    Inferring Through Imagery and Figurative Language

    • Resource ID: TXLS150
    • Grade Range: 9
    • Subject: ELA & Reading

    Students rotate to four posters which contain a single stanza from a common poem ("Digging" by Seamus Heaney ), marking key literary elements (imagery, diction, figurative language) before rotating to explain the connotation of the words and phrases selected by the previous group. After text marking, students regroup to discuss the inferential connections between literary terms and their connotative meaning to theorize thematic meaning within the poem.

    Going on an Expedition

    • Resource ID: TXLS127
    • Grade Range: 5
    • Subject: Science

    Students observe how dunes and canyons are created through agents of erosion by weathering and erosion.

  12. Explore Revising and Editing with some Classroom Adventure

    • Resource ID: TXLS112
    • Grade Range: 1
    • Subject: ELA & Reading

    While “scooting” from one example to another, students will explore sentences in order to determine what end punctuation is necessary and why. Students will also collaborate to explore sentences in order to identify what edits are necessary and why.

  13. Organizing Olympic Outcomes
