Math Mammoth Grade 4-A Worktext is the student book for the first half of grade 4, and part of the Math Mammoth Grade 4 complete curriculum. This book covers addition, subtraction, patterns, graphs, large numbers, multi-digit multiplication, time, and measurement.
The worktext contains both the necessary instruction and the problems & exercises (the 'text' & and the 'work'; thus a "worktext"), and is fairly self-teaching.
The curriculum meets and exceeds the Common Core standards. Please note this is a student worktext and does not contain the answers. The answer key book is available separately.
Features
Our state requires standardized tests each year for homeschoolers and we just received this year's scores for my daughter in the mail. We started using Math Mammoth during the second half of my daughter's 4th grade year and used it for the complete 5th grade year which has just concluded. Even though we used the 4th grade level Light Blue book for her 5th grade year, her Math Total score jumped 36 percentage points from last year to this year! Especially taking into consideration that she was taking a 5th grade level test, I find that level of improvement absolutely remarkable! Thank you so much for such a wonderful product that is so wonderfully easy to use!
Sincerely,
Robin Lindblad
