STEM Lessons - Model Eliciting Activity
Students use problem solving skills, data sets presented in a chart, two and three digit addition, writing skills and money skills to determine which brand of jelly beans they would like to purchase. The jelly beans differ in taste, quantity, and cost. The students must then check their procedure to determine if it will work when given an additional piece of data.
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.
After reading, Officer Buckle and Gloria the students will be given a problem showing different ways safety problems have been solved at area schools. Through ranking, they will have to determine which manner was the most effective.
