Prepositions of place are among the first things English students learn — and among the last things they get right. Students often confuse in, on, and at, and rarely learn the less common ones well. In this session, you will explore why these errors happen, deepen your own understanding, and find practical activities to use in class immediately.
Before you start — think honestly about your own teaching and experience.
Look at the examples. Answer each question before reading the explanation — this is how your students will learn too.
Look at these pairs of sentences. Both sentences in each pair are correct. What is the difference in meaning or situation?
'In' describes something inside a space — surrounded on multiple sides. 'On' describes something resting on a surface — touching the top of something. This is the most fundamental distinction. The cat inside the box is enclosed. The cat on top of the box is on a surface. This distinction is the foundation of prepositions of place: enclosed space vs. surface.
Now look at these sentences and think about how 'at' is different from 'in'.
'In' focuses on the physical interior of the building — she is inside the school building. 'At' focuses on the location as a general point — she is at that place, that destination. We often use 'at' for places where an activity happens (at school, at work, at the bus stop, at the market) and 'in' for the physical space inside a building or area. 'She is in the school' = inside the building. 'She is at school' (no article) = she is there for the purpose of school.
Look at these sentences. What do the underlined prepositions tell you about position? Can you describe the meaning of each one in your own words?
Under = lower than something, with something above it. Next to = directly beside something, on either side. In front of = further forward than something, facing it. Behind = further back than something, on the other side. Between = in the space that separates two things. These prepositions are best taught with physical demonstration — use objects in your classroom. Abstract definitions are much harder to remember than a physical experience.
THE IN / ON / AT PROBLEM: These three cause the most errors because students often translate from their first language, which may use one preposition where English uses two or three.
A useful question to ask yourself — and to teach students:
- Is it INSIDE something? → in
- Is it ON TOP OF a surface? → on
- Is it a PLACE or DESTINATION (not focused on inside)? → at
Point to something in the room. Ask: Is it INSIDE something? ON a surface? Or just AT a location? If students can answer this, they can choose the right preposition.
Choose the correct preposition to complete each sentence. Click the option you think is right — then read the explanation.
Each sentence below contains an error. Write the correct sentence in the box and explain why it is wrong — then reveal the answer to check.
Use this sequence directly in class — guided discovery, no textbook needed. Tap each step to mark it done.
STEP 1 — PHYSICAL DEMONSTRATION (5 minutes): Use any object in your classroom — a pen, a bag, a book. Place the object in different positions and ask students to describe where it is. Do not give the prepositions first. Ask: 'Where is the pen?' Students attempt answers. Confirm or correct. This anchors the vocabulary in physical experience before any rule is introduced.
STEP 2 — STUDENTS BUILD THE RULES (8 minutes): Write the prepositions on the board: in, on, at, under, next to, in front of, behind, between. Ask students in pairs: 'Can you write one sentence for each preposition — using something in this classroom?' Students write sentences, then share. Correct gently. The act of generating sentences themselves produces much stronger memory than copying examples.
STEP 3 — DESCRIBE THE CLASSROOM (5 minutes): Ask students to describe the classroom to a partner — where is everything? Use this as a fluency activity. Listen and note errors for the next step.
STEP 4 — ERROR CORRECTION IN PAIRS (5 minutes): Write four sentences on the board — some correct, some wrong. Students work in pairs to find and correct the errors. This consolidates the rules without feeling like a test. Share and discuss answers as a class.
STEP 5 — DESCRIBE YOUR HOME (optional extension, 5 minutes): Ask students to describe a room in their home. Where is the bed? Where is the table? This personalises the language and produces natural, motivated use of prepositions.
Use directly in class — copy, adapt, or read aloud. No printing needed.
For each strategy, choose the option that best describes where you are now.
