Marie uses a given equation and interprets it as a graph. She understands how the slope of the line is determined in some simple examples. Additionally, she does well in first identifying all whole number coordinates that the line passes through.

Marie could practice a lot more in sketching lines as sketching graphs is a very important skill in the later years of high school. Furthermore, she could make better use of a grid when sketching, but not overuse it as it may not be provides in an exam.

Marie could identify the gradient and y-intercept for each line given the gradient intercept form and explain how to calculate the gradient. She used rise over run to determine whether a line is steep or shallow, while also determining whether the line is increasing or decreasing.

Marie needs some improvement in describing what the gradient and y-intercept represents in a worded problem. She should work on converting general form of a line into the gradient intercept form, and vice versa.

Marie practically did her own assignment without much help. It is very responsible of her to start an assignment early. She also did well for the simple interest part and applying multiple discounts.

Marie should work on understanding compound interest and compare the differences between it and simple interest. During the assignment, I'd highly recommend that she label her answers and answer the question in a concluding statement to avoid losing any marks.

Marie started slow, but quickly grasps the calculations and even challenged herself to memorise the numbers in ATO tax brackets. She uses a variety of tools to imagine how tax can be reduced.

Marie did well for most of the lesson but she just needs to watch out for silly errors when copying numbers into the book or punching numbers into a calculator correctly.
