1. Topic-
Calculating Angles
 
2. Content-
Teaching a student with a Statement of SEN how to work out the value in degrees of angles around a point. Student has dyscalculia, ADHD and dyspraxia and is a kinesthetic/visual learner.
 
3. Goals: Aims/Outcomes-
1. To understand that angles around a point add up to 360°.
2. To understand that the total of known angles around a point taken away from 360° will give the unknown angle/s.
 
4. Objectives-
1. Explain how to work out angles around a point.
2. Complete 20 questions on finding the unknown angles around a point.
 
5. Materials and Aids-
Dry erase board, board marker, grid paper, pencil with hand grip, triangular hand hugger pen, mathematics workbook, ruler, strips of paper held together with brass fasteners so that the strips of paper can be moved about to create angles, oversized protractor.
 
6. Procedures/Methods-

A. Introduction-

1. Inform student that the lesson will be on calculating the angles around a point.
2. Remind student that the previous lesson was on calculating the angles on a straight line. Draw a straight line on the dry erase board.
3. Ask student what the angles on a straight line add up to (180°). Draw a circle through the middle of the line. Explain that adding the other side of the line (180° + 180°) equals 360°.
 

B. Development-

1. Place 4 strips of paper fastened together by one pin at the end of each strip on the table. Explain that this represents the angles around a point. Using an oversized protractor, measure the angles and confirm that they add up to 360°.
2. Use a board marker to draw 3 different angle values in between the strips of paper, leaving one angle blank (the unknown angle).
3. Ask how to calculate the unknown angle. (Answer: add up known angles and take these away from 360°).
 

C. Practice-

1. Give student an example question to complete.
2. Remind them of the steps needed to complete the task by pointing to the instructions in the math book.
3. Provide encouragement at each step and praise when it has been completed.
 

D. Independent Practice-

1. Complete 10 questions with one unknown angle to work out and 3 known angles.
2. Complete 10 questions with two unknown angles and 2 known angles.
 

E. Accommodations (Differentiated Instruction)-

1. Over-learning: repetition of the steps involved in the calculation.
2. Use of physical objects and diagrams to reinforce mathematical concepts.
3. Regular verbal reminders to stay on task and encouragement and praise to motivate student.
4. Triangular hand hugger pen and pencil with grip to enable student to write with greater legibility and draw diagrams correctly.
 

F. Checking for understanding-

1. Ask student the steps involved in working out the answer during the demonstration and the practice question.
2. Mark work with ticks for questions answered correctly and ask student to retry any questions that are incorrect.
3. Give verbal feedback on the student's achievements and write a constructive comment on their work.
 

G. Closure-

1. Ask student what the angles around a point add up to and how to work out an unknown angle.
2. Praise efforts made and announce any achievement points to be awarded.
 
7. Evaluation-
1. Student displayed very good understanding of the concept of angles around a point adding up to 360° and how to calculate any unknown angles.
2. Student completed all questions correctly and stayed on task throughout the lesson.
3. Student given achievement point.
 
8. Teacher Reflection-
Accommodations during the lesson were very successful in teaching the student the concept and helping the student to remember it.

The student often finds math difficult and finds it a challenge to recall steps involved in a calculation but was able to complete the task due to over-learning and the use of concrete materials and diagrams.

The student also responded well to praise and motivation as sometimes the student becomes distracted or loses focus.

The student's work was neat and legible and this was helped by using the ruler, triangular hand hugger pen and pencil with grip on it.
