Get 11 is a number puzzle game where players combine matching numbers on a grid to build larger values. The game begins with smaller numbers like 1, 2, and 3. When two or more of the same numbers are next to each other, players can click to combine them into the next number in the sequence, and the new number appears in the space they selected. The more matching numbers that are grouped together, the more efficiently players can clear space and create higher numbers. This game supports K–5 math learning by strengthening number sense, addition concepts, and pattern recognition. Players begin to understand how numbers grow and relate to one another while also practicing strategic thinking, as they decide when and where to combine numbers for the greatest impact. It also builds problem-solving skills as students plan moves and predict outcomes to reach the goal of creating 11.
