**Number Line**

View a larger version of the mat.

This colorful mat is a long strip of numbers from zero to ten, with the appropriate number of animals in each box. Students can move Bee-Bot forward and back along the number line to reach target numbers.

This mat is a perfect way to introduce Bee-Bot to your youngest students. They don’t need to turn the ‘bot, just move it in a straight line from number to number.

When they use Bee-Bot or Blue-Bot, be sure they understand that they should:

• **Always** press **X** before their turn to erase the commands from the previous student.

• **Always** let the ‘bot finish its instructions without touching it, unless it is going to fall off a table or run into an obstacle.

• **Always** press **Go** again to stop Bee-Bot when it is moving or just pick it up when it is going to fall off a table or run into an obstacle.

• **Never** push or turn the ‘bot when it is moving, as that could harm its motor.

The math concepts involved in using this mat include:

• counting

• matching

• simple addition and subtraction

Social skills include:

• taking turns

• working in a group

• helping others who may need support

**Lesson Ideas**

Although these ideas refer to Bee-Bot, they can all be done with Blue-Bot as well.

Remind students to press **X** to erase the commands the previous student entered.

**Lesson Idea 1: Going to a Specific Number**

- Divide students into groups.
- The teacher calls out a number.
- One of the students navigates Bee-Bot forward or backward to that number and counts the number of animals for that number out loud.
- The student places Bee-Bot back to zero.
- Repeat, with all students having a turn.

**Lesson Idea 2: Going to a Random Number**

- Each student in a group rolls dice or picks a playing card from a deck at random.
- The student then gives Bee-Bot commands to go to that number.
- The student places Bee-Bot back to zero.
- Students take turns navigating Bee-Bot to the number they picked.
- This idea is similar to the first one, but does not require teacher interaction.
- Students need to determine what to do if the number rolled is too high (twelve for the dice).

**Lesson Idea 3: Counting to Reach a Target Number**

In this lesson, students use counting to determine how many steps Bee-Bot should take to get to a target number.

- The teacher tells the first student in the group to go to one of the animals.
- The student counts the number of steps forward or backward to get there and instructs Bee-Bot to go that many steps.
- Without moving Bee-Bot, the next student navigates Bee-Bot to the box with the next animal the teacher names.
- Continue so that all students have had several turns.

For example, with Bee-Bot on the zero box:

- Student 1 goes to the turtles. Forward 7 steps, then Go.
- Student 2 goes to the sheep. Back 5, then Go.
- Student 3 goes to the bees. Forward 8 steps, then Go.

**Lesson Idea 4: Using the Online Number Line Mat**

If students are using computers in your classroom, have them use the online Number Line Mat in the Bee-Bot Emulator in a browser. They can use dice or playing cards to choose how far to move Bee-Bot.

**Lesson Idea 5: Exploring Addition and Subtraction**

- Two students choose a number from 0 to 10.
- The first student navigates Bee-Bot to their number.
- The second student navigates Bee-Bot to their number.

Ask students to consider the two numbers chosen.

If Bee-Bot goes in a straight line, the two numbers are added together. What is their sum?

If Bee-Bot goes forward and then back, the second number is subtracted from the first. What is the difference?

**Mat Details**

This mat is incorporated into several of the *Bee-Bot Lessons*. These lessons give teachers lesson plans that are tied to national curriculum standards. They give students an opportunity to engage in over 180 learning activities using the floor Bee-Bot or Blue-Bot or the same activities in the online emulator.

The mat is made of washable vinyl and measures approximately 13” by 74” (30 cm by 165 cm)
