Hello, this year I have started using fix it grammar and IEW Student Writing with my 4th, 5th, and 6th grader. This is how I taught it…the first half of the year I had my 5th and 6th grader do 2senteces a day because I believed the first fix it book (The Tree Nose) was “too easy” for my older ones to just do a sentence a day. So by them doing 2 sentences a day they will have completed the first and second book of fix it grammar in one year. My 4th grader however, only does one sentence a day and is doing great with it. So everyday my kids are doing 1 to 2 sentences a day Monday-Thursday in their fix it grammar. Writing they do everyday also! There is a scope and sequence in the front of the book that I follow. If you just did the lessons that follow the DVD it will only be a 15week curriculum, but if you do the reinforcement lessons (like I do) then it will be a full year’s curriculum. I would say follow the scope and sequence to make it easy on yourself. so to summarize yes, my kids do fix grammar and writing everyday! I hope this has helped you a little.
