Throw on your diving helmet, and head into the depths of the sea! Master the number line, including fractions and decimals, while gathering beautiful pearls. Will you find the elusive black pearl?
• Ideal for elementary and middle school students, grades 3-8.
Developed by mathematics educators, researchers, and game developers at the Learning Games Lab at New Mexico State University. Games developed by the Learning Games Lab undergo a rigorous instructional design process, extensive user testing, and input from learners, teachers, and researchers.
Pearl Diver addresses Common Core standards relevant to the number line and properties of numbers, including:
• Understanding numbers, ways of representing numbers, and number systems.
• Understanding and representing commonly used fractions.
• Understanding fractions as part of unit wholes and as locations on number lines.
• Comparing and ordering fractions, and finding their approximate locations on the number line.

Ratings and Reviews
Great idea - lousy quality
This is a great idea, but execution is badly in need of improvement. The first few seconds on every level are wasted as the screen is blocked by an unnecessary message. That info should be in the tutorial or even learned by error. There are the levels where the target numbers are too small to read (the font is fuzzy in the numerators of fractions.) The knife is about 500 pts. wide with no indication of where it will cut. Once you cut the eel using the ruler, the scoring shows targets that are off when measured by the ruler provided. The worst mistake is on the last couple levels where a target of 11/2 is displayed as 1/2 - there is no way to know whether the first digit was dropped by programming error or if the target really is 1/2. An educational ap should not have such a gross error.
Practice that number line!
This is a fun way for kids learning fractions and the number line to practice what they are learning. It's not a particularly deep game, if you'll pardon the pun, so if you're looking for an intense gaming experience, you're better off looking elsewhere. But if you're looking for a fun math-based diversion, or need to practice your number line and fraction ordering skills, this is just the ticket! Nice graphics, fun gameplay, and good production values.
Learning the Number Line
My 6-year-old enjoys the first few levels of this game and has played it many times. The later levels with fractions and negative numbers are pretty fun too. Definitely can see how it would help kids practice the number line.
