Teachers don't necessarily need another giant platform.

Sometimes the most useful digital tool is a small website that solves **one annoying problem really well**.

Need a quick classroom timer?

Want students to manipulate fractions visually?

Need to clean up an image before putting it into a worksheet?

Want a collaborative diagram without creating accounts for everyone?

There are tools for all of these things.

Here are seven worth keeping somewhere in your bookmarks.

## 1\. Mathigon Polypad

**For exploring mathematics visually**

[Open Mathigon Polypad](https://mathigon.org/polypad?ref=digitalteachernotes.com)

Polypad is essentially a digital playground for mathematics.

Instead of simply looking at diagrams, students can manipulate objects directly on an interactive canvas.

There are fraction bars, number tiles, polygons, tangrams, probability tools, graphs, geometric solids and many other virtual manipulatives.

That opens up activities such as:

**Can you show 3/4 in three different ways?**

**What happens to the area when you change this shape?**

**Can you build a pattern and explain the rule?**

Mathigon says Polypad contains more than 50 different virtual manipulatives, and its teacher resources are free.

It's particularly useful when you want students to **play with a mathematical idea before formalizing it**.

**Worth bookmarking for:** mathematics exploration, demonstrations and visual problem solving.

## 2\. Photopea

**For editing almost any image in your browser**

![](https://storage.ghost.io/c/63/80/6380299b-989e-4213-96e2-1c30c5338782/content/images/2026/09/Photopea.jpg)

[Open Photopea](https://www.photopea.com/?ref=digitalteachernotes.com)

Sooner or later, every teacher seems to encounter an image that needs fixing.

Maybe it needs cropping.

Maybe you need to remove a background.

Maybe a worksheet contains an image that's the wrong size.

Maybe somebody sends you a PSD file and you have absolutely no desire to install Photoshop.

Photopea is a surprisingly powerful image editor that runs directly in a web browser.

It supports layers, masks, text, filters, PSD files and many other advanced features, but you don't need to understand any of those things to use it for simple jobs.

One particularly useful detail is that Photopea says files are processed **locally on your device** rather than uploaded to its servers.

That doesn't remove the need to think carefully about student data, but it's a useful distinction from many online file-processing tools.

**Worth bookmarking for:** cropping, resizing, removing backgrounds and quickly fixing classroom graphics.

## 3\. Wheel of Names

**For choosing almost anything randomly**

![](https://storage.ghost.io/c/63/80/6380299b-989e-4213-96e2-1c30c5338782/content/images/2026/09/Wheel.jpg)

[Open Wheel of Names](https://wheelofnames.com/?ref=digitalteachernotes.com)

This is exactly what it sounds like.

Paste in a list.

Spin the wheel.

Get a random selection.

That's it.

You can use it for choosing a student to answer, assigning groups, selecting discussion questions, deciding which activity comes next or adding some randomness to revision.

And it doesn't have to contain names.

Put vocabulary on the wheel.

Put historical events on it.

Put writing prompts on it.

Put mathematical problems on it.

Spin.

Then ask the class what to do with whatever appears.

Could you accomplish the same thing by drawing something from a hat?

Of course.

Is the giant spinning wheel somehow more exciting?

Also yes.

**Worth bookmarking for:** random selection, discussion prompts and quick classroom games.

## 4\. Excalidraw

**For diagrams that don't look like corporate flowcharts**

![](https://storage.ghost.io/c/63/80/6380299b-989e-4213-96e2-1c30c5338782/content/images/2026/09/Excalidraw.jpg)

[Open Excalidraw](https://excalidraw.com/?ref=digitalteachernotes.com)

Excalidraw is a digital whiteboard with a deliberately hand-drawn visual style.

You can add boxes, arrows, drawings, text, images and connections, then collaborate with other people on the same canvas.

It's wonderfully quick.

You don't have to spend ten minutes aligning everything perfectly before you can explain an idea.

That makes it useful for:

- concept maps
- processes
- timelines
- brainstorming
- explaining relationships
- planning projects
- working through problems visually

The rough appearance is actually part of the appeal.

Sometimes a diagram that looks unfinished invites students to **change it, question it and add to it**.

**Worth bookmarking for:** visual explanations, brainstorming and collaborative thinking.

## 5\. Classroomscreen

**For turning the classroom display into something useful**

![](https://storage.ghost.io/c/63/80/6380299b-989e-4213-96e2-1c30c5338782/content/images/2026/09/Classroomscreen.jpg)

[Open Classroomscreen](https://classroomscreen.com/?ref=digitalteachernotes.com)

A projector or interactive display often spends half the lesson showing a desktop or a presentation slide.

Classroomscreen turns it into a simple classroom dashboard instead.

You can display instructions alongside useful widgets such as a timer, clock, work symbols and other classroom tools.

It's particularly handy during independent or group work.

Instead of repeatedly answering:

**How much time do we have?**

**What are we doing?**

**What happens when we're finished?**

the information can stay visible at the front of the room.

The basic version can be used for free, while some additional functionality requires a paid plan.

**Worth bookmarking for:** classroom routines, timed activities and keeping instructions visible.

## 6\. Vocaroo

**For recording audio without turning it into a project**

![](https://storage.ghost.io/c/63/80/6380299b-989e-4213-96e2-1c30c5338782/content/images/2026/09/Vocaroo.jpg)

[Open Vocaroo](https://vocaroo.com/?ref=digitalteachernotes.com)

Sometimes you just need to record your voice.

Not create a podcast.

Not configure a recording studio.

Not sign an entire class up for a new platform.

Just record something.

Vocaroo has been around for years because it makes that remarkably easy.

Open the site, press record, speak, stop, and share the resulting recording.

For teachers, that can be useful for:

- pronunciation examples
- verbal instructions
- language practice
- short explanations
- listening activities
- spoken feedback

Students can also use it when the learning task is better demonstrated through speaking than typing.

As with any external service, avoid recording sensitive personal information and check your institution's rules before using it with students.

**Worth bookmarking for:** quick voice recordings and language activities.

## 7\. Remove.bg

**For the five-minute design job that should take five seconds**

![](https://storage.ghost.io/c/63/80/6380299b-989e-4213-96e2-1c30c5338782/content/images/2026/09/Remove.bg.jpg)

[Open remove.bg](https://www.remove.bg/?ref=digitalteachernotes.com)

You have a photo.

You want the person or object.

You don't want the background.

That's the entire problem.

Remove.bg automatically removes image backgrounds.

There are plenty of larger design applications that can do the same thing, including Photopea from earlier in this list.

But sometimes a dedicated tool is better because there's almost nothing to learn.

Upload.

Remove.

Continue with your work.

The free version has limitations, particularly around output resolution, so this isn't a replacement for a full image editor.

But for quick classroom graphics, slides and simple visual materials, it can be extremely convenient.

**Worth bookmarking for:** quick background removal when high-resolution output isn't essential.

## The best tools aren't always the biggest ones

There's a tendency in EdTech to evaluate products by how much they can do.

AI.

Analytics.

Assignments.

Collaboration.

Content creation.

Dashboards.

Sometimes that's exactly what you need.

But there's another category of technology that's easy to underestimate:

**the tiny tool that solves today's problem in 30 seconds.**

You don't need to build a workflow around it.

You don't need to transform your teaching.

You don't need to attend a webinar.

You just open it, do the thing and continue with your day.

Those tools deserve bookmarks too.
