Tips to be successful in ATYP Geometry!

ALWAYS prepare for your next class! When reading new sections to be discussed in class ~

  • Pay attention to what the book calls “New Vocabulary.” Some words or concepts may be familiar (highlighted in yellow). The definition or usage in Geometry may be a little different than areas outside of mathematics or in science. For each new vocabulary word, think about how the concepts can be demonstrated in an shape or an example.
  • Read through the introduction of each new section. Study the processes in each example. Come to class with questions about what you’ve read or about specific problems in homework (can also email during week before class). After the school year starts, you will want to exchange phone numbers so you can also ask classmates to study groups or to work together over the phone.
  • ALWAYS …Bring completed homework to class along with any work done (show your work!), stapled together, in order by section, put your name and due date on top of the first page, initials thereafter. If it took more than one step in your head, then SHOW YOUR WORK and circle the answer reached. Remember: neatness counts!
