Students are able to compare and arrange fractions and mixed numbers from different situations; write the ratio to show the comparison of 2 amounts which are cardinal numbers from given messages or situations; find the ratio which can be matched to the given ratio; find the greatest common factor and the least common multiple of not more than 3 cardinal numbers; show method of finding answers to problems by using the greatest common factor and the least common multiple; find the answer for mix addition, subtraction, multiplication and division of fractions and mixed numbers; show method of finding answers to 2-3 step problems of fractions and mixed numbers; find the quotient of the decimal which the divisor and the quotient are the decimals not more than 3 places; show the method of finding the answer to 3 steps addition, subtraction, multiplication, and division decimal problems; show the method of thinking and finding the answer to problems involving patterns; show the method of finding the answers to the problems involving the volume of 3-D geometric shapes which are composed of cuboids; show the method of finding the answer to the problems involving the perimeter and the area of polygon; show the method of finding the answers to the problems involving the perimeter and the area of a circle; classify a triangle by considering from its properties; construct a triangle when giving the length of each side and the size of the angle; tell the characteristic of 3-D geometric shapes; identify the 3-D geometric shapes which are from the unfolded shapes and identify the unfolded shapes of 3-D geometric shapes; use the information from a pie chart to find the answer for the problems.

These can be done through the determined situations for the students to learn, observe, exercise their skills through the practices, summaries; to have good attitude towards mathematics; to be creative; to develop their skills and mathematical interpretation; and be able to use in their daily life.
