Simplex Spelling Light improves spelling and reading skills in a fun and interactive way using a unique “reverse phonics” approach in combination with contextually relevant spelling rules. It has the same critically acclaimed design and features as the full versions of Simplex Spelling but comes with its own new high frequency word spelling lists. This Light version has been made available so that customers can evaluate the Simplex Spelling software to decide if they want to purchase a full version of Simplex Spelling Sight Words, CVC Words, Phonics1, Phonics2, or Phonics3. Simplex Spelling Light contains the main features of the full versions, while targeting more than 50 all new high frequency words in the English language. This makes the Light version a beautiful compliment to the full versions of Simplex Spelling. The Light version also includes placement tests in the Phonics1, Phonics2, and Phonics 3 classrooms to help customers determine which app is the best fit. In contrast with many of the current approaches that use flash cards, Simplex Spelling enables the student to build each word. Students gain skills above and beyond the sheer memorization of words, as the informative spelling rule hint feature explains why words are spelled in a particular manner. Simplex Spelling's unique, immediate letter by letter feedback system is designed with clues and hints that will enable every student to spell each word successfully. Simplex Spelling enhances understanding in a variety of students as it appeals to audio, visual and tactile learners. It is great tool to have for kids learning to spell, remedial students, or those learning English as a second language. Recommended for ages 5+.
