Mr. Peters is using the Sheltered Instruction Observation Protocol (SIOP) Model with his sixth-grade math class, which contains four ELLs. What should Mr. Peters do during the interaction phase?

• A. Group students together with varied English levels and content knowledge
• B. Group students by language proficiency only
• C. Have students work independently
• D. Group students by content knowledge only

Answer: (A)

In the interaction phase of the SIOP model, students learn best when they talk with and learn from each other as they work on content tasks. Grouping students with varied English levels and different background knowledge creates a dynamic environment where peers can model language, fill gaps in understanding, and provide scaffolding. Stronger English speakers can demonstrate appropriate vocabulary and sentence structures, while students with stronger content knowledge can explain math concepts in context. This mix helps everyone practice academic language in meaningful math discussions and supports deeper understanding through collaborative dialogue and peer feedback.

Grouping by language proficiency only limits opportunities for practicing math discourse with peers who can model both language and math thinking. Having students work independently reduces the essential interactive practice that builds language and content skills. Grouping by content knowledge only can leave language needs unaddressed, making it harder for ELLs to participate effectively in the discussion.
