After students have been introduced to cells and cell parts they can use their knowledge to complete this puzzle. The puzzle covers cell parts (description of organelles, pictures of organelles, cell theory, cell types, etc.). The puzzle is assembled correctly on the downloadable sheet, so when giving to students it needs to be cut out ahead of time. Words, pictures or descriptions may be paired together. There may be multiple ways to fit it together but the challenge is to make it a 3x4 grid. Print onto card stock or laminate for durability.
