A strong understanding of fractions is vital to later success in mathematics. However, research has consistently shown that fractions are one of the most difficult mathematical concepts for elementary school students to master. To attempt to remedy this deficit, the authors began a project called Helping At-risk students Learn Fractions (HALF) in…

Knowledge of the equal sign as an indicator of mathematical equality is foundational to children's mathematical development and serves as a key link between arithmetic and algebra. The current findings reaffirmed a past finding that diverse items can be integrated onto a single scale, revealed the wide variability in children's knowledge of the…
