). Also use our Color Coded Sound Blocks with these Kits, to enhance the word building process, and to deepen students’ knowledge of phonology.
