With my children in primary and secondary school, I am being asked to dampen my old knowledge of algebra and geometry, and I expect that the frequency of these homework-related issues will increase over the next few years. With some algebraic comparisons and many geometric questions, I can, by using plotting the X and Y axis on graph paper, not only help me remember how to solve an equation but also help me to explain the answer clearly. Gridzzly provides a simple menu to choose which type of grid you want – square, triangle or hexagonal and either edged or dotted – and a pair of sliders for the size of the grid units and how dark or light you want the lines or dots. There is also an option to print blank sheet music. Click on the ruler at the top to switch between inches and millimeters for your unit of measure.
Using a Brother black and white laser printer, my test prints had the right size, but the lines were light gray, no matter where I put the line weight slider. The results will still be more than enough for homework help. I have bookmarked Gridzzly for the next time my persistent mathematical skills are requested.
