Finding Function Values on a Graph for 3rd Grade
A guided-notes packet of about two pages that introduces f(x) as the y-value on a graph, using an apple-stand pricing example with a table and coordinate grid. It builds skills in reading coordinate graphs, connecting x-values to y-values, and interpreting function notation, and it is designed for a whole-class lesson or independent note-taking during a 30-minute math block.
“guided notes for students to use f(x) and find y on a graph”
Teacher Guide & Tips
- Use this as a guided-notes handout during a whole-class mini-lesson: read the Key Idea aloud, then have students fill in the blanks as you trace points on the graph with your finger.
- Discussion question: If the apples cost $2 per pound, what would f(3) mean in the real world, and where would you find it on the graph?
- Scaffold for struggling readers: Provide a sentence frame such as "When x is ___, the y-value is ___," and have students circle the x-axis and y-axis labels before reading the example.
- Extension for advanced students: Ask them to predict f(5) from the pattern in the table, then check their prediction on the graph and explain why the line y = 2x makes that value true.
- Estimated time: About 30 minutes including the example walkthrough and two or three practice points.
