Objectives 


Students learn to recognize expressions, equations and inequalities. They solve equations with one variable based on sum, difference, product, and quotient. They translate word problems into equations with one variable and solve for the unknow variable.
Students further strengthen their understanding of twodimensional shapes and solid figures. Among other topics, they are introduced to rotational symmetry and mathematical terminology related to geometric transformations.
Students continue to improve their understanding of various units of measurement and use those skills to solve interesting problems.
Students learn to organize data into histogram, frequency chart and stem and leaf chart.
Students solve equations with two variable based on sum, difference, product and quotient. They translate word problems in to equations with one variable and solve for the unknown variables.
Students are introduced to lines, line segemnts, rays, and angles. They recognize angles as geometric shapes and understand concepts of angle measurement and classification. They apply this knowledge to classify triangles and quadrilaterals.
Students learn to relationship between different units of time. They learn to convert among different units. They apply their skills of addition and subtraction to solve problems related to patterns in time sequences, events on a timeline and schedules described as a timetable.
Students learn to calculate mode, median, mean, and range of data sets. They also learn to compare two data sets using data statistics.
Students are introduced to a coordinate system. They learn about axes, points as ordered pairs of numbers, and origin. They uderstand that the first number of the point indicate how far to travel from origin in the direction of one axis, and similarly for the second number. They join points in straight lines and recognize resulting geometric shapes.
Students learn to enumerate all possible outcomes of an event and calculate probability of simple events.
Students continue learning more about perimeter and area. They are also introduced to the concept of volume of rectangular prisms.
