I’m currently completing a maths course with the Open Polytechnic to further enhance the learning experiences of students. Currently, I’m working on a Geometry and Measurement paper and came across a great little online program called The Eyeballing Game. It tests how good your eyes are, would be quite useful for builders and engineers. Why not try it out and see what score you can get. My best score after a few goes was 5.1. The lower your score the better.
