# Introductory Lessons

## Lesson 1: What is One Distance of Bee-Bot?

### Overview

Students will determine the distance of 1 unit of Bee-Bot. This will be helpful when using the Bee-Bot and solving future challenges.

### Concepts

- Estimation
- Distance
- Measurement

### Materials Needed

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

### Activity

Place the Bee-Bot on the floor.

- Have a student place one end of string next to the front of the Bee-Bot.
- Have a student press the forward arrow one time and then
**Go**. - The Bee-Bot will move forward 1 unit.
- Mark the string where the front of the Bee-Bot stopped.
- Cut the String where marked. This represents the distance of one unit of Bee-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 Bee- Bot represents.
- Estimate how many units it will take to move Bee-Bot to a designated location in the classroom. Try it and see if you were right, need more, or less.

## Lesson 2: Getting to Know You

### Overview

Students will apply units of measurement to move the Bee-Bot to another location.

### Concepts

- Estimation
- Distance
- Measurement
- Direction

### Materials Needed

- Bee-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 Bee-Bot to reach the selected student.
- The student will estimate, test, and adjust if necessary.
- Once the Bee-Bot reaches the student, have that student answer a question before selecting another student to send the Bee-Bot to. They could perhaps introduce themselves if it is the beginning of the school year, their favorite activity, a book they recently read they would recommend, etc. There are infinite ways you can incorporate questions from current units of study.

### Extension

**Addition problems:**Write the student’s 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 Bee-Bot back where it began, Enter the additional units and select Go. (Bee-Bot remembers the previous entry) OR Clear Bee-Bots memory by selecting the Clear (x) key and enter the new estimated total.**Subtraction problems:**Apply the same concept for subtraction. If the Bee-Bot goes too far, students can use the back button to take away steps. Make sure you place the Bee-Bot back where it started.

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