Lesson 18 – Fraction – Word problem

We started today’s lesson with solving a word problem given by one of our classmate.

Hassam has ½ litre of orange juice. He needs 5/7 litre of orange juice. I have to change the denominator to be a common denominator and that is 14. So it is 10/14 – 7/14

___________1/2__________________ ===He needs this much=

5/7-1/2

10/14 – 7/14 answers 3/14

Today, I learned two new words again that are application level task and assessment task.
Bloom’s Taxonomy. For Primary 5 this problem sum is of a comprehension level

Bloom’s Taxonomy:

1. Knowledge level

2. Comprehension level

3. Application level

.Lesson 20

George pick theory says that the area of a figure is related to the dots. Pick theorem says that the area of the figure is by counting the dots inside and add to the perimeter.

Some more new words learned today and that is reflect, rotate, translate, sheer and pull, this are some of the words we can use when we want to change the position of the shape. These are the 5 transformation for changing shape.

Number of dots
4 dots at the side and 1 dot in the centre = 2 squares

4+0 = 1 square

4+2 = 3 squares
Look at the picture below.
