Here are 5 free math apps for your Nook HD + and Nook HD that students in your classroom could use to help them with them with their Math skills:
Math Racer Addition is a fun math game for kids that requires the player to add different numbers. At the beginning, the player gets to choose the color race car they want and choose the numbers that want to play with (1's, 2's, 3's, 4's, etc). If the player chooses to play with 1's, the game will ask the player to do addition with 1's - i.e. 1+2, 1+3, 1+10, etc. Each time the player gets the answer right, their race car advances to the "finish line". It will track their score and time so that the player can keep track and try to beat their record.
Math Brain Trainer offers levels of difficulty in levels of addition (Easy, Medium, Hard). Each level gives you a time clock which you must beat by selecting two numbers that add to the given target for that level. For example, the target number is 16, thus you could select two eights in order to move on to the next target. It also includes classical music that you can turn on or off that runs in the background while you play the game.
Monkey Math - Jetpack Adventure is a fun game for kids to practice their math skills. You control the main character of the game (which is a monkey on a jetpack) as he races across the "Enchanted Islands of Arithmetics" to stop the evil rogue, "Mean Monkey" from stealing ancient treasures of the island. The game is a side-scrolling adventure where you must count numbers in order to make it to the end of the level.
Mult Mania is another side-scrolling game which you must control the character and answer multiplication questions in order to reach the end of the level. This free version contains multiplication tables for 10X, 5X, 2X, 4X and 9X. According to the notes for the game, this game was created by a veteran middle school teacher.
Kinder Zoo is a game that lets kids build on their math, counting and spelling skills. Students will follow the in-game directions (verbal or on-screen) as they guide the zoo keeper to the right answer. For example, in the "number identification" game the in-game prompter will tell the player to identify, for example, the number "3". The player will then draw a path for the zoo keeper to the animal that has the number "3" on it.
