In Ms. Prieto's integrated lesson, what activity best supports ELLs' language development alongside their content knowledge?

The activity of writing a shopping list with prices for individual items is effective for language development alongside content knowledge because it combines practical application with critical thinking. This task requires ELLs to engage with vocabulary and phrases related to everyday items, prices, and the context of shopping, all while using the target language.

As students create a shopping list, they practice not only their writing skills but also learn how to categorize items, understand numerical values, and interact with real-world scenarios that enhance their comprehension of both language and math concepts. This type of activity encourages them to use language in a meaningful context, solidifying their understanding of vocabulary and sentence structure related to shopping, which is a familiar and practical theme in their daily lives.

Additionally, it promotes cognitive engagement as students contemplate what they 'need,' reinforcing vocabulary acquisition and usage through a task that mirrors real-life situations.
