My kids don’t struggle with math, but I haven’t been very good about keeping them on track with their math curriculum. Also, we changed our homeschool math program and in the change-over some concepts ended up getting skipped. I’ve been looking for a good way to get my kids a bit more “caught up” on math and cover the topics they missed. I was very excited to get the opportunity to review the Blue Series individual math units by Math Mammoth. We got Geometry One and Measuring Two for my 11-year-old and Introduction to Fractions for my 7-year-old.
We ended up having my 7-year old work on Introduction to Fractions and my 11-year-old work on Geometry One to start. My husband did most of this math work with them because he has been the most “concerned” about their math abilities.
My husband and I were both incredibly impressed with this program. The concepts are presented in a logical, linear, and progressive way but focus on only one main math concept. Allowing for intensive review, practice, and/or remedial learning (what we used it for) of that concept.
Each book is a simple PDF download that you can print off for each child in your family. The Blue Series is a combination of textbook and workbook. The text contains a table of contents and an introduction that explains the scope of that workbook and how the lessons compare to grade levels. For example, in the Introduction to Fractions text it says that the first lesson is about equivalent to second grade while other lessons cover third and fourth grade level work. Since the text covers only one concept it spans several grade levels.
After the introduction, there is a long list of free online resources that can be used to enhance your study. We have not yet explored these resources but it is an additional feature included in the book which is a nice bonus.
The Introduction to Fractions text covers fraction concepts generally covered in grades 1-4 including mixed numbers, comparing fractions, equivalent fractions, adding and subtracting like fractions and mixed numbers, and multiplying fractions by whole numbers. At the first grade level students generally just cover halves and wholes. At second grade levels they may introduce simple fractions. The bulk of this text covers third and fourth grade level fractions.
My 7-year-old was able to pick up the concepts in Introduction to fractions and complete the problems very well. She made it several lessons into the text, quite surpassing the typical second grade level she should be on. She also seemed to enjoy the lessons and did not at all mind working on this math.
Geometry One covers topics generally taught in grades 4-5 including triangles, quadrilaterals, polygons, area and perimeter, and volume of a rectangular prism. My 11-year-old had not covered geometry at all in her other math curriculum so she struggled a bit. We did the first few lessons and then I printed them off again and she repeated them to further cement the concepts. She seemed to like the curriculum even though she struggled a bit with the concepts (because they were completely new). Based on this experience I would say this isn’t necessarily the best option for teaching the concept initially (unless you are willing to do a lot of teaching yourself) but a great tool for reviewing.
Measuring Two is intended for 4th and 5th grade students and covers calculations with time, temperature, length, weight, and volume as well as conversions between units and systems of measuring. We have not yet used this text but like the others it looks like a very comprehensive and thorough course on this particular math concept. I look forward to going through it with my 11-year-old when we finish Geometry.
I am very impressed with these math texts. I have been looking for something exactly like this. I will be using these and some of their other texts in the future to review and cover topics we have missed. I also think these will help me prepare my kids for upper-level math in jr. high and high school. Each book is very inexpensive and can be used with multiple students.
