RI.1.7
Use the illustrations and details in a text to describe its key ideas.
Objective
Students will be able to state a key idea of an information text and support it with a detail from the words and a detail from a diagram.
Students are successful when they can
- States the key idea: "Each part of a plant has a job."
- Gives a detail from the words: "The roots drink water."
- Gives a detail from the diagram: "The label shows the stem in the middle, joining roots and leaves."
What you need
- The "Parts of a Plant" text and a large labeled diagram (both in the Teach section)
- A real plant, such as a pot of herbs or a weed pulled up with its roots
- The printable practice sheet linked at the end of this plan
The lesson
Warm-up — what is this diagram for?
5 min- Show the diagram without the text: a plant with labels and arrows for roots, stem, leaves and flower.
- Ask: "What is this picture for? Why does it have words and arrows?" Fish for "to show the names of the parts."
- Say: "This kind of picture is a diagram. Its labels teach us things."
Teach — the idea, and two kinds of support
13 min- Read: "A plant has parts, and each part has a job. The roots hold the plant in the soil and drink up water. The stem carries the water up to the leaves. The leaves use sunlight to make food for the plant. The flower makes seeds so new plants can grow."
- Ask: "What is the big idea?" Fish for "Each part of a plant has a job." Write it in a box at the top.
- Ask for support from the words: "The roots drink water." Write it under the box with a W.
- Ask for support from the diagram: point to the label "stem" and the arrow from the roots to the leaves. Say: "The diagram shows where the stem is, in the middle, joining the roots to the leaves. Now I can see how water can get up." Write it with a P.
- Hold up the real plant. Point to each part and ask its job. The diagram and the real plant match.
- Say: "The words told us the jobs. The diagram showed us where each part is. Together they explain the big idea."
“A key idea needs proof. Give me one proof from the words and one from the picture.”
Guided practice — idea plus two
12 min- Give pairs a new text and diagram: "A bird's body helps it fly. Its wings flap to lift it up. Its feathers are light. Its tail helps it steer." The diagram labels beak, wing, feathers, tail and feet.
- Pairs write the key idea in a box and add one W detail and one P detail.
- Then they explain to another pair how the diagram helped them understand the words.
- Circulate and ask "Which label helped you?" A good answer: "The tail label showed it is at the back, so it can steer like a boat's rudder."
- Share one box with two details and check each detail matches the idea.
“Your two details must both prove the same idea. Read the idea, then read each detail — do they match?”
Independent practice
8 min- Students complete the illustrations page, reading the text and answering what the pictures and labels show.
- Remind them to look at the labels on every diagram.
- Ask finishers to draw and label a simple diagram for one of the texts.
Close
2 min- Point to the leaves on the diagram. Ask: "What is their job, and how do you know?"
- Fish for: "They make food — the words told us."
What goes wrong, and why
Each of these is a reasoning error rather than carelessness. The fix addresses the reasoning.
Names the labels as the key idea: "The idea is roots, stem, leaves."
Why: The labels are big and clear, so they seem like the most important thing. Naming the parts feels like understanding them.
Fix: Ask "What does the text tell us about those parts?" A key idea says something; a list just names things. Say "Each part ___" and let them finish it.
Gives two details from the words and none from the diagram.
Why: They trust words more than pictures for facts, so the diagram is skipped.
Fix: Cover the words and ask "What can you learn from just the diagram?" Point to an arrow or label and ask what it shows. Then add it as the P detail.
Gives a detail that does not support the idea: "Plants are green."
Why: It is true and it is about plants, so it feels like a good detail.
Fix: Read the key idea, then the detail: "Each part has a job... plants are green." Ask "Does that tell us about a job?" Help them choose a detail that does.
If they are not there yet
- Give the key idea and ask only for the two details.
- Use a diagram with only two labels, roots and leaves.
- Let the child point to the diagram detail and say it, instead of writing.
If they finish early
- Add one more label to the plant diagram (seed or soil) and write its job.
- Explain how the arrow in the diagram helps you understand the stem's job better than the words alone.
- Find a diagram in a class book and write its key idea with one W and one P detail.
Exit ticket
State one key idea from the plant text. Give one detail from the words and one from the diagram.
What to look for: "Each part has a job," "Roots drink water" (words), "The stem joins roots and leaves" (diagram). A list of labels as the idea means they need the "Each part ___" frame. Two word details means they need to look at the diagram on its own.

Questions about Illustrations and the Key Ideas
How long does the Illustrations and the Key Ideas lesson take?
40 minutes, split across 5 timed sections: warm-up 5 min, teach 13 min, guided practice 12 min, independent practice 8 min, close 2 min. The minutes are stated per section and add up to the stated length, so the plan can be cut or extended at a section boundary rather than abandoned halfway.
Which standard does Illustrations and the Key Ideas teach?
CCSS.ELA-LITERACY.RI.1.7 — RI.1.7, Reading: Informational Text for Grade 1: “Use the illustrations and details in a text to describe its key ideas.” In plain terms, use the pictures and details together to explain the main ideas.
What do I need to teach this lesson?
The "Parts of a Plant" text and a large labeled diagram (both in the Teach section), a real plant, such as a pot of herbs or a weed pulled up with its roots and the printable practice sheet linked at the end of this plan. Everything listed is either ordinary classroom equipment or a free printable from this site — there is nothing to buy and nothing to prepare beyond photocopying.
What mistakes should I expect in this lesson?
Three, each a reasoning error rather than carelessness: names the labels as the key idea: "The idea is roots, stem, leaves."; gives two details from the words and none from the diagram and gives a detail that does not support the idea: "Plants are green.". The plan gives the thinking behind each one and the teaching move that addresses the thinking rather than the symptom.
How do I know whether the lesson worked?
The exit ticket asks: “State one key idea from the plant text. Give one detail from the words and one from the diagram.” "Each part has a job," "Roots drink water" (words), "The stem joins roots and leaves" (diagram). A list of labels as the idea means they need the "Each part ___" frame. Two word details means they need to look at the diagram on its own. That tells you whether the class needs a reteach or a thirty-second conversation before you plan tomorrow.
Is there a worksheet to go with Illustrations and the Key Ideas?
Yes — 1 printable RI.1.7 worksheet, linked at the end of the plan and free like the rest of the site. Each one comes with an answer key and 25 versions, so the practice after the lesson can be a different paper on every desk.
Is Illustrations and the Key Ideas free to use?
Yes. The plan, its printables and their answer keys are free to read, print and photocopy for your own class, with no account and no email capture. It was last reviewed on October 8, 2026. Please do not resell it or republish it as your own.
