Earth Day 2022 …

Apr 11, 2022

Earth Day is April 22! Celebrate with Dash, Dot, and Cue!

Carrie Willis (@carriewillis18) and her elementary students at Valley Preparatory School in Redlands, CA, found a way to celebrate Earth Day with their entire school community — that included Dash! As part of a school-wide recycling initiative, the students at Valley Prep were able to use prior knowledge about recycling and coding to help Dash make good choices when disposing of waste on campus.

“The students love robots, so including Dash and Dot is the perfect way to engage students in the lesson, and help to reinforce important curriculum topics, while also teaching important coding and computer science skills.” — Carrie Willis, Technology Director

First, Mrs. Willis gathered some simple materials:

  • one Dash robot
  • one gridded mat
  • cups of varying sizes
  • 4 trash can labels: Paper & Cardboard, Plastic, Aluminum, Compost
  • various images representing paper, cardboard, plastics, aluminum and compost items
Mrs. Willis found a recycling activity sticker kit from the Dollar Tree but these images could be replicated using colored paper and clip art or student drawings.

Mrs. Willis laid out a gridded mat as the challenge space, to help with measurements (see our article on how to create a DIY gridded mat). She attached the four trash can labels to the larger cups and placed them upside down in a row at the end of the mat. Then she added a recyclable’s image on each of the smaller cups. These smaller cups, representing cardboard boxes, plastic containers, banana peels, etc., were scattered around the mat.

The challenge was for students to program Dash to collect and sort the recyclables. The students had to first move Dash to one of the smaller cups and position the robot behind the cup. Then to deliver the item to the appropriate recycle bin, Dash had to push the cup in the right direction without moving past the bin.

Mrs. Willis reinforced the coding fundamentals of sequences and loops, plus underscored the notion of growth mindset with good ol’ trial and error. Cheers were abound when Dash was successful!

“Robots are fun to use in real-world scenarios, because robots are relevant to the time that we live in. People in the 21st century use robots for nearly everything, and for students to learn how to program is giving us a head start to the future.” — Kate Donez, 6th grade student

Here are some other Earth Day activity ideas for Dash, Dot, and Cue:

  • Celebrate Earth’s 4.5 billionth birthday (give or take a few years) with a song and dance routine.
  • Compose an original melody for Mother Earth on Xylo.
  • Traverse a map of the globe and pre-record Dash to tell scientific fun facts about the biomes or regions.
  • Use the bulldozer attachment to clear a field or create an original attachment to pick up “litter.”
  • Write poems in honor of Earth Day and have Dash or Cue recite the rhymes.
  • Toss seeds into furrows (well, balls into cups) with Launcher.
  • Dress up the CleverBots as your favorite Earth inhabitants using the Building Brick Connectors.
  • Navigate Dash through an imaginary habitat, while avoiding the endangered species (played by Dot).

Wonder League Robotics Competition FAQ | Year 8

Hello, robotics enthusiasts! If you’re here, you’re probably as excited as we are about the 8th Annual Wonder League Robotics Competition! To help you and your teams have the best possible experience competing this year, we wanted to share answers to some Frequently Asked Questions (FAQ).

Who Can Compete:

Any kid, anywhere in the world, ages 6-8 (Innovator Cup) and 9-12 (Pioneer Cup). There are two age brackets: 6-8 and 9-12 and team members have to fall within the age category at some point during the competition. Participants must be the qualifying age for their bracket on the last day of the competition, but if they gain a year during the competition, that’s OK. They won’t age out! 

Competition Brackets:

  • Innovator Cup (Age 6-8)
  • Pioneer Cup (Age 9-12)

What Makes a Team:

A team is made up of a supervising adult coach, and one or more children (up to 5). That’s right, kids can compete solo, but a coach who is 18+ is needed to help with the submission process. For multi-kid teams, each member must be in the same age bracket. Coaches may have multiple teams and can register all their teams after registering as a coach. Please keep in mind that each team will need a separate Class Connect registration.

Note: Younger students may participate in the 9-12 age category, but please be aware that the missions have been designed with older students and advanced coding skills in mind.

What a Team Needs to Compete:

Class Connect subscription

The team is made up of a supervising adult coach and one to five members

  1. Compatible device
  2. 5′ x 8′ mat of 30cm squares and basic prototyping materials
  3. Teams in 6-8 & 9-12 age brackets will need a Dash robot
  4. Internet access to download and upload materials

Teams will need one Dash robot:

Check Device Compatibility here:

We will be offering a mat image that you are welcome to use and print with your local printer, but teams are absolutely encouraged to make their own if they prefer. For more on how to make your own mat, check out this blog post.

Coaches will, of course, need internet access to download the apps and keep up with the competition as it progresses, and may want to print out some kid-facing materials that we will provide at each stage.

Class Connect Subscription:

To register for the 8th Wonder League Robotics Competition requires a subscription to Class Connect, providing additional resources like standards-aligned content assignable right inside a student’s Blockly app. Learn more about Class Connect here.

If you already have a Class Connect subscription, you have access to register a team, based on your student license amount. If you have more than one team of 5 students, you will need to purchase another Coach Success Pack or consider a larger subscription to accommodate more teams and students.

  1. A Coach Success Pack provides:
    Participation in the WLRC for up to 5 students
    Access to all Missions
    Full access to Class Connect, (including Math Activities and Dash’s Neighborhood), for 5 students and 1 teacher for 7 months
    A discount code for a Dash robot from our online store at

Please note: Teams will need a physical Dash robot to complete the Missions.
The Coaches’ Dashboard in Class Connect will help our coaches register and manage their team(s). The dashboard will be your one-stop shop for all Wonder League Robotics Competition management. You will be able to access the Coaches’ Corner–where all competition-related content and resources will be hosted–the Heartbeat community forum, and all the submission forms right there on the Dashboard.

Accessing Missions for the Innovator Cup and Pioneer Cup:

Once your purchase is completed for Class Connect, you will receive an email to activate your Class Connect license.

Once this license is activated, you will be able to register yourself as a coach and register your teams. This is done on your portal page under the Robotics Competition tab.

Once your team/teams are registered, you will get an additional email from CoAssemble, our partner hosting the missions this year. This email will state you have been registered for the “2022-2023 Coaches Corner Course”.

Click on the link to be redirected to the CoAssemble website, and you will see the course and can access the Coaches’ Corner Guide as well as the Missions (available November 3, 2022).

Still having trouble accessing all the resources in the Coaches’ Corner? If you have previously had a license to Class Connect and registered as a coach, and have not seen Coaches’ Corner added to your CoAssemble list of courses, please email us at, and we will provide assistance.

Last Year’s Missions:

Taking a peek at last year’s missions might help you get a sense of what the competition is like. Just sign in with your Class Connect subscription and register as a coach to take a peek at the previous years by going to the Coaches’ Corner and selecting the desired year.

The WLRC People’s Choice Award allows teams to share and celebrate their work in the WLRC and encourage community support in voting for their team. This is an optional category for teams to enter and will not impact scoring of the Invitational Round submission as they will be judged by STEM and Coding experts using a published rubric.

Children’s Privacy:

We take our participants’ privacy very seriously and comply with COPPA when collecting any information. In the invitational round we ask only for the students’ first names, and request parents’ permission. For those that make it into the Invitational Round, we ask for full names, again with permission. We are never marketing, selling to, or corresponding with children. All contact is through the proxy of the coach.
