Use controlled motor movements, sensors and organised programs to solve a practice competition challenge in the shortest amount of time.
- Read through the pupil material in the LEGO® Education SPIKE™ App.
- Plan accordingly, this project is designed to be completed over multiple classes.
- In order to complete this lesson, your pupils will have to have built the Advanced Driving Base model and the Dozer Blade and Lift Arm tools.
2. Engage (10 Min.)
- Use the ideas in the ‘Ignite a Discussion’ section below to engage your pupils in a discussion relating to this lesson.
- Use the video to explain the lesson.
3. Explore (30 Min.)
- Have your pupils work in pairs to build the Game Module, Path and Field Marker models.
- Ask them to work together to write a program for their Advanced Driving Base that solves the competition challenge. Remind them to use everything that they've learned up until now.
4. Explain (10 Min.)
- Facilitate a discussion about the importance of planning each step of a program. Discuss the use of pseudocode and My Blocks to help in the planning.
5. Elaborate (40 Min.)
- Allow your pupils to continue to work on their solutions until they're ready for a timed trial.
- Remind them to start by writing pseudocode.
- Don't forget to leave some time for tidying up.
- Give feedback on each pupil's performance.
- In order to simplify the process, you can use the assessment rubrics that have been provided.
Ignite a Discussion
Use these questions to engage your pupils in a discussion about how they can use what they've already learned to successfully solve this challenge:
- What is decomposition of a problem?
- How will you use this skill to help complete this challenge?
- What skills have you learned over the previous lessons that will help you to successfully complete this mission?
Have your pupils watch this video to see what they're about to do.
Example Game Context
Use this theme or create your own:
- The farmer has gone on holiday and needs help programming his robotic farmhand to collect the eggs without breaking them.
- Advanced Driving Base with tools
- Game Module combined with the Path model
- 2 Markers
- 4 Crates
- 6 Penalty Bricks
Mission 1: Unlock the gate
Program the Advanced Driving Base to push in the actuator to unlock the Game Module gate.
Mission 2: Open the gate
Program the Advanced Driving Base to push down on the latch to open the Game Module gate.
Mission 3: Pass the marker
Navigate the field and pass at least one Marker without touching it.
Mission 4: Follow the path and collect the Crates
Guide the Advanced Driving Base towards the Game Module and collect the Crates.
Mission 5: Safely deliver the Crates
Deliver the Crates to the outside of the two markers.
- Unlocking the gate (10 pts)
- Opening the gate (10 pts)
- Passing the Marker (10 pts)
- Following the Path and collecting the Crates - collect at least 2 Crates (10 pts per crate); 10 bonus pts if all four crates are collected
- Safe delivery of one or more Crates 50 cm away from the hen to finish (20 pts)
Brick Penalties (Optional)
- Collisions with Markers when carrying Crates
- Any instance of picking up, removing or re-placing the robot
A maximum of six penalty bricks can be given.
Each penalty brick will result in a deduction of 5 points from the final score.
Your pupils will create their own programs for this project. Remind them to use some of the concepts that have been covered in this unit:
- Variable Block
- Loop Block
Simplify this lesson by:
- Solving one part of the mission as a group with your pupils
Take this lesson to the next level by:
- Incorporating the optional brick penalties into the game
- Challenging your pupils to complete all of the missions as quickly as possible and with no penalties
- Changing the field setup and inventing new rules
- Adding lines to the table in order to add complexity to the challenge
Teacher Observation Checklist
Establish a scale that suits your needs, for example:
- Partially accomplished
- Fully accomplished
Use the following success criteria to evaluate your pupils' progress:
- The pupils worked well as a team to complete one mission.
- The pupils worked together as a team to complete all of the missions.
- The pupils are able to present their robot, program and mission strategy, explaining how they've successfully completed each mission.
Have each pupil choose the brick that they feel best represents their performance.
- Blue: I've successfully completed one mission.
- Yellow: I've successfully completed all of the missions.
- Violet: Along with my team, I've presented our robot, program and mission strategy to our coach with each team member participating.
Encourage your pupils to provide feedback to one another by:
- Having one pupil use the coloured brick scale above to score another pupil’s performance
- Asking them to present constructive feedback to one another so that they can improve their group’s performance during the next lesson
Language Arts Extension
To incorporate the development of language arts skills:
- Have your pupils prepare and deliver a presentation about how they developed an effective strategy for completing the challenge in the shortest amount of time.
Note: This will require additional time.
