Play golf on this virtual course where you have to estimate the angle you want to hit the ball and how far you want to hit it. There are sand traps, water hazards, and trees to avoid. You’ll be getting a good work-out of your skills in estimating length and angles, fractions, decimals, and the use of the virtual ruler and protractor. Your goal, as with any golfer, is to beat par. Unlike the real game of golf, you won’t have to yell “fore” when you hit an errant shot.
