Here is a SER/ESTAR dice game in PDF form.
Kids have Spanish subject pronouns with the words (SER/ESTAR) in the left column and then Spanish places/descriptions in the right column. Student would roll the die 2 twice during their turn. If they got a 1 and a 4 for example, the would have to conjugate
die #1--left column "Yo (SER/ESTAR)"
die #4--right column "estudiante(s)"
= Yo soy estudiante.
Kids compete against each other to see who can conjugate the most verbs correctly.
The answers to the dice game are on the second page; copy the answers to the back of the game card so that students can check their partner's answers for accuracy.
