Free activities to inspire tomorrow’s innovators and inventors

Motivate your students to discover, connect and understand concepts in math, science, engineering design and coding with project-based lessons for Texas Instruments graphing calculators and TI-Innovator™ technology.

Set in real-world contexts, these innovative activities are ideal for middle grades and high school classrooms, after-school programs, clubs, summer camps and special STEM events.

Free support for STEM Projects

  • Curriculum materials
  • Online training videos
  • Emails and phone call access to TI STEM experts
  • Technical support
  • Loan of individual project kit(s) for instructor preparation
  • One-two week equipment loans for student use (as necessary)

Develop skills for 21st century success

Strengthen students’ critical thinking and creative problem solving abilities as they work through STEM Projects using TI-84 Plus CE or TI-Nspire™ CX graphing calculators and the TI-Innovator™ Hub with TI LaunchPad™ Board.

TI-Innovator Rover
Take the on-ramp to robotics 

When the wheels are turning, students are learning. The TI-Innovator™ Rover—controlled by a Hub that is programmed with TI graphing calculators—puts math and science in motion.


Unit 1: Destination Mars

The Mars Rover Challenge (Motion) introduces students to the coding and hardware-control practices and processes NASA engineers use to keep a remotely operated vehicle on track while exploring another planet.
