Custom Professional Development

Through Heinemann, TTA authors offer districts custom professional development for teachers in grades 6-10 who want to:

  • better support their students’ learning of algebra, particularly students who may be struggling in mathematics,
  • learn more about the Common Core State Standards for mathematical practice in the context of building early ideas in algebra, and
  • engage with materials designed to foster algebraic habits of mind.

Professional development supports the use of Transition to Algebra. Teachers will learn about the TTA habits of mind approach and the mathematical storyline of the curriculum. Teachers will engage with mathematical activities from the units and discuss student difficulties and share instructional strategies. For more information, please contact us.
