There are mixed numbers which are 3 2 and 7 5.
Motivation
Ask the following questions:
1. How often do you have visitors during weekends?
2. What do you do if you have visitors?
3. How can you entertain the visitors?
Explain to the pupils that Filipinos, when having visitors, shows the value of being

What did your mother bake? And for whom?
My mother baked buko pies for my visitors.
Have you seen a buko pie? What does it look like? Can you draw it for the whole
class?
Yes. A buko pie is in a circular shape.
8 8 7
8 8 8
The figure shows two complete buko pies and one buko pie with seven remaining
7
slices. It shows 2 and 7/8 buko pies or 2 8 buko pies.

Solution 2: By division
23
= 23 ÷ 8 = 2 𝑟𝑒𝑚𝑎𝑖𝑛𝑑𝑒𝑟 7
8
23 7
Express the remainder as a fraction. So, 8 = 2 8
For Solution 1:
Devising a Plan:
Our plan was to use a drawing or regions to show the buko pies my mother baked,
23
and counting the number of whole buko pies and slices from the 8 buko pies that
were left.
Looking Back:
From our solution, we saw that the problem can be solved using simple division.
For Solution 2:
Devising a Plan:
Our plan is to use simple division since we will determine how many whole buko pies
23
and slices are in 8
Looking Back:
We can visualize the problem using a diagram with shaded regions for the slices of
the buko pies.

Parts of the Lesson Description of Activities
After presenting the outputs, ask the following questions:
1. What two concepts in fractions did we involve in our activity?
The activity involved improper fraction and mixed numbers.
23
3. What process happened from the fraction 8 in the problem? How?
The activity we did changed the improper fraction to a mixed number in two
ways – using regions and using division.
Explain the process to the pupils or let a pupil explain the process. The numerator
will be divided by the denominator. Reiterate that if there is a remainder, it will be
expressed as a fraction.
Elaborate What if you ate three slices before serving the buko pies to your visitors? How many
whole buko pies and slices will be served to your visitors?
21
There will be 8 buko pies left. So, using division, it will be
21
= 21 ÷ 8 = 2 𝑟𝑒𝑚𝑎𝑖𝑛𝑑𝑒𝑟 5
8
5
This can be written as 2 8 buko pies.
