Reading a Model of the Land
A 50-minute Grade 2 lesson on building and reading a model that shows the shapes and kinds of land and water in an area.
Reading a Model of the Land is a free 50-minute Grade 2 science lesson plan for Common Core standard 2-ESS2-2 — model the land and the water in an area. It is timed across 5 sections, gives the exact wording to use where the wording carries the mathematics, names 3 misconceptions with the teaching move that addresses each, and ends with an exit ticket and a printable worksheet with its answer key.

2-ESS2-2
Develop a model to represent the shapes and kinds of land and bodies of water in an area.
Objective
Students will be able to build a model of an area and say what each part stands for.
Students are successful when they can
- Shows land and water differently.
- Includes a key saying what each part means.
- Says one thing the model does not show.
What you need
- Trays, modelling clay, blue paper or foil, green paper, card for labels
- A simple map or aerial photograph of the local area
- The printable practice sheet linked at the end of this plan
The lesson
Warm-up — what is the blue bit?
5 min- Show a model with unlabelled blue and green areas.
- Ask what the blue is, and let the guesses disagree.
Teach — build it, then key it
13 min- Shape a hill from clay and a valley beside it.
- Lay a blue ribbon down the valley and call it a river.
- Add a flat blue patch and call it a lake.
- Write a key: blue ribbon means river, blue patch means lake, lump means hill.
- Ask why the key matters. Without it, nobody else can read the model.
- Ask what the model does not show: how high the hill really is.
“What does this part stand for? Is that in the key?”
Investigate — model the local area
17 min- Groups build a model of a real local area from a map or photograph.
- They show at least two kinds of land and two kinds of water.
- They write a key with a line for every symbol used.
- They swap models and try to read another group's using its key alone.
Independent practice
12 min- Students complete the 'Reading a Model of the Land' page.
- Check every match names what the part represents.
Close
3 min- Ask what a visitor could learn from the class model.
What goes wrong, and why
Each of these is a reasoning error rather than carelessness. The fix addresses the reasoning.
Builds a model with no key.
Why: The maker knows what everything is.
Fix: Swap models. What is obvious to the maker is invisible to the reader.
Thinks the model shows real sizes.
Why: It looks like the place.
Fix: Ask how high the clay hill is in real life. A model is smaller and simpler.
Uses blue for everything wet and green for everything else.
Why: Two colours are easy.
Fix: A river and a lake are different kinds of water. Show the difference.
If they are not there yet
- A pre-shaped tray with parts to place and label.
- Key cards to match to the model.
If they finish early
- Add a feature your map shows that your model cannot.
- Model the same area as it would look after a flood.
- Write directions across your model using its key.
Exit ticket
On your model, what does a blue winding ribbon stand for, and why does the model need a key?
What to look for: A river, and a key so somebody else can read it. A model with no key named means the reader point needs another run.

Questions about Reading a Model of the Land
How long does the Reading a Model of the Land lesson take?
50 minutes, split across 5 timed sections: warm-up 5 min, teach 13 min, investigate 17 min, independent practice 12 min, close 3 min. The minutes are stated per section and add up to the stated length, so the plan can be cut or extended at a section boundary rather than abandoned halfway.
Which standard does Reading a Model of the Land teach?
2-ESS2-2 — 2-ESS2-2, Earth and Space Science for Grade 2: “Develop a model to represent the shapes and kinds of land and bodies of water in an area.” In plain terms, model the land and the water in an area.
What do I need to teach this lesson?
Trays, modelling clay, blue paper or foil, green paper, card for labels, a simple map or aerial photograph of the local area and the printable practice sheet linked at the end of this plan. Everything listed is either ordinary classroom equipment or a free printable from this site — there is nothing to buy and nothing to prepare beyond photocopying.
What mistakes should I expect in this lesson?
Three, each a reasoning error rather than carelessness: builds a model with no key; thinks the model shows real sizes and uses blue for everything wet and green for everything else. The plan gives the thinking behind each one and the teaching move that addresses the thinking rather than the symptom.
How do I know whether the lesson worked?
The exit ticket asks: “On your model, what does a blue winding ribbon stand for, and why does the model need a key?.” A river, and a key so somebody else can read it. A model with no key named means the reader point needs another run. That tells you whether the class needs a reteach or a thirty-second conversation before you plan tomorrow.
Is there a worksheet to go with Reading a Model of the Land?
Yes — 1 printable 2-ESS2-2 worksheet, linked at the end of the plan and free like the rest of the site. Each one comes with an answer key and 25 versions, so the practice after the lesson can be a different paper on every desk.
Is Reading a Model of the Land free to use?
Yes. The plan, its printables and their answer keys are free to read, print and photocopy for your own class, with no account and no email capture. It was last reviewed on 8 September 2026. Please do not resell it or republish it as your own.
