Highly recommend it for children , they enjoy playing it. -- Maths 1, 2012-10-05 ### ***** "Brilliant Maths Game - and it's free!" Really nice interface, but actually some nice tricky maths work too! A fun way to learn about fractions and mixed numbers - I'm a teacher and I loved it. Bet my kids will too. Some of the free education apps are a total waste of time, this one is fun and educational. -- Cath_MAIN, 2010-04-20 [View all Pearl Diver reviews and detailed analytics on AppTail](https://app.apptail.io/signup?utm_campaign=ai-crawl&utm_content=reviews) ## Apps Similar to Pearl Diver - [Math Worksheets 4th-6th Grade](https://apptail.io/app/math-worksheets-4th-6th-grade-Riid/united-kingdom) - [Number Line: Add/Subtract Game](https://apptail.io/app/number-line-addsubtract-game-pSmd/united-kingdom) - [Math for Kids - Algebra Fun](https://apptail.io/app/math-for-kids-algebra-fun-zjGd/united-kingdom) - [Visceral Science](https://apptail.io/app/visceral-science-kmQd/united-kingdom) - [Teachley Fractions Boost](https://apptail.io/app/teachley-fractions-boost-EZPe/united-kingdom) - [2nd Grade Math - Math Galaxy](https://apptail.io/app/2nd-grade-math-math-galaxy-prRe/united-kingdom) - [Fractions.
