Introduction to Mathematics as a School Subject

Before we venture into Past Mathematics Exam Questions for JSS1 First term, here’s a brief introduction to the subject:

Mathematics is one of the most important subjects taught in school. It deals with numbers, shapes, measurements, and logical thinking. Mathematics helps us to solve problems in our daily lives — from counting money and measuring objects to telling time and calculating distances.

It is often called the language of science because it is used in almost every field of study, including engineering, medicine, business, and technology. Learning Mathematics trains the mind to think clearly, reason logically, and make accurate decisions.

In school, Mathematics is divided into different branches such as Arithmetic, Algebra, Geometry, Statistics, and Mensuration. Each branch helps students develop problem-solving skills and prepares them for higher studies and real-life challenges.

Answers to Mathematics Exam Questions for JSS1 First Term

Answers to Section A (Objective Test)

The following table gives the correct answers to the objective section of Mathematics exam questions for JSS1 First term. If you are using a mobile device, hold the table and scroll to the right or left for a complete view.

So here you have the answers to the objective section of Mathematics Exam Questions for JSS1 First term. Use the comments section to let me know if you have any questions you would want me to clarify or discuss further.

Answers to Section B (Theory)

1.
(a) The first ten multiples of 4 are: 4, 8, 12, 16, 20, 24, 28, 32, 36, and 40.
(b) The factors of 24 are 1, 2, 3, 4, 6, 8, 12, and 24.
The factors of 36 are 1, 2, 3, 4, 6, 9, 12, 18, and 36.
The common factors are 1, 2, 3, 4, 6, and 12.
Therefore, the H.C.F of 24 and 36 is 12.

2.
(a) To arrange ¾, ⅖, ⅝, and ⅗ in ascending order, convert them to decimals:
¾ = 0.75, ⅖ = 0.4, ⅝ = 0.625, ⅗ = 0.6.
So, the ascending order is: ⅖, ⅗, ⅝, ¾.
(b) Simplify ⅔ + ⅙ − ½:
The LCM of 3, 6, and 2 is 6.
= (4/6) + (1/6) − (3/6) = (4 + 1 − 3)/6 = 2/6 = ⅓.

3.
(a) Perimeter of a rectangle = 2(L + B) = 2(12 + 8) = 2 × 20 = 40 cm.
Area = L × B = 12 × 8 = 96 cm².
(b) Draw a rectangle with a length of 12 cm and breadth of 8 cm using a ruler.

4.
(a) Convert 2.75 to a fraction:
2.75 = 2¾ = (11/4).
(b) Evaluate 0.35 × 0.2 = 0.07.

5.
(a) Perimeter of a triangle = sum of its sides = 5 + 7 + 9 = 21 cm.
(b) Since all the sides are different, it is a scalene triangle.

6.
(a) A man earns ₦25,000 per month. In one year (12 months):
₦25,000 × 12 = ₦300,000.
(b) ₦25,000 as a fraction of ₦100,000 = 25,000 / 100,000 = ¼.

7.
(a) Mean = (6 + 9 + 12 + 15 + 18) ÷ 5 = 60 ÷ 5 = 12.
(b) To draw a bar chart, label the x-axis with numbers 2, 4, 6, 8, 10 and the y-axis with their frequencies. Draw bars of equal width and appropriate height for each value.

How to Pass Mathematics Exam Questions for JSS1 First Term

Passing your Mathematics exam questions for JSS1 First term requires a combination of preparation, understanding, and strategy. Here are actionable tips to help you excel:

1. Make a study plan

• List the topics for the term (numbers, fractions, HCF/LCM, decimals, area, etc.).
• Spend more time on weak topics. Spend less on topics you know well.
• Study in short sessions (30–45 minutes). Rest between sessions.

2. Learn the basics well

• Master place value, basic operations and fractions first.
• Know times tables up to 12 × 12 by heart.
• Practice converting fractions, decimals and percentages often.

3. Practice with purpose

• Do past questions and school tests. They show exam style.
• Time yourself for practice papers. Build speed and accuracy.
• Work on one skill at a time (e.g., add fractions for 15 minutes).

4. Use simple methods and show working

• Write clear steps. Examiners like neat working.
• Use column methods for addition, subtraction, multiplication and division.
• For word problems, read twice and underline key numbers.

5. Exam-day rules

• Arrive early and bring necessary tools (pens, pencil, ruler, eraser).
• Read all instructions carefully. Check number of questions to answer.
• Do easy questions first. Mark hard ones and return to them later.
• Show clear working even for multiple-choice questions.

6. Time management in the paper

• Divide time: spend little time on each objective question.
• Leave 20–25 minutes at the end for revision and tricky questions.
• If stuck, move on. A fresh look later often helps.

7. Common mistakes to avoid

• Rushing and making careless calculation errors.
• Forgetting units (cm, m, ₦) in answers.
• Using wrong order of operations. Remember brackets first.
• Not simplifying fractions or giving answers in required form.

8. Build confidence

• Practice a little each day. Small wins add up.
• Teach someone what you learned. Teaching helps memory.
• Rest well the night before the exam. A fresh mind works better.
