Pattern Blocks is an online mathematical manipulative that helps students develop spatial reasoning. As students become more familiar with composition and decomposition of shapes, they start to recognize "patterns," which is one of the most important standards of mathematical practice.

Pattern Blocks is a versatile manipulative that can be easily accessed by students of any age for remediation or enrichment.

Modeled off of the original pattern blocks developed in the 1960s, our virtual pattern blocks include a yellow hexagon, red trapezoid, orange square, blue rhombus, beige narrow rhombus, and green equilateral triangle, offering a helpful complement to the concrete manipulatives found in classrooms. Designed using physics, these online pattern blocks can be rotated, moved around, and bumped into each other giving the feeling of real blocks. However, this virtual manipulative offers the added advantages of requiring no clean up and they're free! Also check out our Tangram activity for another way to explore shapes and spatial rotation. Visit classplayground.com for pattern block printables. We have also collected the pattern block printables into a book, available from Amazon.

This is a transparent online protractor, you can easily measure the angle of any object around you, and it helps you measure angles in a picture, taking a picture and uploading it, then dragging the midpoint of the protractor to the vertex of the angle, our virtual protractor is very accurate, it can zoom in, zoom out, rotate and move position.

How to use this online protractor ?

You can measure the angle of any actual object directly on your screen

If you want to move the protractor, drag the midpoint of it.

If you want the protractor size to be smaller or larger, you can change the protractor radius

You can rotate the protractor just like the traditional protactor

Click the edge outside of the protractor will add a pushpin on it

Placing two pushpins will show the degrees of that angle

Double click on the pushpin will remove it, drag it to move its position

These actions can also be done in the buttons inside the control panel

Choose a picture as the background, the background can be zoomed in and out, and our protractor can measure directly on the picture

You can drag and drop a picture into the background.

Press Ctrl+V can paste the image to the background.

You can download your design and share it with others, this is free

The browser on the mobile phone does not support drag and drop operation, just use the buttons

If you want a bigger workspace, try the full screen mode(F11)

The story of our protractor

Every time I want to measure the angle, I always can't find the protractor. After I tried other peoples's virtual protractors on the Internet, I didn't feel very satified, so I decided to created a more practical online protractor by myself. This idea was in my mind, I thought about it for a whole year, and then I took some time to make it when I was free.

Such a convenient and useful thing, I must share it with you all, so we're all lucky today, here is a handy and useful online protractor. Now, we can measure the angle of anything around us anytime, anywhere using our laptop, computer, tablet or smartphone.

If you want to measure something that is small, just place it on the screen and measure it directly; If you want to measure something bigger, you can take a picture and upload it, then move the center point of the protractor to measure its angle.

Use camera or image to measure angle

You can take picture of any object that you would like to measure, for example, a car, road, house, stairs or a mountain, the protractor is transparent, after you uploaded the image, it will be display in the background. then, you can drog the protractor or add pushpins to figure out the degrees of angles, upload file only accept image file in formats of jpg, gif, png, svg, webp.

In the control panel, if the background color is close to the protractor, and it's not easy to distinguish, you can change a protractor color to see it clearly. Also you can move it, shrink or enlarge the size of protractor, according to your needs.

Angles and Degrees

Angles are measured in degrees, the symbol for degrees is a little circle °

The full circle is 360° (360 degrees)

A half circle or a straight angle is 180°(180 degrees)

A quarter circle or a right angle is 90°(90 degrees)

How to measure an angle with a protractor

Place the midpoint of the protractor on the vertex of the angle.

Line up one side of the angle with the zero line of the protractor (where you see the number 0).

Read the degrees where the other side crosses the number scale.

Take care to read from the right set of numbers.
A protractor has two sets of numbers: one set goes from 0 to 180, the other set from 180 to 0.
Which one you read depends on how you place the protractor:
place it so that one side of the angle lines up with one of the zeros, and read that set of numbers.

What do you think of this protractor ?

Thanks for your comments, I've read these.
Rotate the protractor -- I've added it.
Larger work space -- I've enlarged it
Paste the image to the background(Ctrl+V) -- I've added it.
Thank you all for your support and sharing, enjoy to use it, it's free.
