Project goals:
1. Science students will find out the type of chemical (paints) used in the writing
2. Graphic students will look out for the type of lettering used 
3. Mathematics students will look at the positions and angles of the posts
4. English students will look at the grammar and the language used.

Subject:  Mathematics -      &nbbsp;    Grade Level 17 - 18 years.

Project goals/aims: 
By the end of the lesson, students should be able to: 
1. Relate the size of the sign post to how easy it can or it cannot break;
2. Determine the appropriate angle(s) at which a sign post should be placed to serve its rightful purpose;
3. Determine the right height for specific sizes of sign post to prevent its breakages;
4. Tell the geometric shape that will look attractive.

Lesson Content Objectives:
I. Measure the sizes of the sign posts on their rounds,
II. Find out the appropriate angles at which a sign posts has to be placed in order to make pedestrians and those on board a vehicle can easily read from the sign post,
III. Find out how high a sign post should be in relation to its size and thickness,
IV. Prescribe the shape that will look more attractive to readers when used in making a sign post.

Performance Objectives:
1. Students should try and relate the height of signposts to how firm they are, as well as how               deep a whole should be dug to ensure the firmness of the signposts.
2. Relate the position of signposts to the direction from which readers would come from.
3. Find out if the height, size, thickness and angle at which a signpost has been positioned can withstand the test of time. Thus, in the event of rain, wind, accidents, etc.
4. Students will use MS Excel and MS Power point to analyze and process their data.
5. Students research from the Internet on sign posts

Technology Objectives: 
 Use  MS Excel in analyses and search engines such as google, yahoo, etc. to find out more on signposts.

Instructional Activity (teacher component)
I discussed thoroughly with the students what the questionaire entails.

Mathematics (Questionnaire)
Students are to estimate the following about the sign post they come across,
1. size of sign post
less than 2m     3m - 4m     5m or more
2. height  of sign post
less than 5m      5m - 7m     8m or more
3. direction of sign post
North             South  East  West               others 
4. Shape of sign post
         Square      rectangular             circle               others
5. comment
too long    too small   regular  irregular  too big
6. nature of direction
misleading    yes  no  easily noticed    yes  no  easy  to read    yes  no
7. number of broken sign post
less than 10  15 - 20     25 or more
8. comment
wind human    car accident       others
 

Data collected
The students were put inot groups of ten in the computer lab.  They were made to discuss their findings and using excel find the percentages of the data collected.
1. size of sign post
less than 2m  20%
3m - 4m     60%
5m or more  20%
2. height  of sign post
less than 5m  20%
5m - 7m     55%
8m or more  15%
3. direction of sign post
North               4  students
South   15%
East   20%
West                 50%
others    15%
4. Shape of sign post
          Square                20% 
rectangular          50%
       circle               20%
    others   0%
5. comment
too long    16%
  too small    16%
  regular               57%
irregular   10%
too big   1%
6.   nature of direction
misleading 
yes     30%
no    70%
7.  easily noticed 
yes     25%
no    75%
8.  easy  to read 
yes     30%
no   70%

9.  number of broken sign post
less than 10  70%
  15 - 20     20%
  25 or more  10%
10. comment
wind    20%
human                 40%
car  accident       15%
others    15%

Conclusion :- 
Based on their findings, the students made the following suggestions in a form of a conclusion;
Signposts are not just to be erected without taking a lot of things into consideration. 
If you want your signpost to stay long, then you need to take the size of the signpost, the direction of wind in the area, the height of the signpost and the shape of the signpost among other things into consideration.
