[With Prompt] "Why not have a mini-lesson at home?" How to make home learning for elementary school students a little more fun using Gemini and NotebookLM.

"Home learning for children" is something I find quite difficult.

Even when parents try to explain things, they worry about how to put it so the child understands.

Furthermore, even if you go to the trouble of explaining it,
if it isn't connected to the child's interests, it doesn't really sink in.

In other words, what's hard about home learning isn't just "solving problems,"
but perhaps the stage before that: "creating the desire to learn."

That's why I thought it would be useful to use
Gemini's Gems and NotebookLM to create customized learning materials for each child
.

For example,

• If the child likes soccer, compare math to soccer

• If the child likes dinosaurs, compare science to the world of dinosaurs

• If the child likes games, learn like leveling up

• If the child likes dogs, have a Shiba Inu teacher explain it

By doing this, simple slides
become like a "mini-lesson just for that child."

Turning them into slides has the following benefits:

• You can separate the content page by page

• It's easier for children to look at

• Easier for parents to explain

• Easier to include quizzes along the way

• Easier to save for review

In particular, for younger children, reading long sentences can be a burden in itself.

This time, I have summarized how to create learning materials that focus on "creating a desire to learn" using Gemini and NotebookLM!

The creation process

The workflow for creating them is simple.

1. Input photos of worksheets or the theme you want to learn into a Gemini Gem

2. The Gem creates an explanation text for children

3. Put that explanation text into NotebookLM

4. Generate slides with NotebookLM

1. Input a photo of a worksheet or a topic you want to learn into a Gemini Gem

Upload this image or input the topic you want to learn into the Gem.

2. Answer just three questions, and the Gem will create an explanation for the child

It will return questions like this.

This time, I answered like this.

Then, the explanation text below will appear!

The point is that it doesn't just create an explanation.
With this system, you can set the following:

• Target grade level

• Teacher character

• Things the child likes or is good at

• Gentle language

• Quiz format

• Questions that make the child think

With just this, a simple slide becomes a slightly more fun mini-lesson.

3. Put the explanatory text generated by Gem into NotebookLM

Next, we will create slides.
Ultimately, we will upload the character and the text from earlier like this ↓.
When generating slides, check only the two items you want to use
and uncheck the others.

If you have reference images for the character, use those as well.

Regarding the character,
I generated and uploaded an image of the "otter"
character sheet that I entered into Gem.

4. Generate slides with NotebookLM

The explanatory text created by Gem can be used as-is for reading.

However, for elementary school home learning,
slides are sometimes easier to follow than just text.

Enter the text into the custom instructions and generate the slides.

Format: Detailed slides
Length: Default

I felt that selecting these options works better.

With this, all that's left is to wait for the slides to be generated, and you're done!!

あなたは小学生向けの楽しくてわかりやすい学習教材を作成する専属のAI先生です。

このタスクは、以下の【Step 1】から【Step 2】まで順番に、確実にステップを踏んで実行してください。ユーザーからの回答を待たずに、勝手に次のステップへ進まないでください。

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
【Step 1】ヒアリング（初回起動時）
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

起動直後、まずは挨拶をし、最高品質の教材を作るために以下の3点について教えてもらうよう質問してください。

1. 対象学年（例：小学3年生、小学6年生 など）

2. 先生役のキャラクターの設定
   ※ユーザーから特に指定がない場合は、AI側で毎回ランダムにキャラクター
   （例：物知りなフクロウ、元気な犬、ロボットなど）を1つ決定し、
   それに合った性格や語尾で進行してください。

3. 興味のある分野や好きなもの
   ※解説の例え話に使用します。

※上記3つの回答と、「学びたい内容のテキスト」または「教科書の画像」を受け取ったら【Step 2】へ進んでください。

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
【Step 2】教材の生成
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

ユーザーから指定された「学年」「キャラクター設定」「興味のある分野」に基づき、提出された学習内容に沿って対話形式の教材を生成します。

◆キャラクター設定の適用

* 指定された設定、またはAIがランダムに決定したキャラクターの特徴や独自の語尾を、すべてのセリフに徹底して反映させてください。
* 先生役として、読者（小学生）に対して直接、親しみやすく語りかけます。
* 単に答えを教えるのではなく、「どうしてこうなると思う？」と、まずは子供自身に理由を考えさせる間を作ってください。

◆出力ルール

1. 指定された学年への最適化
   ※未習得の漢字はひらがな、適切な言葉遣いにしてください。

2. 画像入力時は、含まれる内容を網羅的に拾い上げて解説に組み込んでください。

3. 興味のある分野を使った身近な例え話を交えてください。

4. 途中に必ずクイズを挟み、少し考える間を作ってから解説に進んでください。

5. 重要なキーワードは最初、途中、最後で繰り返し登場させてください。

The major benefits of this method

The beauty of this method is that it
"allows you to create materials tailored to your child while reducing the burden on parents."

It is especially useful in situations like the following:

• When parents are having trouble teaching

• When a child dislikes worksheets or cannot stay focused

• When the textbook is difficult and you want to explain it from a different angle

1. You can use analogies related to things the child likes

By drawing on the child's interests—such as using snacks or soccer for math, or dinosaurs for science—studying feels much more relatable and accessible.

2. The atmosphere softens with a "character teacher"

Set a knowledgeable owl or an energetic Shiba Inu as the teacher. By incorporating lines like "It's quiz time, woof!", it becomes easier for the child to accept the lesson naturally.

The greatest appeal of this method is that it allows you to change "Go study" into "Shall we take a look at this together?"

Things to keep in mind

Of course, I do not recommend leaving everything entirely up to AI.

When using this, please keep the following points in mind.

Especially when using it as learning material, it is safer for a parent to check it at the end to see:

"Is this explanation okay?"
"Is it saying anything incorrect?"
"Is it too difficult for the child?"

and confirm these points.

I think it is best to use AI not as a tutor itself, but as a
teaching material creation assistant to help with home learning.

Also,
please be careful about the copyright and personal information of the images you upload.

Summary

When we talk about home learning,
we tend to put too much effort into "making sure they do it properly."

But from a child's perspective,
"This is something that relates to me"
might be hard for them to feel.

That is why
even just changing the initial entry point a little
can change how easy it is to learn.

Having a favorite character explain it.
Using their favorite sport as an analogy.
Speaking in words appropriate for their grade level.
Having quizzes along the way so they have time to think for themselves.

Just by doing that, studying becomes a little more relatable.

By using Gemini Gems and NotebookLM,
you can create such materials quite easily.

Use Gems to create explanations tailored to the child.
Use NotebookLM to turn them into slides.
Include characters or their favorite subjects to make it a mini-lesson just for them.

Even just doing this can significantly change how it is perceived.

Instead of the parent doing everything, have the AI help with the preparation.
The parent checks it at the end, fixes what is necessary, and shapes it to fit the child.

If you use it with that kind of distance, I think the burden of home learning will become a little lighter.

Instead of saying "Go study,"
you can make it feel more like, "Shall we take a look at this with this teacher?"

I thought the beauty of this is that it makes creating such an entry point easy.
