I was relieved to find a English supplement that both of my children actually enjoy doing. We love the online features connected with the book including interactive games. This book could work nicely for homeschooling, extra tutoring, or summer supplement.
I purchased Wordly Wise for both my boys, grades 4 and 9. The vocabulary words are great. Each night on a board I have written 5 of each boys words. We work them into sentences and talk about the meanings and different uses. Since there are 5 lessons for each group, by the end they have real knowledge of the meaning and spelling.
We purchased this based on the sample, but it has so surpassed our expectations. My son has great language skills, and Worldy Wise has a great balance of exercises that are both right at his level and somewhat challenging. (We also use the words for charades for extra comprehension). Each exercise is brief enough so that it is not frustrating, but "meaty" enough to convey the skill. I also like that they place the word list on each set of pages for the child to refer to if needed. The vocabulary selections are wonderful, and it is organized well. I would recommend this for children at any skill level.
