Students learn to use ratios and proportions to solve real world problems involving models and drawings.
In this lesson students learn to model a real-life situation by collecting data from a few trials, graphing the data, and then drawing a line of best fit that can be used to make predictions.
Students will be able to model how the changes of a figure in such dimensions as length, width, height, or radius affect other measurements such as perimeter, area, surface area, or volume.
Students will be able to have a better understanding of the slope of a line, the y intercept, and parallel lines.
Students produce a scatter plot that compares the estimated ages to actual ages od famous people. They will also determine the equation of a line that represents estimates that are 100% accurate and what it means for a point to fall above or below the line.
Students learn to model a real-life situation by collecting data from a few trials, graphing the data, and then drawing a curve of best fit. The student must decide which of the equations best fits his/her data.
Students learn how to gather information about a large population based on a representative sample whose makeup is similar.
Students see that equations of vertical and horizontal lines are parallel to the axes. Additionally, they see that points on both lines represent the point of intersecton and if there is no point of intersection, the lines are parallel.
Students practice with pictorial representations and make connections to the abstract concepts and procedural skills of adding and subtracting integers.
Students will learn that some transformations, such as reflections and rotations, do not change the figure itself, only its position or orientation.
