Test your mental arithmetic and estimation skills by throwing "arithmeDarts" at target balloons that are attached to a number line. Aim the darts by estimating the coordinates (as whole numbers, decimals or fractions) of the balloons. How many total points can you earn after throwing only 12 darts? Or how quickly can you accumulate 200 points?
Given a randomly chosen coordinate, predict whether a dart aimed at that point will hit a balloon. The randomly chosen coordinate might be expressed as a single number, or the sum, difference, product, or quotient of two numbers. How many correct predictions can you make?
