Students will help choose the best value of connecting blocks by developing a procedure based on the following criteria: color, ease of use, variety of blocks, and number of blocks per set. They will reassess these blocks during the twist incorporating a new type of block. They will need to calculate the total costs of each set of blocks.

Students may arrange the criteria based on their teams’ interpretation of most important to least important. Students may have to make trade-offs based on these interpretations (i.e., price versus the other criteria in the data sets).

Model Eliciting Activities, MEAs, are open-ended, interdisciplinary problem-solving activities that are meant to reveal students’ thinking about the concepts embedded in realistic situations. Click here to learn more about MEAs and how they can transform your classroom.
