3. What is a CHALKBOARD?
- A smooth, dark surface that is used for writing on
with chalk in a classroom which is usually used by
students and teachers.
- Often called as BLACKBOARD.

4. A good chalkboard should be within reach of the learners. The
height of the board from the floor should be at most….
28 inches for Grades 1-2
32 inches for Grades 3-4 and
36 inches for Grades 5-6

6. ADVANTAGES
1. Chalkboards are readily available.
2. Chalkboards are inexpensive and easy to install.
3. Chalkboards can accommodate so much writing space
and are easy to clean.
4. Chalkboards are convenient to use both for formally
prepared lessons or spontaneous lessons.
5. The attention of the class can easily be held and
focused.

7. LIMITATIONS
1. Lessons or writings on the board can only be limited
for a day’s use, hence, temporary and cannot be saved.
2. Chalkboards are always dusty.
3. Writing makes one turn his back to the audience.
Writing may not always be seen by everyone in the
classroom.
4. The teacher’s handwriting and spelling deficiency can
cause disruption of the lesson.

8. UTILIZATION GUIDELINES
1. Protect the writing surface with proper cleaning and
use appropriate writing materials.
2. Avoid filling the board with so much writing that
students get confused.
3. For materials which will require time in writing, they
could be written in advance.
4. Write legibly and neatly. Keep your words large
enough. Write from left to right.

9. Why are some blackboards “green”?
The meaning of the blackboard can be defined with stress
given to the words of the compound noun.
• The room has a blackboard. (The stress is on the word board. It
means a board that is painted black.)
• The room has a blackboard. (The stress is on the word black. It
means any writing slate.)
