South Dakota English Language Arts Standards (2025)

Teacher's field guide

What Students Need to Do: Students read or listen to two nonfiction texts about the same topic. They tell what each text mostly teaches, then explain how those main ideas are alike and different.
What Mastery Looks Like: A student states the main idea of each text in their own words. They name one way the ideas connect and one way they differ, using information from both texts.
Common Misconceptions: Students may give one fact, such as 'bees have wings,' instead of the idea the whole text teaches. They may say two texts have the same main idea just because both mention bees.
How to Assess It: Give students two cards: 'Bees move pollen between flowers and help plants grow' and 'Bees collect nectar from flowers and make honey.' Ask them to write each card's main idea, then say how the ideas are alike and different.

Lesson moves

Give pairs a short bee article about honey and another about pollination, then use sticky notes to map each main idea and an overlap.
After reading two short texts about rain, ask: 'What does each teach about rain, and how are those ideas alike and different?'
Read two animal fact cards, then award teams points for naming both main ideas, one similarity, and one difference.
Print two school lunch flyers, one about choosing fruit and one about wasting less food, then compare their main ideas.
