Title: Pick-a-Path (NCTM)
Description: This game includes seven levels of play! Each level emphasizes a different skill. For example, levels one – three emphasize multiplication and division, levels four – six emphasize operations with fractions and decimals, and level seven emphasizes operations with exponents. The goal is to move through the maze on a path that will achieve the target number, either a specific value, the maximum value, or the minimum value. (See the screenshot to the right below for an example.)
Advantages: The level includes seven games. Each game increases in difficulty to allow for more practice. Within each game, students have the opportunity to create a path, adding and deleting pieces of the path until they achieve the goal. Even if students make it to the end of the path and are unsuccessful, they have the opportunity to go back and choose another path in order to achieve the goal. Teachers can also find an extensive teacher’s guide on NCTM’s Illuminations website, accessible through the help button.
Disadvantages: Sometimes the target is the “minimum” value or the “maximum” value. Without knowing specifically what these values are, it can be frustrating to determine the correct paths. However, the challenge of having to think about how to adjust the path to make the result smaller or bigger is good!
