Measuring Rain Data

Overview

Today students measure a simple form of rainfall data and write an informative/explanatory chart-based entry. The lesson builds toward writing clearly organized information with facts and details, using illustrations when helpful.

Learning intentions

Students will be able to:

• Introduce a weather topic and what they measured.
• Record rainfall measurements in an organized chart.
• Develop their topic with facts and details about the rainfall amounts.
• Include an illustration or diagram that helps a reader understand the data.

Success criteria

• I can measure rainfall using a consistent method and unit.
• I can record my rainfall data in a clear chart (with labeled columns).
• I can write a short informative paragraph using facts from my chart.
• I can add a simple illustration (bar graph or drawing of the rain amounts) to help my reader.

Curriculum links

• Writing (informative/explanatory): Introduce a topic and group related information; include illustrations when useful.
• Writing (informative/explanatory): Develop the topic with facts, definitions, and details.
• Writing: Write informative/explanatory texts to examine a topic and convey ideas clearly.
• Writing (process skills): Use selected, organized, and analyzed content accurately to explain information.

Lesson structure (60 minutes)

1. 0–8 min · Warm-up & model. Teacher briefly reviews the unit question: “How can we measure weather in a fair way?” Teacher shows an example “Rainfall Chart” with labeled columns (date, amount, unit). Students repeat key labels and tell what the chart is used for.

2. 8–18 min · Direct teach: measurement method. Teacher explains a simple, consistent measuring plan (one method for everyone): place a flat container/catch cup outside or near a window, collect for a set time, then pour/measure the collected water in a small measuring cup or use marked cups/strips. Students practice reading the measurement lines and say the unit aloud (e.g., milliliters or inches).

3. 18–30 min · Measure (active data collection). Teacher starts the collection window (or uses “already collected” sample water if real-time rain isn’t available) and reminds students to keep the method the same. Students measure carefully, record the number, and confirm the unit in the chart.

4. 30–42 min · Chart writing (organized information). Teacher demonstrates how to “group related information together” by filling out the chart from top to bottom and labeling it clearly. Students complete their chart entry and add one quick visual (a simple bar/dot representation or a drawing showing “more/less” accurately).

5. 42–52 min · Write an informative paragraph. Teacher provides a three-sentence planning frame:

• Sentence 1: Topic + what you measured.
• Sentence 2: Fact from your chart (the amount and unit).
• Sentence 3: Detail that explains the result (how it was measured and what the amount means). Students write their paragraph using their chart facts and include their illustration as a support near the writing.

6. 52–58 min · Conferencing & revision check. Teacher asks two quick questions: “What is your topic sentence?” and “What fact from the chart did you include?” Students revise by correcting one detail (spelling of unit, number accuracy, or chart label).

7. 58–60 min · Exit ticket (quick assessment). Teacher asks: “Show me your chart amount and point to the sentence where you used that fact.” Students answer and teacher notes one strength + one next step.

Resources

• Rainfall measurement setup (catch cup or flat container)
• Small measuring cup with clear markings (inches and/or milliliters)
• Chart template with labeled columns (Date, Amount, Unit)
• Pencil, clipboard/paper for recording
• Example filled chart and sample paragraph on paper
• Simple drawing supplies (crayons/markers) for illustration/bar representation
• Timer for the collection window (if doing real collection)

Assessment

• During measurement: teacher listens for correct unit and careful recording.
• During charting: teacher checks labels, clear grouping, and accurate numbers.
• During writing: teacher reviews whether the paragraph introduces the topic and includes facts/details from the chart.
• Exit ticket: student points to the chart fact used in the paragraph.

Differentiation

• Support (speech delay needs): provide sentence frames with word banks (Unit, Date, Amount, Measured with…). Allow pointing and single-word responses before full sentences.
• Support (measurement confidence): pre-marked cups/strips or “choose-the-right-number” options to reduce counting errors.
• Advanced learner extension within the same task: add a second data point (another day or another small sample) and require two facts in the paragraph (compare more/less and by how much).
• Reduced load option: if writing is difficult, student writes 2 sentences plus labels on the chart and adds a labeled illustration.

Extension (optional, for advanced learners)

• Students predict future rainfall using past data: teacher prompts, “If yesterday was X and today was Y, what might happen next and why?” Student adds one prediction sentence to their paragraph using “I think” + reason from their chart trend.
