Objective: I can find four major U.S. rivers on a map and explain why rivers matter to people.
Standards: D2.Geo.2.3-5, D2.Geo.8.3-5
Builds on: Needs Week 4: rivers are fresh water that flows. One-minute check: ask which keeps moving, a lake or a river (a river). Ask whether river water is salty or fresh (fresh).
- tributary – a smaller river that flows into a bigger river
Materials: U.S. map that shows rivers, laid flat, Blue yarn or string, about 3 feet, Scissors, 4 index cards, Glass of water, Dinner plate, Notebook, Pencil
- Warm-Up · 5 min
Spaced review from Week 4. Ask: "Name one landform that a river can carve." (A canyon or a valley.) Then hold up the glass of water. Ask: "Where does our faucet water come from?" (Many towns use rivers, lakes or wells.) Say: "Today we find out why big cities sit beside rivers."
- Mini-Lesson · 10–15 min
Tip the plate over a sink and pour a little water at the high edge. Say: "Water always runs downhill, from higher land to lower land. Rivers do the same." Trace the Mississippi on the map. Say: "The Mississippi River starts at Lake Itasca in Minnesota. It flows south about 2,300 miles to the Gulf of Mexico." Say: "A tributary is a smaller river that flows into a bigger one." Trace two. "The Missouri River starts in the Rocky Mountains and joins the Mississippi near St. Louis. The Ohio River starts at Pittsburgh and joins it at the southern tip of Illinois." Trace the Colorado. "In the West, the Colorado River carved the Grand Canyon over millions of years." Say: "Rivers give people water, a road for boats, and rich soil for farms." Ask: "Which way does the Mississippi flow?" (South.) "Name its two big tributaries." (Missouri and Ohio.) If stuck, say: "Put your finger where the river starts. Slide toward the sea."
- Activity / Source Work · 15–20 min
Yarn rivers and a river town. 1) With scissors, cut one long piece of yarn and three short pieces. 2) Your child lays the long piece along the Mississippi, from Minnesota to the Gulf. 3) Add the Missouri and the Ohio so each joins the Mississippi. Add the Colorado in the Southwest. 4) Label four index cards, each with a river and a place beside it. Mississippi: New Orleans. Missouri: Kansas City. Ohio: Cincinnati. Colorado: Grand Canyon. Your child sets each card by its river. 5) Read this source aloud: "St. Louis began as a trading post near the place where the Missouri meets the Mississippi. Boats could reach it from the north, the south and the west. Traders brought furs and farmers brought grain to its docks. Riverboats carried those goods down to New Orleans. By 1850 it was one of the ten largest cities in the country." 6) Ask: "Find two pieces of evidence that rivers helped St. Louis grow." (Boats reached it from three directions. Steamboats carried goods to New Orleans.)
- Notebook Entry · 10 min
Your child sketches the four rivers on a rough United States outline. An arrow on each shows which way it flows. Then finish two frames. "Rivers help people by ___, ___ and ___." (Giving water, carrying boats and goods, leaving rich soil.) "The Missouri is a tributary because ___." (It flows into a bigger river, the Mississippi.)
- Exit Ticket · 5 min
Read each question aloud. Your child answers in the notebook and shows each river on the map. Praise answers that use the word tributary.
Watch for: Thinking every river flows south, or "down the page" on a map.
Try: Trace the Ohio flowing southwest and the Missouri flowing southeast. Say: "Rivers follow the slope of the land, not the top of the map."
- What is a tributary?
- Which river begins at Pittsburgh and flows into the Mississippi?
- Why does the water in a river keep moving?
Show answers
- A smaller river that flows into a bigger river.
- The Ohio River.
- Water runs downhill, from higher land to lower land.
Support: Write each river's name on a small paper scrap and set it on the map first. Your child then only lays the yarn where each river flows.
Extend: Your child finds the river closest to home on a map and writes where it starts and ends.
Homework: Your child asks a family member where your home's drinking water comes from and writes one sentence. Look for a named river, lake, reservoir or well.
