First Day of High School Geometry Activities

Instructor: Maria Airth

Maria has a Doctorate of Education and over 20 years of experience teaching psychology and math related courses at the university level.

Fun, game-like activities allow students to bond while refreshing their memory on certain concepts. These activities are great ice-breakers for high school students entering Geometry.

Ice-breakers for the First Day of Geometry

The first day of any class can be difficult, but Geometry is one of those classes that many students seem to dread. A great way to help ease your students into the concepts they will learn in Geometry is to make the first day full of games and fun. Group activities will help your students bond over what they know and don't know about the coming year.

These activities are designed for high school students entering Geometry.


Charades is a great game to play to get your students active and having fun with math concepts.


  • Concept cards (at least 1 per student) like:
    • cube
    • right angle
    • angle
    • sphere


  • Divide your class into even groups of 4-5.
  • Instruct your students to sit with their groups.
  • Put the stack of concept cards upside down near the front of the room.
  • To start, the first player in the first group will choose a card and go to the front of the room. Then,
    • The player must use actions only (no drawings or spoken words) to try to express the concept on his/her card.
    • If a student from the player's team guesses the answer first, his/her team gets 2 points.
    • If a student from another team guesses the answer first, that team gets 1 point.
  • Next, a player from the second group replaces the first player at the front, draws a card and repeats the actions.
  • Play passes from one group to the next until all students have had a chance to act out the charade concept cards.
  • The team with the most points wins and your students have refreshed/reviewed a large number of concepts needed for their coming Geometry course.


  • This game could be played in pairs with timed rounds.

Mathematical Art

Allowing students to be creative with math helps to connect them to the coming material.


  • Ruler
  • Compass/protractor
  • Pencils (colored and lead)
  • Concept cards (1 per student)
  • Blank paper


  • Ensure that all students have a set of materials.
  • Hand out concept cards to your students randomly.
  • Instruct your students to first draw the concept they were given and then use that drawing as the foundation of a creative art picture. For example:
    • If a student received 'right triangle' on his/her concept card, he/she might turn that into the roof of a house in an artistic drawing.
    • A sphere could be turned into the eye of an alien.
  • When everyone has finished, encourage your students to share their work and see if the class can guess what the original image (concept card) was.
