Use the instructional video to guide your students through the Introduction to Color Codes activity. Alternatively, continue with the direct instructions below.

Explain to students that they will learn to program the Ozobot to travel left, right, or straight in today's lesson. Show page 1 and place the bot at start. Ask students to watch where their bot ends up. Repeat this several times as students try to figure out how the bot makes decisions when it comes to an intersection. Explain to students that Ozobot makes random decisions at intersections, but can be programmed to turn left, right, or continue straight.

Explain that Ozobot's language has Color Codes that program it to turn left, turn right, or travel straight at an intersection. Show students that they can always find these Color Codes on the Color Code reference sheet.

Display Page 2 and use Color Codes to program Ozobot to reach the end, avoiding the lines that end in red. Point out that the Direction code is before the intersection, so Ozobot knows which way you'd like it to go before it actually reaches the intersection.

Model how to turn the paper so that your body is facing the same direction that my bot will be traveling. Explain that you can more easily determine that my bot must turn right. Show how to draw the "Right at Intersection" Color Code. Then, place Ozobot on Start and ask students to watch and see if the bot reaches the end of the line.

Display Page 3 and guide students to complete their activity sheet. Explain that Ozobot should eat pancakes, go to the beach, put on sunglasses, and then play with the dog. Model how to turn the paper so that you are facing the same direction as the bot will be traveling. Explain that it helps with directionality, and prevents you from getting confused.

Model the first activity. Since Ozobot would like to eat pancakes, explain that Ozobot needs to turn right at the intersection. Draw the "Right at Intersection" Color Code in the blank, then put Ozobot on Start to see if it makes it to the pancakes. Instruct students to complete the rest of the worksheet independently.

Display Page 4 and explain to students that they will explore Ozobot's Line Switch codes. Explain that Line Switch codes tell your bot to go off the line and find another one. Point out the Start and End areas, and explain that Ozobot needs to be programmed to line switch in a particular direction. Ask students if the bot should line switch right, left, or straight.

Explain that the gap between the end of the line and the new line is closest if the bot travels straight. Model how to draw the Color Code for "Line Switch Straight" in the boxes. Place Ozobot on Start to test the code.

Explain that when Ozobot finds the new line, it randomly chooses which way to go. Sometimes, it'll choose right, and travel straight to the end point. Sometimes, it might choose to turn left. Point out the U-Turn Color Code and explain that it allows the bot to turn around and make it to the end.

Wrap up the lesson by reviewing what students have learned so far:

• Drawing a line for Ozobot to follow
• Drawing Color Codes to tell Ozobot to do something
• Programming Ozobot to travel in specific directions at intersections
