Lesson Plan: Saxon Math Lesson 22 - Placing an Object on a Real Graph
Objective
Students will be able to understand the concept of graphing objects on a two-dimensional graph. They will learn how to identify axes, understand coordinates, and place objects correctly on a graph.
Grade Level
Reception / Kindergarten
Duration
30 minutes
Materials Needed
- Large graph paper or a whiteboard with grid lines
- Sticky notes
- Markers or crayons
- Real object for demonstration (e.g., a toy or a book)
Common Core Standards
- K.MD.A.1: Describe measurable attributes of objects, such as length or weight.
- K.G.A.2: Correctly name shapes regardless of their orientations or overall size.
Lesson Outline
Introduction (5 minutes)
- Begin the lesson by asking students if they have ever seen a graph, explaining that graphs are used to show information in a visual way.
- Show a large graph (on graph paper or whiteboard) and briefly explain the x-axis (horizontal) and y-axis (vertical).
Direct Instruction (10 minutes)
- Explain the concept of graphing:
- Introduce the idea of coordinates (the two numbers we use to find a point on the graph).
- For example, if you say, "Place your sticky note at (2,3)," the first number tells you how far to go on the x-axis and the second number tells you how far to go on the y-axis.
- Demonstrate by placing a sticky note on the graph at coordinate (2,3).
- Use real objects as examples. For instance, "If we place the toy car at point (1, 2), we move 1 space along the x-axis and 2 spaces up on the y-axis."
Guided Practice (10 minutes)
- Distribute sticky notes and markers to each student.
- Call out coordinates (e.g., (1, 1), (2, 2), (3, 3)) one at a time.
- Instruct students to place their sticky notes on the graph in the correct location as you call out the coordinates.
- Walk around and provide assistance as needed, encouraging students to identify which direction to move (right for x-axis, up for y-axis).
Independent Practice (5 minutes)
- Ask students to create their own coordinates using their sticky notes and place their objects on the graph in pairs.
- Each pair will call out the location of their objects to the class, reinforcing their understanding of coordinates.
Closure (5 minutes)
- Gather students and discuss what they learned today about placing objects on a graph.
- Ask questions such as, "What did you find easy?" or "What was the hardest part?"
- Reinforce that graphs can be used to show where things are found or how we can organize information.
Assessment
- Observe students during both guided and independent practice to assess understanding.
- Check if students can accurately identify and place objects on the graph based on the coordinates given.
Extensions
- For advanced students, you may introduce simple bar graphs. Use snacks (like fruit pieces) to create visual representations based on students' preferences.
- Plan a follow-up lesson to introduce more complicated graphing concepts with objects of different sizes and shapes.
This lesson plan aims to engage young learners in a fun and interactive way to understand basic graphing concepts, showcasing the importance of spatial relationships in mathematics.
