Hungry Guppy
Hungry Guppy has an awesome Parent Guide that helps you customize the app for your child.  In the Dots levels, young children who don’t yet know number symbols can practice addition. They’ll learn, for example, that ● + ●● makes ●●●.  In the Mixed levels, kids will learn number symbols. For example, ●●● and 3 have the same meaning, even if the dots are in a different alignment or in funny colors.  In the Numbers levels, learners can practice adding numbers up to 5, seeing the many different ways to make a sum.
Hungry Fish
Hungry Fish has a Parent Guide that helps you customize the app for your child.  Most addition games teach in the form 3 + 4 = __; Hungry Fish challenges players to find different ways to make a 7 (1+6, 2+5, 3+2+2, etc.). There are 18 levels of challenge (for 4-year-olds to adults) (but only in the pro-version) and bonuses to customize your fish with new colors and fins.  Some learning goals are: To develop fast, agile mental arithmetic, to learn there are multiple paths to add up to every sum, to build automaticity in adding and subtracting numbers
Find Sums
There are two modes provided to support your child as they play the game. The goal is to choose a pair of numbers that cause all of the un-shaded spaces to be filled with apples.  This mode is appropriate for Kindergarteners and First Graders. The focus should always be on sense-making and accuracy before speed. Ask your child to explain how they know what the other number should be and what strategies they are using. Remember that this game is not intended to replace instruction – but rather to supplement it with an activity to support mastery and fluency.
Tric-Trac
This is a two-player game, so YOU can play with your child. Players take turns rolling two dice, finding their sum, and then matching the sum to one or more numbers in their hand. Every match eliminates that number or numbers from a player’s hand and reduces their score. Players try to eliminate all the numbers in their hand. Play continues until no more sums from the dice can be matched to a number or numbers in a player’s hand. The player with the lowest score wins the game! With Tric-Trac, children practice basic addition facts and number composition.
Top-It Addition
This is another two-player game from Everyday Mathematics, so YOU can play with your child. Players take turns drawing two cards, finding their sums, and then comparing the sums. Players score points for correctly finding their sum, identifying the greater sum, and for having the greater sum. The player with the most points at the end of 8 rounds wins! With Top-It Addition, children practice basic addition facts and number comparisons.  Like it?  Try Top-It Subtraction for $1.99
Deep Sea Duel
Okta challenges you to a duel! That crazy octopus wants to play you in a game where the first person to choose cards with a specified sum wins. For the 9-card game, the first player to choose three cards with the target sum is the winner. In the 9-card game, if you choose 5, 1, 4, 7, and 6, and the target sum is 15, you would win because 5+4+6=15.  For the 16-card game, the first player to choose four cards with the target sum is the winner. Parent supervision is recommended.  This is a great game to help develop math talk with your child.
Math Bingo
There are five different games in Math Bingo: Addition, Subtraction, Multiplication, Division and Mixed.  There are three levels of game play in Math Bingo: easy, medium, and hard. Players will be prompted to select a game type and level before game play. The object of Math Bingo is to get a pattern of five Bingo Bugs in a row by correctly answering math problems. Math problems are presented at the top of the game screen. Feedback is presented at the bottom of the game screen. Bingo Bugs are the reward.  Kids LOVE the Bingo Bugs!
Sums Stackers
Sums Stacker is a "Math Doodles" challenge that provides plenty of addition and subtraction practice, within a recreational math setting. The mathematical puzzle allows children to play with different representations of numbers, while developing their number sense to create strategies to help them solve problems. There are two modes of play, solve and race, and two difficulty levels. This is a great challenge activity for young children.  It is recommended that parents take a tour of the app before passing it on to their child.  It may even be a challenge for some adults :)
