Lasting Impact of an LT-based Scale-up Model on Math: Persistence, Sustainability, and Diffusion

Learning and Teaching with Learning Trajectories

Learning and Teaching with Learning Trajectories (LTLT or [LT]2) is a free tool for early childhood educators to learn about how children think and learn about math and how to teach math to young children “their way” (birth to age 8). [LT]2 allows teachers, caregivers, and parents to see and use learning trajectories for math, as they view short video clips of good teaching as well as children working on math problems in a way that clearly reveals their thinking. [LT]2 runs on all technological platforms, includes alignments with standards and assessments, and includes hands-on and built-in software for children. [LT]2 enables teachers to help children find the math in—and develop the math from—their everyday activities, including art, stories, puzzles, and games.
