Description Structure — Painting a Topic for the Reader

Objectives
  • Students identify the DESCRIPTION text-structure in a mentor-text informational paragraph.
  • Students draft a description-structured TDET body paragraph for their expert topic, using at least 3 sensory or feature-naming details.
Vocabulary

Lesson plan

Warm-up

5 min

Mentor-text close-read: teacher reads aloud a paragraph from Sandra Markle that DESCRIBES an animal feature (e.g., octopus tentacles, beaver teeth). Children listen for: how does the writer organize? What kind of details are used?

Teacher moves
  • Read with informational-narrator voice
  • Pause and name: 'this is DESCRIPTION text-structure'
  • Ask: 'What kinds of details did Markle use?' (color, size, function, comparison)

Reference image to accompany the Markle honeybee paragraph: close-up watercolor of a honeybee on a sunflower, with labeled callouts (size '~half inch', wings 'clear, 2 pairs', tongue 'long proboscis for nectar'). Used so children see the features 'lived' before they write their own. Print-ready 8.5x11.

Direct instruction

12 min

Informational writers organize their writing in 5 main TEXT STRUCTURES — patterns for arranging ideas. Today we meet the FIRST: DESCRIPTION. A DESCRIPTION paragraph names a topic and then paints a picture of it for the reader using FEATURES — color, size, shape, sound, smell, function, parts. Description fits topics where you want the reader to PICTURE something or KNOW WHAT IT IS LIKE. Watch the model. (Teacher reads aloud) 'Honeybees are about half an inch long, with golden-orange and black stripes across their bodies. They have two pairs of clear wings that beat 200 times per second, making the buzzing sound you hear in a garden. Their long, straw-like tongues, called proboscises, let them drink nectar from deep inside flowers.' Notice the FEATURES Markle uses: SIZE (half an inch), COLOR (golden-orange and black), PARTS (wings, tongue/proboscis), FUNCTION (drink nectar, make buzzing). A description paragraph layers FEATURES until the reader can picture the topic.

Key examples
  • Description = FEATURES. Size. Color. Shape. Parts. Function. Layer at least 3.
    model TOPIC (purple): 'The moon jelly is one of the most common jellyfish in the ocean.' DETAIL (blue): 'Moon jellies are about the size of a dinner plate, with a clear, dome-shaped body and four pale-pink rings inside that look like a four-leaf clover.' EXAMPLE (orange): 'For example, at the New England Aquarium, dozens of moon jellies float gently in a round tank that visitors can walk around.' TRANSITION (green): 'Besides their unusual look, moon jellies also have a surprising way of feeding.'
    prompt Teacher writes a description-structure TDET paragraph from scratch about a new topic (a specific kind of jellyfish — the moon jelly).
Checks for understanding
  • Name 3 kinds of FEATURES you might use in a description.
  • When does DESCRIPTION fit a topic better than SEQUENCE?

M-3-S-WR-05-A Chart Physical / non-image

11x17 anchor with the word DESCRIPTION at the top in large color-block letters, and below 7 feature-icons in a circle (size = ruler, color = paint palette, shape = geometric shapes, sound = ear, smell = nose, parts = puzzle piece, function = gear). Below the circle: a 1-paragraph worked example (the moon jelly) with each feature word underlined in green. Print-ready, dyslexic-friendly font.

Guided practice

15 min
Tasks
  • Pick a body-paragraph focus from your roadmap that calls for DESCRIPTION (e.g., 'what honeybees look like', 'how octopuses move'). Draft a TDET paragraph using 3 features.
    scaffold Features word-bank (size, color, shape, sound, smell, parts, function) at desk
  • Annotate the 3 features in your draft with a green pencil — underline each feature word.
    scaffold Green pencil + feature word-bank

Formative assessment

4 min
Exit ticket
  • Read your description paragraph aloud to a partner. Partner names: 3 features and the text-structure.
  • Star the strongest feature.
scoring 3 features named + description identified = mastery; 2 features = practicing; 0-1 = description reteach in lesson 6.

Closure

2 min
Moves
  • Hold up your description paragraph.
  • Predict: tomorrow we draft body 2 — and we may use a different text-structure.

Homework

10 min
Tasks
  • At home tonight, pick one ORDINARY object (a tool, a piece of fruit, a household item). Write 3 sentences DESCRIBING it using features: size, color, function. Bring it to share tomorrow.

Differentiation

Scaffolds
  • Pre-printed feature word-bank at desk
  • MG-3 TDET anchor + description-structure cue card
  • Partner-talk to brainstorm features first
Extensions
  • Use 5 features instead of 3.
  • Add a comparison feature ('Moon jellies are about the size of a dinner plate').
English Learners
  • Bilingual features word-bank
  • Visual prompt (photo of topic) at desk for non-readers
  • Oral feature-naming before writing
Ieps 504s
  • Drawing-with-feature-labels acceptable as a description-paragraph alternative
  • Reduced target: 2 features instead of 3
  • Adult scribe

Teacher notes

Description is the most accessible text-structure for G3 because it borrows from the sensory-detail work of fall narrative. Children who can layer features without overwhelming the reader will write strong description paragraphs across the term. Watch for the 'random feature' problem — listing features in no order (size, smell, sound, color, function) feels scattered. Encourage a loose order: BIG-TO-SMALL (whole organism → parts) or LOOK-TO-FUNCTION (appearance first, then what it does). The MG-3 TDET anchor combined with the features word-bank is the highest-leverage scaffold for this lesson.
