• Teach how to use “go to mouse-pointer” and “glide to random position” blocks.

5. Variable – Set Score and Change Score:

• Introduce the concept of scoring in games.
• Teach how to use variables to set and change scores.

Scratch Commands Covered:

• To Edit Costumes: Creating custom costumes for sprite variations.
• To Assign More Than 1 Condition to If: Using logical operators to combine conditions.
• Looks – Go to Front Layer: Managing sprite layering with the “go to front layer” block.
• Motion – Go to Mouse-Pointer, Glide to Random Position: Directing sprite movement towards a specific point.
• Variable – Set Score and Change Score: Tracking and updating scores using variables.

• Use the “glide to random position” block to place ladybugs.

7. Win Condition and End Game:

• Set up a win condition based on the player’s score.
• End the game with a win message and score display.

Conclusion:

• Recap the concepts learned: custom costumes, conditions, motion, variables, and looks blocks.
• Discuss the interactive and skill-based nature of Bug Beating gameplay.
• Emphasize the iterative process of testing and refining game mechanics.

Assessment:

• Assess understanding through questions during the lesson.
• Evaluate student projects based on the functioning Bug Beating game.
• Have students demonstrate their games and explain how they applied the concepts covered.

Allow students to experiment with ladybug behaviors, broom movement, and scoring systems to create an engaging and enjoyable Bug Beating game experience.
