The Transition to Algebra (TTA) curriculum seeks to quickly give students the mathematical knowledge, skills, and confidence to succeed in a standard first-year algebra class and to show them that they can explore mathematics and actually enjoy it. TTA is a full-year algebra support curriculum that can run concurrently with first-year algebra. It is designed to build students' algebraic habits of mind as they explore algebraic logic puzzles that connect to and extend algebra course topics and learn broadly applicable tools and strategies to help them make sense of what they are learning in algebra. Students discuss and refine their ideas as they work through mental mathematics activities, written puzzles, spoken dialogues, and hands-on explorations that engage them in cultivating mathematical knowledge, intuition, and skills.
