Pros: A fun setting for kids to practice a foundational math skill.
Cons: Users can't navigate to a main screen after starting, and kids don't get useful hints or feedback.
Bottom Line: A quick, easy-to-use practice tool for comparing numbers through 100, but kids should have prior knowledge since they won't get helpful feedback.
Greater Gator could be a fun way for kids to practice after learning about place value and ordering numbers. Start with the first level, comparing numbers 1 through 10, and have kids complete the game as solo work. As kids learn to compare larger numbers, have them complete more levels. They will have to start from the beginning, since there doesn't seem to be a way to navigate to a menu and start at a particular level. Still, that extra effort isn't all bad: More repetetitions at each level will give kids plenty of useful practice.
In Greater Gator, kids have to slice a rope that holds the greater of two numbers. The number then drops into the water; if the answer is correct, an alligator chomps and swallows the number. If the two numbers are equal, kids tap an equals sign. At the end of each level, there is a "feeding frenzy": Numbered fish swim across the screen, and kids have to tap the fish in order from largest to smallest until all of the fish have been eaten by the alligator. There are four levels of gameplay, and each level has 10 problems. Numbers get larger with each level, ending with numbers through 100.
The app has a clean layout with bright and cheerful graphics. Greater Gator's simple approach to learning makes the game easy for kids to use as a practice tool. Kids will build on their learning of number sense by comparing and ordering numbers up to 100. In one mode, kids focus on comparing two numbers. In another mode (Feeding Frenzy), kids order a set of numbers from largest to smallest. Kids won't get any instructional guidance, but they will likely have some fun while practicing an important, foundational math skill. Overall, this is a fun way for kids to practice comparing numbers, but it's frustrating that users can't navigate from gameplay once they start. Better navigation and feedback features would make these useful games even more valuable.
