Welcome to the virtual online graph paper. Here you can easily draw lines, text, and print your graph paper. To draw lines just click anywhere in the grid below and drag while holding the mouse button. To write text instead just click anywhere and start typing. To see it in action: How to use virtual graph paper video. Virtual Online Graph Paper. This virtual graph paper lets you draw lines and write text on it right from your computer. If you make a mistake you can easily undo it. It will remember what you draw unless you erase it so you don't have to worry about losing it. And to top it off it's printable.

This activity allows manipulation and investigation of various types of angles. The online protractor tool can be used to practice measuring angles. It can be used at a variety of different grade levels. At its most basic for teaching about types of angles, acute, obtuse or reflex. For more advanced use to create angle problems in which the missing letter angle values have to be found. You can click and drag the handles to change the angles and the values will updated.

The controls

  • The mode control is used to it selects the type of angle problem.
  • Next to this is number of lines. But please note this control is disabled for both 'one' and 'intersect' modes.
  • the random button sets each angle to a random value
  • the equals button make all the angles equal.
  • the Protractor button when clicked will show or hide a protractor
  • Paper can select spots, squares or none for the background.
  • Use the angles display to choose whether to show or hide angles

In all the modes individual angles can be shown or hidden for example click the angle (a). Notice when the value is hidden the angle value next to the angle arc is replaced by the corresponding letter.

The handles at the end of each line can be clicked and dragged to change the angle.

Mode 'one' Identifying angle types.

The initial mode is unique in that there is only one angle. This mode is great for identifying various types of angles. Click the angle type ctrl to either show or hide the type. So now you can change the angle by dragging a handle or clicking dice for a random value. The angle types definitions are listed in the glossary below.

Complementary Angles mode

In this mode a complementary angle is shown, complementary angles add up to 90° Initially the 90° is split by just one line but this can be changed by selecting a different number of lines. A standard school problem is to have one missing angle that needs to be calculated. You can produce infinite such problems by selecting calculate from angles display, now press dice for a new problem.

Supplementary Angles mode

Supplementary angles are angles that add up to 180°. This mode behaves exactly the same as the previous.


Angles at a point mode

The angles at a point add up to 360°. In this mode press = button to make all the angles equal. This can be good way to start a problem followed by small adjustments to the lines by dragging.

Angles at intersecting lines mode

The final mode deals with angles produced by an intersection of two lines. If you have selected calculate you will notice that only one angle is given and all the other 3 can be worked out using the vertically opposite rule, or spotting the supplementary angles.

Virtual manipulatives are visual objects on the computer screen that the student can manipulate through mouse clicks, or through drag-and-drop movements, which moves or modifies that visual object in some way.
The learning process comes from the student observing the behavior of the object and then understanding how and why it changes the way it does after being manipulated. This 'understanding' makes up the learning process through virtual manipulatives.

Main Page of Glencoe Manipulatives

When you first access the Glencoe virtual manipulatives tool, it looks a lot like a paint or drawing application. At the bottom you'll find multiple tools you can use to draw such as the pen tool or the text tool. There's also a color palette, which you'd expect in a paint program.
However, the first sign of something different is the fact that this toolbar also includes a ruler, a stopwatch, a protractor and a timer. In the left menu bar, you'll find options to select a grade, background graphics, or a choice of manipulatives.

Choosing a Grade

Once you choose the grade level, the other two menu items adjust accordingly to only include the choices that are age appropriate. The Backgrounds menu item includes Game Boards, Story Boards and Workmats. Each of these three backgrounds represents an environment within which the student can manipulate objects and learn.

Choosing a Background

The variety of choices in each of these options is impressive. Once you start using this tool, it's difficult to believe that it's absolutely free. Game board backgrounds include choices like Finding Shapes, Leap Frog or Surf's Up. Story Boards include things like Baseball Diamond, Box Ten-Frame or Chalkboard.
Workmats are simply layouts that teach different lessons, including Black Calendar, Part-Part-Whole and Horizontal Split. Many of these titles have little meaning until you open it up and start 'manipulating.' The purpose of each choice quickly becomes apparent.

Boat for Bears

Each manipulative starts off with a screen that requires the student to grab objects and drag them onto the work 'mat.' The goal is to learn and understand what makes each object behave a certain way. The procedure is about as simple as it can get, click on, move and otherwise try to manipulate the objects and learn from how it changes.

Boat for Bears in Use

First, dragging each of the objects onto the mat doesn't seem to do much at all. Even dragging each bear on top of the other does nothing. However, once you drag the boat onto the mat and start clicking on it, it quickly becomes apparent that this particular manipulative requires the Kindergarten student to correctly place each bear over a seat.

Boats for Bears Sitting

When they do, the bear then sits on the seat and faces the front of the boat. While this may seem like a simple concept, it's important to understand that virtual manipulatives are tied closely to the developmental stages of the chosen age group, and for a Kindergarten student this is an appropriate lesson with colors, images and an method to organize and order the bears on the boat.

Base Ten Blocks

As you choose higher grade levels, the objects and behaviors become a bit more complex. For example the Base Ten blocks teach the student about Base Ten values. How does this work when the screen simply starts with a cube filled with smaller cubes? Well, all you have to do to find out is click on the box at the lower corner of the cube.

Manipulating Base Ten

As you can see, this splits the cube into 10 smaller pieces, also made up of smaller cubes. Click again on one of these sections, and it breaks up into 10 smaller pieces. Click each of these objects and it also gets broken into 10 more pieces, until you are down to the smallest possible unit.

Breaking Down Base Ten Blocks

You can even place units back together, move them around the screen, break apart some units and leave others intact. The goal of such an activity online is to recognize through interacting with the object that it splits into the base ten of the original number of elements.

Bucket Balance

There are all sorts of interactive objects that you can alter, rotate, resize or otherwise modify in order to cause some sort of reaction to the behavior or appearance of the object. For example, in 'Bucket Balance,' the student places weights of various size into the buckets on each side of a scale, which rises or falls accordingly.
While using imagery or interactive animation as part of any learning process is a fairly new concept in education, more teachers and educators are realizing that the approach has many benefits, particularly for disabled or developmentally challenged children. Virtual manipulatives can serve as a powerful tool in any teacher's educational toolbox.
