The Master Angle

The Master Angle

I was thrilled when Master Innovations, Inc. sent me a copy of their Master Angle and the Mastering the World of Angles workbook. As a member of the TOS Crew, I was given their program to use with my children in exchange for my honest review of the Master Angle. My first impression was, "Wow! A geometry curriculum made for students in grades 1-4. " The full-circle protractor looked very different from the typical half circle protractor that most high school student use. I decided to use the Master Angle with my 9 year old daughter, Karina.

The 76 page consumable workbook is printed in black and white with an easy to read font. The graphics are clear and the text was easy for my daughter to understand. I was impressed with the content of the program. It was not watered down and the master angle was very easy for my daughter to use. She was not only able to measure angles accurately, but she also understood the concepts that were introduced.The course begins with a basic introduction to lines, rays and angles. These concepts are then reinforced with hands on activities. Karina was quickly able to distinguish between acute, obtuse and right angles. She also learned how to construct angles using the Master Angle. Next, reflex and straight angles were presented, followed by learning about complementary , supplementary, adjacent and vertical angles. These are concepts that many students do not master until high school. Many of the definitions were learned through discover, rather then memorization. Now that is how I want my children to learn.

Overall, I loved this program! Karina enjoyed using the protractor and gained a great foundation for her future math studies. I wish I used this with my older children , prior to their upper level math studies. My only complaint is that the company doesn't make a workbook for upper level students. Although, I'm sure it could be modified easily to use with older students.

The Master Angle can be purchased at for $5.95 and the workbook is available for $15.95.
