Fill in the spaces with Spanish vocabulary words and their corresponding English translations. Then hand write in the numbers 1-25 randomly on the squares. Cut the pieces out and students will put the puzzle together by matching translations. When they are done, they have to fill in the numbers on their answer sheets.
There are two versions included. In the first version, there are no words written on the edges. This is the easier version. In the second version, there are words written on all sides and students will not know which words are edge pieces until they have completed the puzzle.
I usually use different colors of paper for each version and have students work in pairs.
