What is one distance of Blue-Bot?
Overview : Students will determine the distance of 1 unit of Blue-Bot. This will be helpful when using the Blue-Bot and solving future challenges.

Concepts
• Estimation
• Distance
• Measurement

Materials Needed

• Blue-Bot
• String or other resource for measuring such as yarn or ribbon.
• Marker
• Scissors

Activity
Place the Blue-Bot on the floor. Have a student or students place one end of string next to the front of the Blue-Bot. Have a student select the forward arrow one time and then go.* The Blue-Bot will move forward 1 unit. Mark the string where the front of the Blue-Bot stopped. Cut the String where marked. This represents the distance of one unit of Blue-Bot.

Extension

• Have students create a name for the unit of measurement.
• Compare the string to a ruler and see how many inches/centimeters one unit of Blue- Bot represents.
• Estimate how many units it will take to move Blue-Bot to a designated location in the classroom. Try it and see if you were right, need more, or less.
Getting to Know You
Overview: Students will apply units of measurement to move the Blue-Bot to another location

Concepts
• Estimation
• Distance
• Measurement
• Direction

Materials Needed

• Blue-Bot

Activity

Have students sit in a circle. One student picks another student sitting in the circle and estimates how many units it will take Blue-Bot to reach the selected student. The Student will estimate, test, and adjust if necessary. Once the Blue-Bot reaches the student, have that student answer a question before selecting another student to send the Blue-Bot to. Perhaps introducing themselves if it is the beginning of the school year, their favorite something, a book they recently read they would recommend, their are infinite ways you can incorporate questions from current units of study..

Extension

• Addition problems: Write the students initial estimate on a chalkboard,dry erase board, somewhere where all can see. For example if a student estimates forward 5 write 5. If the estimate is too short put a plus sign next to the 5, creating an addition problem and “add” the additional units need to reach the desired location. Place the Blue-Bot back where it began, Enter the additional units and select Go. (Blue-Bot remembers the previous entry) OR Clear Blue-Bots memory by selecting the Clear (x) key and enter the new estimated total.
• Apply the same concept for subtraction, if the Blue-Bot goes to far students can use the back button to take away steps. Make sure you place the Blue-Bot back where it started.

Don’t forget the Blue-Bot holds all previous commands entered, and adds new ones onto the end. You can delete previous commands by selecting the clear button.
