**Socket Sizer**

Schematic Measures the bolt that you need a wrench or socket for. On one side is the metric system and the other side is standard for the U.S. It has a fixed wedge to slide until it's fixed to the bolt. The small window is where you read the measurement. Everyone runs across that bolt that they can't get loose and this simple device will let you know exactly what size wrench or socket you need before you have to get it. This device will Make people more efficient and cut out the frustration of having the right wrench or socket. Then when you realize it's metric, you get even more frustrated you just flip it over. This is a new dimension is measuring! There are fixed tools to measure round object, but this is so much easier to carry with you on a key chain or in I looked under it and seen screw that I needed to take off. I went to the shed and got my universal wrench but the screw was too hard. I sprayed it with lubricant and went to the shed and got a half inch wrench. I went back to the mower and the wrench was too small, it was a five eighths. I was so frustrated; I just stopped for a while and took a break. The next day I called my best friend from the U.S. Navy thirty years ago and said "I wish that radius ruler could measure a bolt." He told me he could do that with the same concept of the radius ruler. He e-mailed it to me that day and I put it together was amazed it works so well, your pocket. Stan Waltz, best friend from the Navy, we did it together and we were partners in everything. He passed Feb. 2011. He told me that his radius ruler patent would cover this concept. After looking closer, I don't think it does. I came up with the idea, he did the parameters and design, and I put it together. Gave myself all rights to do what it I see fit.

## The Next Tool for Measuring

The radius ruler is an innovation so fundamental, it’s only comparable to something like the protractor as a basic measuring device. We want to bring the radius ruler to American students as a learning tool because it’s just as significant as the ruler and protractor in helping them learn the basics of math. It compliments the ruler and protractor by covering that part of the basics they don’t cover.

From Cartesian and Polar coordinates and from math generally, it’s clear that some sense of length, angle, and radius are key to students understanding the basic concepts. Children aren’t born knowing anything about this, and concepts of length, angle, and radius are abstract ideas initially. They don’t have any sense of inches or degrees, let alone the roundness of a corner called radius.

Educators found that children learn best when more of their 5 senses are part of the learning process. They gave students a ruler and protractor, and had them make measurements. The length measurement required taking the ruler in hand, having to concentrate on using eye-hand coordination to line the ruler up with the thing to be measured, and then interpret the graduated scale on the ruler to read the measurement. The hands-on experience from making the length measurements gives them the experience required to develop a sense of length. The same is true with using a protractor for making angle measurements to develop a sense of angle. The significant benefit from this approach is well known.

Although greatly improved, children still struggle with the basic concepts because they still struggle with the concept of radius. Like the 3 legs of a stool, understanding math requires some sense of all three of these basics (length, angle, and radius). Children still struggle because there wasn’t anything comparable to the ruler and protractor for that hands-on experience with radius (until now). This basic innovation means students can now get the significant benefit from using a radius ruler for making radius measurements to develop a sense of radius.

We know from talking to some educators we are right about the benefit of this to students. This is an American innovation that will be manufactured only in America. We want to bring this to American students to give them a leg up in understanding the basics of math. The educational version will be made from thick paper like what we sent you, and this form is accurate enough for teaching purposes, but cheap enough to make sure every student can benefit from it.
