5th and 6th graders worked on The Domino Pyramid Puzzle, created by L. P. Mochalov. The Domino Pyramid Puzzle is a hands-on challenge that combines logical thinking, mathematics, and teamwork. The objective of the puzzle is to arrange a complete set of dominoes into a pyramid-shaped template while following two rules.
The first rule requires that the total of each horizontal row in the pyramid must equal a perfect square. This introduces participants to an important mathematical concept, as they must recognize and calculate perfect squares such as 1, 4, 9, 16, and beyond. The second rule follows traditional domino logic: any dominoes that touch horizontally must have matching numbers on the sides that meet. Together, these rules create a puzzle that requires careful planning, calculation, and cooperation.
Despite having only two rules, the puzzle offers a rich learning experience. Participants actively engage with mathematical concepts, particularly the idea of perfect squares and how numbers can be combined to achieve them. Rather than learning through memorization, players apply math skills in a practical and interactive way.
Beyond mathematics, the Domino Pyramid Puzzle strongly encourages teamwork, communication, and problem-solving skills. Players often work in groups, where everyone must contribute ideas and strategies to complete the puzzle successfully. Because groups are randomly assigned, participants must quickly learn to collaborate, listen to one another, and work toward a shared goal. Players must continuously test solutions, adjust their approach, and ensure that neither rule is broken. This trial-and-error process encourages critical thinking and persistence, making the puzzle both challenging and rewarding.
