Saxon Math Lesson Plan 17: Sorting by Color and Creating a Real Graph
Grade Level: Kindergarten
Duration: 30 Minutes
Subject: Mathematics
Topic: Sorting by Color and Comparing Sets of Objects
Objectives:
By the end of this lesson, students will be able to:
- Sort objects by color.
- Create a simple bar graph using the sorted objects.
- Compare two sets of objects based on their quantities.
Materials Needed:
- A variety of colored objects (e.g., blocks, buttons, crayons)
- Chart paper or a large whiteboard
- Markers in different colors
- Graph paper (optional)
- Scissors (for the teacher's use)
- Glue (for the teacher's use)
Standards:
This lesson aligns with the following Common Core State Standards for Mathematics:
- K.MD.A.1: Describe measurable attributes of objects, such as length or weight.
- K.MD.B.3: Classify objects into given categories; count the number of objects in each category.
Procedure:
Introduction (5 minutes)
- Begin the lesson by asking students if they can name different colors.
- Show examples of the colored objects and let them explore by holding and examining a few.
- Explain that today they'll be sorting these objects by color.
Guided Practice (10 minutes)
- Invite students to join you in a circle.
- Place a mixed selection of colored objects in the center.
- Demonstrate how to sort objects by color, selecting one color at a time, and encourage students to help with the sorting.
- As you sort the objects, ask questions like:
- "How many red objects do we have?"
- "Can anyone find a yellow object?"
Creating a Real Graph (10 minutes)
- Once the objects are sorted, take the chart paper or whiteboard.
- Draw a simple bar graph with one bar for each color.
- Label the axes: the x-axis for "Colors" and the y-axis for "Number of Objects."
- Use the sorted objects to fill in the bars by counting and coloring them with the marker corresponding to each sorted object.
- Discuss the graph with the students, asking questions like:
- "Which color has the most objects?"
- "Is there a color that has none?"
Independent Learning (5 minutes)
- Provide each student with a small number of colored objects.
- Ask them to sort their objects by color on their desks.
- After sorting, they can share how many of each color they have with a partner or a small group.
Conclusion (5 minutes)
- Gather the class back together and discuss what they learned about sorting and counting.
- Reinforce the importance of color recognition and the concept of bar graphs with open-ended questions:
- "What do you like about sorting?"
- "Can you think of other things we can sort?"
Assessment:
- Observe students during the sorting activity to ensure they understand how to sort by color.
- Evaluate their understanding through participation in the bar graph activity.
- Informal assessment will occur through their responses during group discussions.
Extensions:
- For advanced students, introduce the concept of sorting by two attributes, such as color and size.
- For students needing more support, provide additional one-on-one assistance during the sorting activity.
Reflection:
- After the lesson, reflect on what went well and what could be improved. Consider student engagement and understanding of the concepts taught.
This lesson plan provides a structured approach to learning about sorting by color and graphing, suitable for Kindergarten students while adhering to US educational standards.
