Third- through fifth-grade students participating in a classroom teaching experiment investigating the impact of an Early Algebra Learning Progression completed pre- and post-assessments documenting their abilities to represent or describe unknown quantities. We found that after a sustained early al...

Zusammenfassung:Third- through fifth-grade students participating in a classroom teaching experiment investigating the impact of an Early Algebra Learning Progression completed pre- and post-assessments documenting their abilities to represent or describe unknown quantities. We found that after a sustained early algebra intervention, students grew in their abilities to represent related unknown quantities using letters as variables.
