Review color codes with class. While not necessary, it is helpful if students have prior knowledge of how these bots work and function using color codes. Review what happens when Evo reads certain codes and the correct way to color the boxes so Evo can read the codes.

Hand out one Thankful Pumpkin page per student. Lead a class discussion on why people celebrate a holiday about gratitude and thankfulness. Ask leading questions such as: Why do you think it is important to be thankful? What are you thankful for? Have students choose four things they are thankful for and write them in the blank spaces on the Thankful Pumpkin page.

Have students plan which codes they would like to use on their pumpkin. Encourage students to use multiple different codes. If necessary, give students a minimum number of codes they must use, such as “Your pumpkin must have at least five different codes.”

Have students use markers to add color codes to their pumpkin and draw black lines over the outlined portion of the pumpkin for the Evo to follow. Remind students the Evo needs thick black lines to navigate the pumpkin properly.

Have students share their finished pumpkin with a neighbor. Have students explain why they chose certain codes and what they expect their Evo to do.

Hand out Evos, and have students use them on their pumpkins. If students are sharing Evos, have students switch the Evo back and forth every few minutes.
