The grade 8 students in math have been studying simultaneous equations, which are a collection of equations with multiple variables that are solved together to determine the values of those variables. Typically, the solution to a system of equations is a set of values that satisfy all the equations at the same time. The students have been taught two methods for solving these equations: the graphical method, where the equations are graphed on a coordinate plane and the solution is found at the points where the graphs intersect, and the elimination method, where the equations are manipulated by adding or subtracting them to eliminate one variable. This simplifies the system to a reduced set of equations with fewer variables, which can then be solved. Afterwards, the solution is substituted back into the original equations to find the values of the remaining variables. This week, the students had their summative assessment (criteria ABC and D), and once their grades have been recorded, they are looking forward to reviewing and reinforcing their understanding of simultaneous equations.
