This is an awful curriculm for beginners who came into kindergarten not knowing letter sounds or blends. I just started in Jan with my 5 year old this curriculm after laying a good foundation of letter sounds and blends in Sept-dec. She still struggles! And most of the seat work is 3 pages front and back...it takes over an hour to do this work with her and she gets so frustrated she can not get it. I would never recommend this highly challenging curriculm to a mother of a 5 year old. I also asked my mom who has been a teacher for 30+ years and she says that this at 1st grade level work or harder.
I'll start of by saying if your child doesn't do good learning alone or is a slow learner this isn't for you. That being said, If your child likes to be independent and catches on quick they will love this colorful Curriculum. It teaches one to theww concepts and then reviews them for a day or two. It's based on the mastery technique. She loves that it makes up silly sentences and finds it fun. I love it because I asked by friend a teacher if shes wear she should be and he said shes ahead by at least a grade:) My only complaint is the writers of the book are somewhat sheltered for example one of the fill in the blanks was @ss but it was meant to be bass when completed. I blacked out that on the page and moved on . There's been maybe three occasion where I was like what were they thinking, but those small glitches aren't worth it for the overall curriculum is awesome.
I used this with my son this year. It started him off reading right away, which I liked. However, some days the lessons are incredibly long. The ones that were 2 front and backs of a sheet were fine, but any time there were 3 pages he would lose interest after two. It's not an incredibly fun curriculum. The readers are really too hard for the kids to read by themselves. They are useful for learning reading comprehension if you read them to your child and ask the questions. But, he was really looking forward to reading books. He learned to read words but the stories in the book were too hard for him to read entirely by himself. I ended up buying something else with simple readers for my daughter for next year, and I am using those readers now with him. He is enjoying those much more. I have cut back the phonics pages I am requiring him to do to simply the new concepts and we have abandoned the review pages. Overall, I think it's a decent curriculum, and some people may really enjoy it. Just know that there are a lot of workbook pages, and the readers are not really readable by a kindergartener.
