Teacher's Notes: Move a specific distance forward Pro Preview

Clearly designate the starting position

If the floor is tiled, use a few tiles. If the floor has lines, use a few lines. Always mark the starting and the final lines for reference.

Students will forget where the start and the end exactly are, and you, as a teacher, must mark the start and end on the floor.

Manage students to take turns

Use one testing area per 10-12 students and teach them to respect a waiting line. 

Choose the distance and when the task is solved

Choose a distance on your own. Any distance will work well, especially if it has a meaning. A distance with a meaning is a student's height: "Move as far with the robot as the height of a student." 

Be strict with the task

You must decide what range of distances near the end marker counts as enough to solve the task. Is 5 cm near the end marker an acceptable solution? Is 10 cm acceptable? Is 2 cm acceptable?
Decide that and teach your students precision and that you have your criteria for a successfully solved challenge.

Also, make sure you encourage your students to try again and again.
