The Five Major Oceans
![Picture](/uploads/1/7/0/9/17099422/3768558.jpg?504)
Grade Level: 2nd
Time: 40 minutes
Lesson Background:
In this lesson, I want students to be able to identify the five major oceans in the world on a map and then calculate the length of each ocean using a scale. This lesson is a great way to introduce map skills and get students to start thinking about the abstract idea of a scale.
Big Ideas, Key Concepts, Competencies: A map is a two dimensional description of a specific area of land. Maps describe in a visual or graphic format certain key features of the territory being examined. For example, a road map of the state of Montana shows many of the important state roads and how they interconnect. A roadmap might also show the towns and cities, as well as a few of the more popular destinations within a state. Other maps might show the distribution of birds along the wetlands of the Great Salt Lake, or the distribution of human populations throughout the world.Learning to use a map is a very important skill to learn. Maps help people locate everything and is the core of where directions come from. There are various types of maps: world maps, country maps, state maps, treasure maps, etc. Maps are important tools and are indispensable to geographers. They help geographers understand in a visual way important things about the surface of the Earth. Where do evergreens grow, where are volcanoes actively erupting, and where are trout most likely to be found, are all examples of how a geographer might use a map.
Teacher Knowledge:
Teachers should know that a map is small "picture" of a very large space. It is a guide to get you from one place to another especially one that you have not encountered before. On a map you will see a representation of distance, mountains, rivers, shapes of places or destinations, a compass, as well as a legend and scale. The teacher must know all basic components of a map: The first thing the teacher should be familiar with is that a map includes a compass rose that shows direction and that Cardinal Directions are the four base parts on a compass. Teachers should know what directions each Cardinal Direction points. The next thing teachers should know is that a scale is used to determine the distance of places on a map. Maps are scaled down so that they fit on the available paper or screen. When scaling down a map, every part of the map is scaled by the same amount. This insures that every object on the map is the same proportion as everything else on the map. If a city is twice as large as a neighboring town, an accurate scaled map will show the same relationship on paper. The drawn city will be twice as large as the drawn town.

Step-By-Step Procedure:
Engagement/Introduction
I will open up the lesson by having Google Maps projected on the screen, wall, or whiteboard. I will go to Google Maps and type in the school's address. I will begin asking questions. “What do you see here? Is this considered a map? What do we use maps for? What would we use this kind of map for?” I will write ideas on the whiteboard using a concept web. This help me evaluate their prior knowledge and will be able help me adjust the flow of the lesson based on the facts given by the students. I will then Google the Atlantic Ocean. I can zoom in and out to show students the different ways maps can look. This is a great way to add technology in the classroom instead looking at a typical paper map.
Explicit Instruction
“Today, we are going to look at maps and the things that we can find on maps. Whenever you look at a map, it is important to know where things are located. To help us determine the location and size of places and things, we look for a scale. A map makes distances look much shorter and smaller than they really are. Roads look only a few inches long on a map but they are really many miles long. A scale is a tool that we use with a ruler to help us calculate how big places are.
I will right these on the board and ask students to write the notes in their notebook:
First, you have to determine how many inches equal one mile (could be feet, miles, etc.). In this map, one inch equals 3,000 miles. Next, you measure how many inches two places are from one another with the ruler. The next step is adding the miles together. For example, if the distance was 3 inches, I would add 3,000 three times."
Modeling
I will then show students and think aloud many example of calculating miles with the scale and a ruler using the enlarged map and the directions I wrote on the board.
Guided Practice
When I determine they do not need any more explicit instruction, students will come up to the board and try for themselves. I will be there as a support as they are practicing and guide them if they struggle. This will give the teacher a chance to clarify any misconceptions students may have about using a map or a scale. Students will be instructed to calculate the WIDTH of each ocean using their individual maps. They will write their mileage in their notebooks for each ocean and will include all their math work (make sure to tell them that they are being graded on this page of their notebook, students can highlight steps or answers they are unsure of. As students are doing their assignment, I will play different sounds of water (links below): the ocean, rain, water drops, and rapids. For a wrap up activity, students will have write down their guesses of every sound. Write the four sounds and add two or three more on the board as a word bank.
Evaluation
The assessment for this lesson will be the final assignment where students are required to calculate the width of the five oceans. This is an assignment where I can assess student's work and determine what the student is having trouble with (map skill or math skill). I can also assess student progress with the topic by observing students during modeling and guided practice. An informal assessment can be taken place during the wrap-up when students guess the different sounds of water.

Differentiation
- Using a different map with small increments (instead of calculating miles by 3,000, they can find a smaller number)
- Calculating three ocean's widths instead of five
- Provide checklist with numbered directions that I wrote on the board
- Shorter, more chunked directions
