Objective

By the end of this lesson, you will be able to apply geometric concepts to create and analyze a game.

Materials and Prep

• Pencil and paper
• Ruler
• Protractor

Prior knowledge of basic geometric concepts such as angles, lines, and shapes is required.

Activities

1. Designing Game Board:

   Start by drawing a rectangular game board on a piece of paper. Use your ruler to ensure straight edges. Label each corner of the board with a letter, such as A, B, C, and D.

2. Creating Game Pieces:

   Using different shapes (circle, triangle, square, etc.), draw game pieces on separate pieces of paper. Cut them out and label them with corresponding letters.

3. Defining Game Rules:

   Decide on rules for your game. For example, you can create a rule that a player can only move their game piece along a straight line between two corners of the game board. Or you can create a rule that a player must rotate their game piece by a certain angle before making a move.

4. Playing and Analyzing the Game:

   Play the game with a friend or family member. Keep track of the moves made and the strategies used. After the game, discuss the geometric concepts involved, such as angles formed by the game pieces and lines on the board.

Eighth Grade Talking Points

• "Geometry is a branch of mathematics that deals with shapes, sizes, and properties of figures."
• "Angles are formed when two lines meet. They can be classified as acute, obtuse, or right angles."
• "Lines can be straight or curved. They can intersect, be parallel, or perpendicular to each other."
• "Shapes can be classified into different categories such as polygons (triangles, quadrilaterals) and circles."
• "In our game, we are using geometric concepts to create a game board and game pieces."
• "We can analyze the game by looking at the angles formed by the game pieces and the lines on the board."
• "By understanding geometry, we can apply mathematical thinking to create and analyze games."
