Warm-Up

• Draw a rough outline of a square on a piece of paper.
• Ask students to draw four small squares inside the square, making sure they are evenly spaced.
• Ask students to label each square with a number (1-4).
• Have students draw a line from square 1 to square 2 and from square 2 to square 3.
• Ask students to label the lines with numbers (1-2, 2-3).
• Have students draw a line from square 3 to square 4 and from square 4 to square 1.
• Ask students to label the lines with numbers (3-4, 4-1).
• Ask students to draw a line from square 1 to square 4 and from square 3 to square 2.
• Ask students to label the lines with numbers (1-4, 3-2).
• Ask students to draw a line from square 2 to square 1 and from square 4 to square 3.
• Ask students to label the lines with numbers (2-1, 4-3).
• Ask students to draw a line from square 3 to square 1 and from square 4 to square 2.
• Ask students to label the lines with numbers (3-1, 4-2).
• Have students count the number of lines they drew and record it on their paper.
• Ask students if they noticed any patterns in the numbers they used to label the lines.

Direct Instruction

• Introduce the concept of a point as a unique location in space that is defined by a set of coordinates (x,y).
• Show students how to write the coordinates of a point on a coordinate grid using the x- and y-axes.
• Explain how lines are created by connecting two or more points.
• Show students how to use the x- and y-axes to find the coordinates of the points that make up a line.
• Explain how planes are created by intersecting two or more lines.
• Show students how to use the x- and y-axes to find the coordinates of the points that make up a plane.

Guided Practice

• Provide students with several sets of coordinate grids and ask them to identify the points, lines, and planes that are created.
• Have students work in small groups to identify the points, lines, and planes in the coordinate grids.
• As a class, discuss the examples and explain how they were able to identify the points, lines, and planes.

Independent Practice

• Have students work on a project-based activity where they have to create points, lines, and planes using the coordinate grids.
• Students can use the grid to create a shape, pattern, or design using the coordinate numbers.
• Encourage students to be creative and think outside the box as they work on their projects.

Closure

• Ask students to share their point, line, and plane creations with the class.
• Have students reflect on the creative and challenging nature of the project-based activity.

Assessment and Evaluation

• Observe students during the guided and independent practice activities to assess their progress in naming points, lines, and planes in symbols.
• Collect and review their point, line, and plane drawings to assess their understanding of the concepts.
