SoE:
SoE are systematic, but they are not a procedure. They're comprehension tools to help students visualize and understand a story problem and make sense of what is being asked. The process can not be reduced to a sequential series of steps.
Repeated Equal Group Structures are helpful if a math story describes putting equal groups together or taking equal groups apart (compose/ decompose)
Parts Equal Total Structures are helpful if a math story describes 2 or more parts being put together (composed) to form a total or when a story describes a total being taken apart (decomposed) into 2 or more parts.
Compare Structures are helpful if a math story describes a situation where quantities are being compared.
You’ll need to put work in up front to introduce the structures and help students internalize them. There’s no cute worksheets or clever acronyms. And no tricks. But with explicit instruction and consistent use, you’ll have students with the tools and confidence to attack word problems on their own.

“Julie Russo researched how to teach children mathematics and adapted some of the best ideas into the Structures of Equality (c). You have heard of Singapore Bar Models, tape diagrams, and graphic organizers. These are all great tools. But what Julie does is connect reading to mathematics in a way that is clear, effective and achievable in any classroom. In particular, "The Line of Equality," engages students in conversations that develop both reading comprehension and number sense.”
