Stretch Sums is a logic-based math puzzle game where players must clear every tile on the board by making numbers balance to zero. Players can only move the red plus (+) circles, and each move changes their value, helping students explore subtraction, addition, and number relationships in a hands-on way. As red tiles are dragged across the board, their values decrease by one for each space moved, encouraging learners to count, predict outcomes, and think carefully about distance and value. Blue minus (–) squares stay fixed, requiring students to plan how to combine positive and negative values so they cancel out exactly. In later levels, green minus tiles introduce deeper strategy by transforming red values into new negative tiles. Designed for K–5 learners, Stretch Sums builds number sense, logical reasoning, and problem-solving skills through strategic planning and flexible thinking.
