## Summary

Like algebra at any level, early a=
lgebra is a way to explore, analyze, represent, and generalize mathematical=
ideas and relationships. This book shows that children can and do engage i=
n generalizing about numbers and operations as their mathematical experienc=
es expand. The authors identify and examine five big ideas and associated e=
ssential understandings for developing algebraic thinking in grades 3 5. Th=
e big ideas relate to the fundamental properties of number and operations, =
the use of the equals sign to represent equivalence, variables as efficient=
tools for representing mathematical ideas, quantitative reasoning as a way=
to understand mathematical relationships, and functional thinking to gener=
alize relationships between covarying quantities. The book examines challen=
ges in teaching, learning, and assessment and is interspersed with question=
s for teachers reflection.
