Mystery Jars

This is a twist on the old "guess how many jellybeans" game. Using estimation and math skills, learners participate in a fun "mystery jars" activity, trying to make educated guesses at how many objects are in two jars. The basic activity includes filling two jars, one with smaller objects and one with larger. Scholars record their estimates, explaining why they feel this way. Guide thinking to reveal processes learners used. Extensions and variations are included to expand on math skills.
