Social Studies
Objective: I can explain how a map and a globe are alike and different.
Standards: D2.Geo.1.3-5, D2.Geo.3.3-5
Builds on: Needs the United States map used in Week 2 and the idea that maps show places. One-minute check: your child points to land and to water on the world map (water is usually blue).
- globe – a round model of Earth
- continent – one of the seven largest pieces of land on Earth
- Day 11 — Maps and Globes — Big Question Warm-Up (5 min) — Spaced review from Week 2. Ask: "Name the three community types." (Urban, suburban and rural.) Then set the globe beside the flat map. Ask the big question: "Both show Earth. What is different?"
- Mini-Lesson (10–15 min) — Say: "A globe is a round model of Earth. It shows the true shapes and sizes of land and water." Say: "A map is a flat drawing of a place. It is easy to carry and can show a small place up close." Hold up the orange. Draw a simple shape on it with the marker. Peel the orange, keeping the peel in large pieces. Press the peel flat. Ask: "What happened to the peel?" (It tore or left gaps.) Say: "Earth is round too. To make a flat map, mapmakers must stretch some parts. On many maps, places near the poles look too big." Ask: "Which one has Earth's real shape?" (The globe.) Ask: "Which would you take on a hike? Why?" (A map. It folds and shows a small place.) If stuck, say: "Hold the ball. Can you lay it flat without tearing it?"
- Activity / Source Work (15–20 min) — 1) Your child finds each of these on the globe and then on the map. The seven continents: North America, South America, Europe, Asia, Africa, Australia and Antarctica. The Pacific Ocean and the Atlantic Ocean. The United States. 2) Keep a chart: Place | Found on globe | Found on map. Check each box. 3) Compare Greenland and Africa on the map, then on the globe. On many flat maps they look close in size. On the globe, Africa is about 14 times larger. Maps differ. If yours shows Greenland small, look at Antarctica instead. 4) Fill in a compare chart with four rows: shape, sizes, carrying, detail. Expect: round or flat; true or stretched; hard or easy to carry; whole Earth or one town up close.
- Notebook Entry (10 min) — In the notebook, your child draws a globe and a map side by side. Your child writes two facts under each. Then your child finishes: "I would use a map when ____ because ____." Sample: "I would use a map when I walk in a park because it shows the paths."
- Wrap-Up & Exit Ticket (5 min) — Ask the three exit questions aloud. Praise answers that explain why, using the orange peel or the globe.
Watch for: Believing the flat map shows true sizes, so Greenland seems as big as Africa.
Try: Find Greenland and Africa on the globe. Cover each with a fingertip to compare.
- Why can a flat map not show every place at its true size?
- Name one thing a map does better than a globe.
- On many flat maps, Antarctica looks like a long strip along the bottom. How could you check its real shape?
Answers: 1) Earth is round, and flattening it stretches some parts. 2) Answers vary. Look for: it folds, it is easy to carry, or it can show a small place up close. 3) Look at a globe. Antarctica is a rounded continent around the South Pole.
