We complete a STEM Engineering Challenge once a week in our classroom! I compile all of the materials I need for the challenges into plastic tubs along with the lab sheets. For each STEM Engineering Challenge that is not individual, the members of the team need to have specific roles. These are the sheets I use for these roles. I post them in the classroom after I print them on colored paper and laminate them, of course! I also make smaller card versions to use with each table (these are also laminated and printed on colored paper). I use the cards both when students randomly choose their roles and when I assign the roles. Having the card with the role expectations with them during the challenge solves a lot of the issues that occur during a STEM challenge! Click here for the link to this freebie!
I hope you can use this freebie in your classroom!
