Weather Bars

This is lesson 7 of 10 in the unit "The Wonders of Weather and Water". Lesson Title: Graphing Weather Patterns: Creating and Analyzing Bar Graphs Lesson Description: I can organize my collected weather data into a bar graph and identify patterns in the data. Students will transfer data from their weather logs onto a bar graph, label axes, choose appropriate titles, and participate in a class discussion about what the graphs reveal about local weather trends. Key concepts include data representation, bar graph construction, pattern recognition, and making predictions based on data. Success Criteria: Create a correctly labeled bar graph from one week of temperature data and identify at least one pattern or trend observed in the data. Differentiation: Provide pre-formatted graph templates with labeled axes for dyslexic and ELL students; use large-grid graph paper for students with fine motor challenges; offer a digital graphing tool option for students with ADHD; support students with Down syndrome using a simplified pictograph format with teacher guidance. Extension: Analyze the patterns in your graph and write or present a prediction for what the weather might look like the following week, explaining your reasoning.

Overview

In this lesson, students organize one week of temperature data into a bar graph and then analyze the graph to find patterns. This builds toward later unit tasks by strengthening data representation and “how many more/less” reasoning.

Learning intentions

Students will be able to:

transfer collected temperature data into a correctly scaled bar graph
label axes with an appropriate scale and units
choose a clear title that matches the data set
identify one or more patterns or trends shown in their bar graphs

Success criteria

I can make a bar graph with correctly labeled axes and bars that match my data values.
I can use a consistent scale so classmates can read the graph accurately.
I can describe at least one pattern or trend I notice in temperatures across the week.
I can use graph information to answer a “how many more” or “how many less” question.

Curriculum links

Measurement and Data: draw and interpret scaled bar graphs using several categories and solve “how many more/how many less” problems.
Measurement and Data: represent data clearly on graphs to support comparison and pattern finding.

Lesson structure (45 minutes)

0–5 min · Warm-up & Review. Teacher reviews what temperature categories mean (days of the week) and asks students to recall: “What makes a bar graph easier to read than a list?” Students share quick ideas, then name the axis they remember (x-axis for categories, y-axis for measurement).
5–12 min · Model a Bar Graph. Teacher projects or draws a partially completed bar graph for a sample (e.g., Monday–Sunday temperatures) and models: choosing a scale, labeling axes, adding bars, and writing a title. Students chorally read the axis labels and answer: “What does each bar represent?” and “How do we know the height?”
12–25 min · Build Your Graph (Hands-on). Teacher distributes one-week temperature logs and graph paper/templates. Students create their own bar graphs using their data, including a title and labeled axes. Students transfer data day-by-day into bars, using the same scale across the y-axis, then check that their bars reach the correct heights.
25–34 min · Quick Conferencing & Fix-it Time. Teacher circulates with a checklist (scale consistent? axes labeled? title present? bars match values?). Students revise one part if needed (e.g., adjust a bar height, rewrite axis labels, add missing title).
34–42 min · Pattern Share (Class Discussion). Teacher prompts discussion using sentence frames: “I notice that ___ is highest/lowest,” “The temperatures ___ over the week,” and “My prediction is ___ because ___.” Students share in pairs, then the class collects 2–3 common patterns (e.g., rising, dropping, a midweek peak).
42–45 min · Exit Ticket. Teacher gives a short “how many more/less” question tied to student graphs (or a teacher-made example graph) and one pattern question. Students answer independently and submit.

Resources

One-week temperature logs from Lesson 6
Large-grid graph paper (optional) and standard graph paper
Pre-formatted bar graph templates with labeled axes (for targeted supports)
Colored pencils/markers
Class chart paper/whiteboard and marker
Digital graphing tool option (tablet/computer) for students who prefer it
Teacher checklist for quick conferences
Exit ticket slips

Assessment

Formative: during circulation, check axis labels, scale consistency, and whether bars match the data values
Formative: listen for accurate pattern statements during pair and class discussion
Summative/quick check: exit ticket on (1) one “how many more/how many less” comparison and (2) one observed pattern

Differentiation

Dyslexia and reading support: provide printed, high-contrast templates with short directions; offer an audio-recorded version of the steps; use a “Read + Do” model (teacher reads template prompts, then students do)
ELL support: use sentence frames for pattern statements and model vocabulary with visuals (temperature, axis, scale, higher, lower, bar)
Fine motor support: provide large-grid graph paper and allow use of straightedge/stencils for bar edges; allow tracing templates for axis labels
ADHD support: offer a digital graphing option (instant placement and clear visuals) and provide a two-stage checklist (“Fill data → Build bars”)
Down syndrome support: provide simplified pictograph-style teacher-guided option (teacher helps convert temperature counts into a simplified display) and use fewer categories (e.g., group days into “week early” vs “week late” if needed) with teacher conferencing
Check for understanding: after modeling, do a 30-second “thumb check” for scale choice before students begin copying

Extension (optional for advanced learners)

Write or present a prediction for next week’s temperatures using evidence from the pattern in the bar graph, and explain reasoning (e.g., “Because the bars increase toward Friday, I predict…”).
