Reflection: Checks for Understanding Inequality Applications - Section 3: Summary


At least and at most are two of the most difficult phrases for students to wrap their brains around.  During class, I tried to remind kids to continually put the phrase into a context they understood so that they could better assign an inequality symbol.  For example, you have to be "at most" 12 years old to order off the kid's menu, or you have to be at least 16 to get driver's license.  That seemed to help.  During the table discussion I heard a lot of students using those examples, so hopefully it will stick with them!
