Do what is motivating, productive, and efficient in phonics & spelling "instruction" instead of what can kill interest and focus. Use Phonics & Spelling Puzzles, Advanced Level in place of traditional exercises! So much for learners as they: interpret visuals, figure out spellings from cues and clues, discover patterns, get "ah-hah moments" that act as memory pegs, and experience satisfaction when it all "comes out even." Compare that to "tedious practice" and boring white space. There are 3 other "levels" of Puzzle-Solving Presentations, Practice, Reinforcement, & Challenge: Basic (978-1-934637-42-5), Beginning (978-1-934637-43-2), and Intermediate (978-1-934637-44-9). In the first two, Alphabet Sections review the differences between letters and sounds, ensuring phonemic awareness. Initial & Final Consonants + Vowel Sounds & Spellings are covered in all Levels. Three levels provide 12 different puzzle formats targeting Syllables ("Closed Vs. "Open", Stress Patterns, Syllabification); two have Word Parts (Roots, Affixes, Compounds); and one has Word Groupings (Confusing Items, Homographs & Homophones, Synonyms).
Funny thing: learning that occurs during pleasurable situations that involve "doing" is more likely to promote successful skills acquisition and retention than forced study associated with anxiety.
