Grade 2 Mathematics Whole Numbers – Fractions Circular Cutouts In Quaters Notes
Mathematics — Whole Numbers
Subtopic: Fractions — Circular Cutouts in Quarters
Age: 7 (Kenya). Simple idea: a circle can be cut into 4 equal parts. Each part is called a quarter (English) or robo (Kiswahili).
4/4 = 1 whole
All quarters are together
3/4 (one quarter cut out)
3 of the 4 quarters are present
1/4 = a quarter (robo)
One out of four equal parts
2/4 = 1/2
Two quarters make half a circle
Simple Points to Remember
- A quarter = 1 of 4 equal parts. Write it as 1/4.
- Two quarters (2/4) is the same as one half (1/2).
- Four quarters (4/4) = 1 whole circle.
- Cutouts show missing parts. If one quarter is cut out, three quarters remain (3/4).
Activity (use paper circles)
Give each pupil a paper circle. Ask them to:
- Fold the circle into 4 equal parts (make 2 folds).
- Colour 1 quarter and write 1/4.
- Cut out 1 quarter. How many quarters remain? (Answer: 3/4)
- Put 4 quarter pieces together to make one whole circle.
Questions — Try These
1. If you shade 1 quarter of a circle, what fraction is shaded?
Answer: 1/4
2. If two quarters are shaded, what is the fraction and its name?
Answer: 2/4 which is 1/2 (one half)
3. If one quarter is cut out from a circle, what remains?
Answer: 3/4 (three quarters remain)
4. How many quarters make 2 whole circles?
Answer: 8 quarters (because 4 + 4 = 8)
Teacher tip: Use real round objects (plates, lids) or cut-out paper circles. Let learners fold, colour and join pieces — learning is easier when hands do the work.
