Lesson plan

Warm-up

5 min

Mouse-and-box demo: teacher places a toy mouse IN, ON, UNDER, BEHIND, BESIDE, BETWEEN the box. Children call out the preposition for each placement.

Teacher moves
  • Affirm exact preposition
  • Catch 'inside' vs. 'in' as fine-grained alternatives
  • Bridge to phrases not just single words

Direct instruction

13 min

Today we meet PREPOSITIONS. A preposition is a small word that begins a PHRASE telling us WHERE (location) or WHEN (time). Location: in the box, on the chair, under the bed, behind the door, beside the pond, between the trees. Time: before lunch, after recess, during math, until Friday. The preposition ALONE isn't the phrase — you need the noun phrase after it too: 'in the box' is the phrase. Try this in your opinion paragraph 2: your example sentence can hold a prep phrase. 'I helped Mateo find a book on the shark shelf' has the prep phrase 'on the shark shelf' telling WHERE.

Key examples
  • Each phrase tells the reader something different — one tells where, the other tells when.
    model PREP PHRASE 1: 'under the maple tree' (location). PREP PHRASE 2: 'at recess' (time). Notice this sentence has TWO prep phrases — that's fine.
    prompt Identify the prep phrase: 'I sat under the maple tree at recess.'
  • Add a phrase that fits your example.
    model Options: 'I ate the sandwich on the bench / in the cafeteria / before science / after gym.' Pick ONE.
    prompt Add a prep phrase to: 'I ate the sandwich.'
Checks for understanding
  • Is 'under' a phrase or just a preposition?
  • Add a time prep phrase to 'I helped Mateo.'

Reproduction of MG-5 at 11x17: top half shows 8 mini-illustrations of a cartoon mouse interacting with a single brown box — 'in the box' (inside, peeking out), 'on the box' (on top), 'under the box' (peeking from below), 'behind the box' (just an ear visible), 'beside the box' (next to it), 'between the boxes' (squeezed between two), 'above the box' (hovering), 'below the box' (in a hole beneath). Each scene labeled with the preposition phrase. Bottom half shows a clock+calendar with 4 time-prep phrases: 'before lunch' (clock arrow before 12), 'after recess' (clock arrow after 10:30), 'during math' (clock highlighting 9-10), 'until Friday' (calendar Mon-Fri with arrow). Print-ready, dyslexic-friendly font.

Guided practice

12 min
Tasks
  • With the mouse-and-box, demonstrate 6 prep phrases physically. Partner narrates with the full phrase.
    scaffold MG-5 anchor visible; preposition word cards on table
  • Open your paragraph-1 draft. Add ONE prep phrase to your example sentence. Annotate as ADD DETAIL — prep phrase.

Photo of the recommended classroom manipulative kit: one 2-inch cardboard box (brown), one small toy mouse figure (2 inches), one preposition card deck (8 cards: in, on, under, behind, beside, between, above, below). Used by pairs to act out and narrate. Print-ready 4x6 photo for catalog reference.

Formative assessment

3 min
Exit ticket
  • Add a prep phrase to: 'I read my book.' Pick WHERE or WHEN.
scoring Complete prep phrase (prep + noun phrase) = mastery; single preposition only = practicing; nothing or unrelated = reteach.

Closure

2 min
Moves
  • Read your prep-phrase sentence aloud.
  • Predict: tomorrow we draft paragraph 2 with prep phrases.

Homework

10 min
Tasks
  • Find one prep phrase in a book at home. Write the phrase and label LOCATION or TIME.

Teacher notes

Prepositions are a Year-3 NC expectation; we are introducing them at G2 Spring to deepen sentence-expansion craft. Children almost always understand prepositions intuitively — they USE them daily in speech. The new work is METALINGUISTIC: naming them, recognizing the full phrase (not just the preposition word), and embedding them as a craft move in writing. Plan to revisit in lessons 11 and 12.
