- distribute the same tetromino to each student and repeat the activity in another lesson,
- distribute a different tetromino to each student,
- distribute identical or varied tetromino to different groups.
Answer Key
After assembling the tetromino, check the result using the answer key at the end of the document. The key shows the correctly assembled tetromino. The squares on the students’ sheets are shuffled randomly.
