3rd Grade Comparing Data with Subtraction

3rd Grade Comparing Data with Subtraction Worksheet (Analyzing Data, TEKS 3.2C)

Students use real Austin, Texas temperature data and subtraction to find how much warmer or cooler one month is than another, then compare the size of two changes. Simple black and white doodles and big, easy to read text keep the focus on the thinking, not the reading. No prior knowledge is needed: the page teaches the idea first.

What's Inside

• A teach strip with a worked subtraction example
• Part A: subtract to compare monthly temperatures, with a worked example
• Part B: compare two changes and find the warmest to coolest difference
• A friendly squirrel guide that points out the key idea
• A visual answer key with answers marked in red, plus a short teacher note

How Teachers Use It

Use it as a mini lesson follow up, a quick check, or a science center. It takes 6 to 8 minutes and prints clearly in black and white. The focus skill is using mathematical calculations to compare patterns, part of the grade 3 scientific and engineering practices.

Why It Works

Each sheet teaches one idea first, then asks students to use only what the page taught. Every activity has a done for you example, and students only circle, sort, or write a letter, so they can finish on their own. Wrong choices are believable, not silly, so students have to think. Pair it with the other Analyzing Data sheets to cover models, patterns, unusual data, sources of error, evidence, math comparisons, and design criteria.
