This task has algebra students investigate how the distributive property works without giving the student the rule of distribution. Students must compare two different number rules involving both addition and multiplication and construct an argument as to why both rules generate the same number. The task provides an outline for a student response. The task does provide space for students to make a claim and it asks followup questions that allow students to explain the claim.
