Here is a draft lesson plan for introducing metamorphic rocks to a general level freshman high school earth science class:
Topic: Introduction to Metamorphic Rocks
Objectives:

• Students will be able to define what a metamorphic rock is
• Students will understand the processes that form metamorphic rocks
• Students will be able to identify some common metamorphic rocks and their parent rocks

Materials Needed:

• Samples of metamorphic rocks like slate, schist, gneiss, quartzite, marble
• Handout with descriptions and visuals of the different metamorphic rocks
• Projector and slides

Intro (10 mins):

• Ask students what they already know about rocks and how they form
• Explain that we'll be learning about a new category - metamorphic rocks

Lecture (20 mins):

• Define metamorphic rock - formed from pre-existing rocks due to intense heat, pressure, or chemical activity
• Describe processes that cause metamorphism like high heat/pressure from burial, extreme compression from plate collision, hot fluids
• Show visuals of the 3 main types: foliated, non-foliated, in between
• Give examples of common metamorphic rocks and their parent rocks:
  • Slate from shale
  • Schist from mudstones/shales
  • Gneiss from granite/other igneous rocks
  • Quartzite from sandstone
  • Marble from limestone

Activity (15 mins):

• Pass out metamorphic rock samples and handout
• Have students examine the samples, identify textures/minerals, and match to the descriptions

Wrap-Up (5 mins):

• Review the key points about how metamorphic rocks form
• Have students give examples of metamorphic rocks and what they form from

This introduces the basics of metamorphic rock formation, identifying some common types, and allows hands-on practice linking the rocks to their descriptions. It could be supplemented with additional visuals, videos, or readings as well.
