This book focused on determining the ways in which numeracy skills are enhanced through tangram. An exploration on ways of solving patterns in tangram, power of imagination, enhancement of logical, analytical and critical thinking, and desirable characteristics being formed in playing tangram became part of this book. The community quarantine in the Philippines due to COVID-19 caused the design of this book to gather data through online tangram tournament. Seven learners accepted the seven-day challenge. They solved 55 tangram puzzles and answered 6 qualitative questions. After a week of tangram challenge, significant findings were established.
