SPIKE™ Essential

Literary Randomizer

How can Daniel’s literary randomizer make picking a book more exciting?

30-45 min.
Grades 3-5


  • Review the Literary Randomizer lesson in the LEGO® Education SPIKE App.
  • If necessary, pre-teach these related vocabulary words: genre, overwhelmed, randomizer, and success.
  • Consider the abilities and backgrounds of all your students. Differentiate the lesson to make it accessible to everyone. See the Differentiation section below for suggestions.
  • If time allows, plan and facilitate the language arts extension. See the Extension section below for more information.


(Whole Class, 5 Minutes)

  • Facilitate a quick discussion about making decisions.
    • Talk with your students about when they had to make a big decision.
    • Ask questions, like: What criteria did you use to make the decision? How did you evaluate whether you were happy with your decision?
  • Introduce your students to the story’s main characters and the first challenge: programming the literary randomizer to pick a book.
  • Distribute a brick set and a device to each group.


(Small Groups, 30 Minutes)

  • Have your students use the LEGO® Education SPIKE App to guide them through their first challenge:
    • Create and test the program that picks the book genre.
  • Have your students iterate and test their models to complete the next two challenges in the app:
    • Modify the program to improve how the literary randomizer works.
    • Design your own upgraded literary randomizer.
  • You can find coding and building support in the Tips section below.


(Whole Class, 5 Minutes)

  • Gather your students together to reflect on their completed challenges.
  • Ask questions, like: What was Daniel’s problem? How did you help solve it? How did you improve Daniel’s literary randomizer? Why did you decide to improve that?


(Whole Class, 5 Minutes)

  • Prompt your students to discuss and reflect on the process of setting success criteria to determine whether a solution was successful.
  • Ask questions, like: Why is it important to set success criteria and understand what makes a solution successful? How do success criteria help you to improve something you've created?
  • Have your students clean up their workstations.


(Ongoing Throughout the Lesson)

  • Ask guiding questions to encourage your students to “think aloud” and explain their thought processes and reasoning in the decisions they've made while building and programming.

Observation Checklist

  • Measure your students’ proficiency in defining success criteria to evaluate a solution.
  • Create a scale that matches your needs. For example:
    1. Needs additional support
    2. Can work independently
    3. Can teach others


  • Have each student choose the brick that they feel best represents their performance.
    • Yellow: I think I can define the success criteria for evaluating a solution.
    • Blue: I can define the success criteria for evaluating a solution.
    • Green: I can define the success criteria for evaluating a solution, and I can help a friend do it too.


  • In their small groups, have your students discuss their experiences working together.
  • Encourage them to use statements like these:
    • I liked it when you…
    • I'd like to hear more about how you…


Coding Tip

  • After your students complete their first challenge, they'll be provided with three Inspiration Coding Blocks to help them modify their programs.
  • The Inspiration Coding Blocks are intended to spark their imaginations as they experiment to find their own solutions.

Model Tip

  • After your students complete their second challenge, they’ll be provided with three Inspiration Images and an open-ended prompt for improving their models.
  • The Inspiration Images are to help spark their imaginations as they experiment and personalize their models.

There aren't any building instructions for this challenge.


Simplify this lesson by:

  • Selecting one Inspiration Image to help your students personalize their models
  • Experimenting with either the coding or the building

Increase the difficulty by:

  • Changing how the literary randomizer is constructed
  • Exploring new and different coding blocks in the program


  • Have your students write stories based on the genre chosen by their literary randomizers. Make sure that they use narrative techniques, such as dialogue and description, to create a story that fits the genre.

If facilitated, this will extend beyond the 45-minute lesson.
