An excellent program!! I used it with all three of my children . The program was recommended by my mother who is a teacher, she used this curriculum with my brothers one of which is currently a creative writing major at UCR.
This book has helped my children with their vocabulary. The exercises are challenging but not too difficult. They also teach other subjects while learning their vocabulary. The price was just right for our budget needs this summer. I will definitly come back and get the next grade when we are finished.
