Lesson:

Clear the Board

In this coding challenge, students will work together (from a safe distance) with an army of whiteboard robots to clear a magnetic whiteboard of all dry-erase marks.

With the Class

  1. Allow your students to remotely connect to the robots on the board.
    1. If you have more students than robots, students can take turns connecting and disconnecting with the Roots, all remotely, in between rounds.
  2. Challenge students to work as a team to code Root to wipe the entire board clear of all dry erase marks using its robot eraser.
    1. TIP: You can find the Eraser Code Block by editing the Marker Block
  3. Play multiple rounds with your classroom! After some practice, how quickly can they clear the board?
Educational Standards

CSTA K-12 CS Standards

1A-AP-08

Model daily processes by creating and following algorithms (sets of step-by-step instructions) to complete tasks.

1A-AP-09

Model the way programs store and manipulate data by using numbers or other symbols to represent information.

1A-AP-10

Develop programs with sequences and simple loops, to express ideas or address a problem.

1A-AP-11

Decompose (break down) the steps needed to solve a problem into a precise sequence of instructions.

1A-AP-14

Debug (identify and fix) errors in an algorithm or program that includes sequences and simple loops.

1B-AP-10

Create programs that include sequences, events, loops, and conditionals.

1B-AP-11

Decompose (break down) problems into smaller, manageable subproblems to facilitate the program development process.

1B-AP-15

Test and debug (identify and fix errors) a program or algorithm to ensure it runs as intended.

2-AP-15

Seek and incorporate feedback from team members and users to refine a solution that meets user needs.

Next Generation Science Standards

K-2-ETS1-1

Ask questions, make observations, and gather information about a situation people want to change to define a simple problem that can be solved through the development of a new or improved object or tool.

3-5--ETS1-1

Define a simple design problem reflecting a need or a want that includes specified criteria for success and constraints on materials, time, or cost.

MS-ETS1-1

Define the criteria and constraints of a design problem with sufficient precision to ensure a successful solution, taking into account relevant scientific principles and potential impacts on people and the natural environment that may limit possible solutions.

MS-ETS1-2

Evaluate competing design solutions using a systematic process to determine how well they meet the criteria and constraints of the problem.
