Boards

Chalkboards

These are the most common instructional

media found in the classrooms

which commonly use a green board and a

chalk.

Whiteboard and Magnetic boards

also sometimes called as multipurpose boards are those with a glossy surface, commonly white in color, where non-permanent markings are made with the use of special felt pens. A whiteboard becomes a magnetic board when it is made with metal base and then used for posting with the aid of magnets.

Cloth Boards ( Felt, Flannel, and Carpet )This is a piece of plywood or heavy cardboard covered with either felt, flannel or carpet. The Fuzzy surface of a felt, , flannel or carpet allows visual materials with appropriate backing to adhere.

Hook& Loop Boards ( Velcro Boards) These boards are used in a similar fashion with cloth boards. Its edge over the cloth boards is that is has enough holding power to cause even heavy materials to stay on the board.

Bulletin Boards Are used to introduce or follow up lessons presented. These boards are usually designed as an instructional device that can carry a message without the presence of a teacher.

Pegboards Pegboards are made tempered masonite with 1/8-inch holes drilled 1 inch apart. These boards are used in displaying three-dimensional objects or heavy materials with the use of hooks inserted into the board.

Graphic Materials

This employs the use of lines, either simple or crude. They may not be the real thing but they may represent persons, places, things, and concepts.

Drawings and Sketches

CartoonsAre use as

Bar GraphsAre the simplest and easiest to read. The data are presented in horizontal or vertical bars. While the widths of the bars are the same, its length represents the amount or percentage data.

Pie Graph or Circle graphThe sections of these kinds of

graphs represent the parts of a whole. These graphs always present whole

amounts and its parts are calculated

in percentage or fractional parts

Area or Solid graphsThey are used to compare several

related totals thru the use of geometric shapes.

Pictographs

These graphs utilize related pictures or drawings to show numerical data. It is an adaptation of the bar graph.

Diagrams

Cluster or Cloud Diagram This is used in a nonlinear activity

wherein ideas, images, and feelings are generated around a stimulus word.

Chain of Events

This diagram illustrates the stages of an event, the

actions of a character more the steps in a

procedure.

Fishbone MappingA fishbone map is used to show casual interaction of a complex event ( like nuclear explosion) or a complex phenomenon (like learning disabilities)
