Representing Land and Water on Maps

Active learning helps second graders grasp abstract geographic concepts by making them concrete. When students move, discuss, and create, they connect symbols on maps to real places in ways that passive instruction cannot. Building and interpreting representations builds spatial thinking skills that are critical for future geography lessons.

Activity 01

• Think-Pair-Share
• 20 min · Pairs

Think-Pair-Share: Map vs. Globe

Show students the same region on a flat map and on a globe. Ask: what do you notice is the same? What is different? Partners discuss for two minutes before sharing with the class. Use student observations to introduce the concept that flat maps distort shape or size to represent a round planet.

Explain how maps and globes represent Earth's surface.

Facilitation Tip

For the Think-Pair-Share, provide each pair with a globe and a flat map so they can physically compare shapes and sizes as they talk.

What to look for

Provide students with a simple world map. Ask them to label one continent, one ocean, and draw a symbol for a city. Then, ask them to write one sentence explaining what the color blue usually represents on a map.

Gallery Walk: Map Symbol Decoding

Post six to eight oversized map legends around the room, each from a different type of map (physical, political, weather, road). Students rotate with a recording sheet, writing what each symbol or color means. Reconvene to compare findings and discuss how different maps serve different purposes.

Differentiate between land and water features on a map.

Facilitation Tip

During the Gallery Walk, post one map type per station and give students a simple decoding sheet with color and symbol definitions to carry with them.

What to look for

Display a physical map with clear landforms and water bodies. Ask students to point to and name three different landforms and two different bodies of water. Ask: 'How do you know that is water?'

Map Making: Our Classroom Continent

Students draw a simple map of the classroom (or school building) using a top-down perspective, create their own legend with at least three symbols, and include a title and compass rose. Sharing maps in pairs and navigating to a 'destination' the partner marks reinforces that maps communicate spatial information to a reader.

Analyze how symbols and colors are used to convey information on maps.

Facilitation Tip

In the Map Making activity, model how to simplify classroom features into basic shapes before students begin drawing their own maps.

What to look for

Show students a flat map of the world and a globe. Ask: 'What differences do you notice between the map and the globe? How does the shape of the Earth affect how it looks on a flat map? What might be left out or look different on the flat map?'

A few notes on teaching this unit

Teach this topic through repeated exposure to the same conventions across different formats. Avoid rushing to correct misconceptions; instead, let students discover them through hands-on tasks and peer discussion. Research shows that spatial reasoning improves when students manipulate materials and articulate their thinking to others.

Students will confidently identify and explain symbols for land and water on maps and globes. They will use agreed-upon conventions to create their own simple maps and justify their choices. Conversations and artifacts will show growing comfort with the idea that maps are models, not exact replicas.

Watch Out for These Misconceptions

• During the Think-Pair-Share activity, watch for students who describe the map as an exact photograph of Earth seen from space.

  Pause the discussion and ask each pair to trace their finger along a coastline on the globe and then on the flat map. Prompt them to notice how the shape changes and why.

• During the Gallery Walk activity, watch for students who assume all maps show the same information about land and water.

  At each station, ask students to read the map title and legend aloud, then write one thing they learned that isn't shown on the other maps they visited.
