Sample Lessons
Go BlueBot Go!
Overview
Students will determine the distance of 1 unit of BlueBot. This will be helpful when using the BlueBot and for solving future challenges.
Concepts
 Estimation
 Distance
 Measurement
Materials Needed
 BlueBot
 String or other resource for measuring such as yarn or ribbon
 Marker
 Scissors
Activity
Place the BlueBot on the floor. Have a student place one end of string next to the front of the BlueBot. Another student may press the Forward arrow button once and then press Go. The BlueBot will move forward one unit. Mark the string where the front of the BlueBot stopped. Cut the string where marked. This represents the distance of one unit of BlueBot.
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 BlueBot to a designated location in the classroom. Try the program with the robot and see if you were correct, or if you underestimated or overestimated the distance.

Students will apply units of measurement to move the BlueBot to another location.

Materials Needed
 BlueBot
Activity
Have the students sit in a circle. One student begins by choosing another student sitting across the circle and then estimates how many units it will take BlueBot to reach the selected student. The student who goes first will estimate, test, and adjust if necessary. Once the BlueBot reaches the other student, have that student answer a question before selecting yet another student to program the BlueBot to reach. The teacher can ask a question that is general such as what is their favorite animal, movie or book. Or you can incorporate questions from current units of study.
Extension
 Addition problems: Write each student’s initial estimate on a chalkboard, dry erase board, or somewhere else 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 where you can add the additional units needed to reach the desired location. Place the BlueBot back where it began, enter the additional units and select Go. (BlueBot remembers the previous entry.) OR clear BlueBot’s memory by selecting the Clear (X) key, and then enter the new estimated total.
 Apply the same concept for subtraction. If the BlueBot goes too far students can use the back button to take away steps. Make sure you place the BlueBot back where it started.
Don’t forget that the BlueBot holds all previous commands entered. Unless the Clear (X) key is pressed, the BlueBot will include its previous commands, adding any new ones which you enter onto the end of the whole program. You can delete previous commands to start over with a fresh command sequence by selecting the Clear button (X).
