On Oct. 21, fifth-graders in Eric O'Brien's class explored the geometric patterns on a checkerboard as part of a mathematics lesson. “When asked how many squares were on the board, students quickly answered, ‘sixty-four’," said Mr. O’Brien.

Upon further examination, the students discovered that the checkerboard contained squares of all sizes, beyond the 64 they had initially observed. As they worked cooperatively, they counted squares and built patterns that led them to a final answer and more problems to ponder. The activity encouraged the students to apply their conceptual understanding and problem-solving skills, allowing them to gain a deep understanding of this mathematical concept.
