Social Studies
Objective: I can use a map key, the compass rose, and a scale without help.
Standards: D2.Geo.2.3-5, D2.Geo.3.3-5
Builds on: Needs the Week 3 lessons on map keys, directions and scale. One-minute check: ask, "What do we call the map symbol that shows north, south, east and west?" (A compass rose.)
- Day 21 — Flex: Reteach Map Skills — Big Question Warm-Up (5 min) — Before you start, draw the Pine County map on the plain paper. Put a compass rose in a corner with N at the top. Write the scale: 1 inch = 10 miles. Draw a house in the middle for Home. Draw a book 3 inches east of Home and a tree 1 inch north. Draw a blue crayon oval 4 inches west and a barn 2 inches south. Add a key: book is library, tree is park, blue oval is lake, barn is farm. Spaced review from Week 3. "Which way is east on this map?" (Right.) "What does the book stand for?" (Library.) "How far is 2 inches on this scale?" (20 miles.) Today's big question: "Could you read this map with no help at all?"
- Mini-Lesson (10–15 min) — Reteach directions and the key. Write N, S, E and W on the sticky notes. Stick each on the matching wall. The sun rises in the east, so use that to choose. Say: "North is at the top of most maps. East is on the right. South is at the bottom. West is on the left." Your child points to each wall as you name it. Say: "Before I look for anything, I read the key. Where is the park? The key says the tree is the park. I see the tree. It is above Home, so the park is north of Home." Ask: "What does the barn stand for?" (The farm.) "What direction is the farm from Home?" (South.) "What direction is Home from the lake?" (East.) If stuck, say: "Put your finger on the starting place. Which way does it move to reach the other place?"
- Activity / Source Work (15–20 min) — Scale work. 1) Show the ruler. Find the zero line and mark it with a pencil dot. 2) Say: "Zero goes on the middle of the first symbol." 3) Your child measures from Home to each place. 4) Your child fills in a chart with three columns: Place, Inches, Real miles. 5) Your child counts by tens for each inch. Expect these results. Park: 1 inch, 10 miles. Farm: 2 inches, 20 miles. Library: 3 inches, 30 miles. Lake: 4 inches, 40 miles. 6) Change the scale. Say: "Now let 1 inch = 20 miles. Count by twenties." Ask: "How far is the farm now?" (40 miles: 20, 40.) 7) Ask one two-step question. "You drive from the park to Home, then on to the farm. How far?" (30 miles.) If a measure is a little off, round to the nearest inch.
- Notebook Entry (10 min) — In the notebook, your child writes My Map Rules with one example each. "1. Read the key first. 2. North is at the top. 3. Each inch on the scale stands for ____ miles." Sample example: "The tree means park. The park is north of Home. The park is 10 miles away."
- Wrap-Up & Exit Ticket (5 min) — Read the three exit questions aloud. Your child may use the ruler but not your help. If one is missed, repeat that step in tomorrow's warm-up. Praise answers that include a direction word or the word miles.
Watch for: Reading the scale correctly but measuring from the end of the ruler instead of the zero line.
Try: Mark the zero line with a dot. Your child lines it up three times before measuring anything.
- A map has north at the top. The pool is drawn to the left of the school. What direction is the pool from the school?
- Why must the zero line of the ruler sit on the first place you measure from?
- A scale says 1 inch = 20 miles. A road on the map is 3 inches long. How long is the real road?
Answers: 1) West. 2) So the measurement starts in the right spot. If it does not, the distance comes out wrong. 3) 60 miles. Count by twenties: 20, 40, 60.
