Rules Rule Level 4 is the fourth book in a series of graded books which systematically introduce 40 spelling rules. 10 new spelling rules are introduced in each book and previously introduced spelling rules are revised and covered at a higher level of complexity. Book 4 is designed for learners who have a reasonable reading and spelling skills, but want to take this knowledge to the next level. There are five different activities associated with each spelling rule. Each activity is designed to help develop students’ understanding of the spelling rule and the ability to apply that knowledge in different situations. It is an effective resource for students with dyslexia or having spelling difficulties or students who just want to improve their spelling.
