C. Motivation
*(Hanapin mo ang kasama ko)
*Finding the pair of object in order to form a similar fraction and after that adding all the newly found objects by using their corresponding fraction as written on the object. B. 1. Presentation

Amy and Iris were invited in a party. Amy eats 2/4 of the whole cake, and Iris eats twice as much Amy has eaten. How many parts of the cake they have eaten in all? Amy- 
2/4
Iris- 
4/4
Now, we will use shaded and not shaded blocks to represent the parts of the cake that they have eaten in all. So, out of six parts of the cake, Amy has eaten two parts of it, while Iris has eaten four parts of it. Thus, the shaded blocks represent the total parts of the cake they have eaten in all. Therefore; 2/4+4/4= 6/4 or 1 and 2/4

6/4- total parts of the cake did Amy and Iris have eaten in all. 2. How many parts of the cake did Amy and Iris eat in all?
