?Essential question

How do suspense and earned payoff shape a reader's experience?

Students will be able to
  • Plan and write an interactive story with clear setting, character, and problem
  • Use Boolean variables and if/else logic to control page navigation
  • Apply descriptive language and tone to enhance narration
  • Build interactive scenes using backgrounds, characters, and buttons
  • Debug and revise based on feedback and testing

Assessment
Formative
Use milestone checks, organizer responses, and daily test evidence to guide feedback.
Summative
The opening, clue, search, discovery, and ending form one causal story, and the final treasure changes something meaningful. The key click sets the state, locked navigation respects that state, return buttons work, and the success page appears only after discovery.
The student journey

From reading to an interactive project

Elementari is a browser-based tool for creating illustrated, interactive stories and projects. Students plan their writing in the Student Kit, then add it to a digital project in the editor, called Studio.

📖

Read

The reading provides background knowledge or a model of writing for students to draw on. The lesson plan explains its connection to the project.

📖Twenty-Two Days at a Sealed Door

On the fourth of November, 1922, in Egypt's Valley of the Kings, a workman's tool scraped something flat under the sand: a stone step. Then another. Howard Carter had been digging in that valley for years, season after season, and had found…

Write & plan

Students use the Student Kit's storyboard to plan and draft their project. Choose High Support, Guided Support, or Independent to adjust the writing scaffolds.

Student mission

Design a treasure-hunt story where the chest stays locked until your reader earns the key.

Publish

The payoff

Students finish and test their projects. Work submitted through a class goes to the teacher for review; publishing a project makes it public with a shareable link.

Prep before class

A couple of things to gather, a few quick steps to prep — then you're ready to hand it to students.

What you need
  • One device per student or pair
  • Internet connection
  • Student Kit or printed organizer
  • Writing Organizer
  • Coding Cheat Sheet
  • Peer Review
  • Single Point Rubric
  • A device per student or pair
Prep before class
  1. 1Preview the designated builder story.
  2. 2Review the ordered milestones and Student Kit.
  3. 3Decide whether students work independently or in pairs.

What you need to know

Key terms

Watch for these misconceptions
✕
The READER is told to find an item that is invisible, unhinted, or unrelated to the lock. → Add a clue and make the key visually discoverable before increasing difficulty.
✕
The ending opens without the key or stays locked after the key is found. → Show the Boolean value during testing and test false and true conditions separately.

Differentiation & accessibility

Choose the writing support

These are the three support options in the Student Kit. Choose the scaffolds students need while keeping the same project.

High Support

More writing scaffolds
  • Sentence frames break the response into manageable parts
  • Supplied words and ideas help students get started
  • Students still have space to write their responses

Guided Support

A starting point for writing
  • Task prompts and selected sentence starters
  • Writing cues and word banks where supplied
  • Space to develop each response

Independent

Less scaffolding
  • The same project and required writing tasks
  • Open response space without the support frames
  • Students develop their own wording

Questions

Teacher FAQ

Do I — or my students — need to know how to code?

No prior coding knowledge is required to start. Students follow on-screen build steps in Studio. Coding difficulty describes the project's complexity; teachers may still need to help students test and revise. The lesson plan supports teaching, and the Answer Key provides sample writing responses.

How long does this lesson take?

About 130, paced into 45-minute class periods. You can spread it out or compress it — students pick up where they left off, so it doesn't have to finish in one sitting.

What devices does this lesson work on?

Use a Chromebook, laptop, desktop or tablet with a modern browser and an internet connection. The project editor does not support phones. Try the build on your class devices before teaching.

What is Studio Compass?

Studio Compass is the step-by-step guide inside the Studio. It shows students what to do next, identifies the exact coding blocks they need, and confirms completed milestones so they can keep moving independently.

How does this lesson support different learners?

The Student Kit has High Support, Guided Support and Independent writing profiles. They change the amount of scaffolding for the same project. Choose a profile in the kit before printing, and use the lesson plan's differentiation suggestions.
