Finding Math Inference activities are rare, but here is a sample. The neat thing about inference scenarios are that the kids think of the questions!
This is a whole class activity and takes approximately 30 minutes.
It reinforces the Common Core State Standards for Mathematical Practice. It helps the children analyze givens, constraints, relationships, and goals. It reinforces making sense of quantities and their relationships. This inference practice will help children understand and use stated assumptions and have the children justify their conclusions. They will reason inductively about the data and make arguments taking into account the context of the data. They will be modeling problems that arise in everyday life and solve problems with various methods.
