Teachers can use the game as a post-lesson practice tool or as a reward for kids who finish classwork early. If kids are playing for the first time, have them play through the animated tutorial in pairs. Then help kids set up a profile name and choose a game level based on what they are learning in the classroom. Kids can play alone or with classmates. Extend the learning experience by having a brief class discussion about the game and how it helped kids.Continue reading Show less
Numbers League is a math practice app that revolves around an exciting superhero mission. Villains (creatures, not humans) are roaming the town, and number heroes must capture them by matching combinations of numbers to each villain's Kryptonite-like digit that renders the villain powerless. The baddies land in jail in this completely nonviolent superhero vs. bad guys game. In the optional practice round tutorial, kids create their personal hero and begin to understand how the game works. Another tutorial option simply explains the game in text and images. The practice round is highly recommended, especially for kids at the younger age recommended for this app. Kids can play solo or take turns with some of their classmates, each of whom (up to four) can have their own superhero avatar.
Kids make a hero by combining superhero head, body, and feet sections, where each part has a certain numerical value. A full compiled hero's value is the sum of its body parts, and they'll attack villains with the same number. Different strategies throughout the process can be used to attain the villain's target number, such as adding multiple heroes' sums. There are also "simple devices" that can be attached to the heroes to give them extra mathematical abilities.
Playing the game, younger kids practice basic arithmetic and mental math. Older kids can play a more challenging game that includes negative numbers and multiplication, depending on which level is chosen (1-5). Once kids understand the game, Numbers League is so much fun that kids revel in practicing math to rid the city of its villain problem. As a result, they're learning an even bigger math lesson: that using numbers can solve real-life problems (even though in this game the "real life" problems involve masked superheroes and silly bad guys).
Each round begins with a newspaper showing the player's name in its headlines with a motivational caption. Players tap on that headline to start, and create heroes to defeat villains. The levels progress in difficulty so that by the last level, players are using sophisticated math skills to defeat the baddies. Kids must use logic to figure out which new heroes to build, because they can only carry seven heroes at a time within the game. When kids have captured all the villains, the game is over. This sounds a lot more complicated than it actually is; however, it's crucial that kids read the traditional tutorial or play the interactive tutorial (recommended method) before playing the game the first time. There are also many explanation tabs throughout the game and hints if a kid gets stuck. However, the hints could be a bit more instructive so kids can be sure to learn from their errors. The ability to track progress would be beneficial as well.

Operations And Algebraic Thinking
Add and subtract within 20, demonstrating fluency for addition and subtraction within 10. Use strategies such as counting on; making ten (e.g., 8 + 6 = 8 + 2 + 4 = 10 + 4 = 14); decomposing a number leading to a ten (e.g., 13 – 4 = 13 – 3 – 1 = 10 – 1 = 9); using the relationship between addition and subtraction (e.g., knowing that 8 + 4 = 12, one knows 12 – 8 = 4); and creating equivalent but easier or known sums (e.g., adding 6 + 7 by creating the known equivalent 6 + 6 + 1 = 12 + 1 = 13).
Apply properties of operations as strategies to add and subtract.3 Examples: If 8 + 3 = 11 is known, then 3 + 8 = 11 is also known. (Commutative property of addition.) To add 2 + 6 + 4, the second two numbers can be added to make a ten, so 2 + 6 + 4 = 2 + 10 = 12. (Associative property of addition.)
Determine the unknown whole number in an addition or subtraction equation relating three whole numbers. For example, determine the unknown number that makes the equation true in each of the equations 8 + ? = 11, 5 = _ – 3, 6 + 6 = _.
Fluently add and subtract within 20 using mental strategies.2 By end of Grade 2, know from memory all sums of two one-digit numbers.
Interpret products of whole numbers, e.g., interpret 5 × 7 as the total number of objects in 5 groups of 7 objects each. For example, describe a context in which a total number of objects can be expressed as 5 × 7.
Interpret a multiplication equation as a comparison, e.g., interpret 35 = 5 × 7 as a statement that 35 is 5 times as many as 7 and 7 times as many as 5. Represent verbal statements of multiplicative comparisons as multiplication equations.
