Game: PONG

Aim: Break the bricks, score points

Method:
Use your mouse or tap in the white bar to move the paddle horizontally to bounce the ball up the screen. Answer questions when you break the white bricks, score big points with the yellow bricks.

Your final score is based on correct answers, bricks broken and time taken.

Line of best fit

# PONG game to practice'Line of best fit' for 8th grade

### Scatter graphs: line of best fit

Scatter graphs use points to represent values that correlate the relationship between two variables. The scatter graph will indicate the degree to which the two variables are correlated (linked or related). If the variables are correlated, you will be able to draw a line of best fit. The more strongly two variables are correlated, the more closely the points will intersect the line of best fit. We are mainly concerned with linear correlation in this topic - the line of best fit is a straight line.

Drawing lines of best fit involves trying to pass the straight line through as many points as possible, with the remaining points being evenly distritbuted above and below the line.

One of the benefits of being able to draw a line of best fit is that it enables us to predict values for one of the variables that we don't have a data point for.

In this topic you are asked to decide which of the given lines is the best fit for the data points provided. The lines are labelled as A, B and C. We have included a few curved lines too.

With our Pong math game you will be practicing the topic "Line of best fit" from 8th grade / Statistics / Two variables / Two variables. The math in this game consists of 16 questions that ask you to identify which of the lines is closest to being a line of best fit for the data.

This is our version of the classic early computer game "Breakout" (itself a development of the even earlier "Pong" game - we prefer that name) where a player controls a bar that knocks a ball or puck around the screen.

In our version of Pong/Breakout, there are 3 types of bricks for you to break: green bricks are worth just 2 points; yellow bricks are worth a whopping 50 points; breaking white bricks, which are worth 10 points, wins you a math question from the topic you have chosen.

You start with 5 lives. If the ball goes below the paddle, you lose a life and 200 points. The game ends when you answer all 10 questions or lose all your lives.

### Notes

1. This version of Pong is a one player game to learn or revise math
2. Our PONG for math is a scoring game - play a few times and set a personal best score!
3. Addictive! You may end up trying to avoid the white bricks so that you can play for longer...
