Estimating is an essential skill. We estimate all the time, even when we dont realize it. Just like every other skill, the more we practice, the better we get.
Guesstimates is a fun way to improve your estimating skills. You are asked twelve questions to which you almost certainly dont know the answer. But you can make educated guesses and employ other techniques like process of elimination.
Guesstimates keeps you engaged by providing medals for number of correct scores, high scores, and number of games played. See if you can get a gold medal in each category. Start with easier questions, then challenge yourself with harder questions for more points. When you think youve mastered it, switch to metric and strengthen your understanding of grams, meters, and liters. And remember, the more you play, the better you get!
