## How to plot coordinate pairs song (Password: SI2017)

I found teaching this song with arm movements invaluable to students to help them remember how to plot coordinate pairs.

## Grade 6 - Data Management and Probability:

* Data Management and Probability: *collecting and organizing discrete and continuous data; displaying data using continuous line graphs; selecting appropriate graphical representations; using continuous line graphs and mean to compare sets of data; finding theoretical probabilities; predicting the frequency of an outcome based on the theoretical probability

Overall Expectations

By the end of Grade 6, students will:

• collect and organize discrete or continuous primary data and secondary data and display the data using charts and graphs, including continuous line graphs;

• read, describe, and interpret data, and explain relationships between sets of data;

## Big Ideas In Data Management

1. Graphs are powerful data displays because they quickly reveal a great deal of information

2. To collect useful data it is necessary to decide in advance what source or collection method is appropriate and how to use that source or method effectively.

## Are there other types of graphs?

## Some Definitions

__Coordinate Grid__- A grid with each horizontal and vertical line numbered in order

__Plot__- Locate and draw a point on a coordinate grid

__Coordinate Pair__- A pair of numbers that describe a point where a vertical and horizontal line meet on a coordinate pair

__Origin__- The point on a coordinate grid at which the horizontal and vertical axes meet. The coordinate pair of the origin is (0, 0)

## Discrete And Continuous Data - How are they different? How are they the same?

## Creating a Line Graph

## Hands On

## Can a line graph be used to predict how much water a tap wastes in 7 minutes?

- What type of data is this?
- Create a graph to display your data.
- What type of graph should you choose to display your data? Why?
- Can you use the graph to predict how much water is lost in 5, 6 and 7 minutes.
- Can you use the graph to predict the number of litres of water wasted in 2.5 minutes?

1. What type of data is this?

2. Create a graph to display your data.

3. What type of graph should you choose to display your data?

4. Can you use the graph to predict how far the car can travel in 5s.

5. Use the graph or table to estimate the distance the truck can travel in 3.5s.

## A Beginner's Guide To Graphing Data

While watching please take notes on what makes a proper graph. This will help you when you make your own video on Explain Everything on how to make a proper graph.

## Create Your Own Video

Be sure to include:

- an explanation of your frequency table (what your data is)
- label the X and Y axis
- What is your scale? What do you need to know to create your scale?
- How EXACTLY do you plot information on your graph?

## Mean, Median and Mode

## If the mean of these numbers plus one additional number is 9, what is the missing number?

## Mean, Median and Mode

__Mean__

Mean is the average, the average, the average

Mean is the average,

You add and then divide.

__Mode__

Mode is the most, the most, the most,

Mode is the most,

It’s the number with the most.

__Median__

Median is the middle, the middle, the middle,

Median is the middle,

You have to order first.

## Outlier - What is an Outlier?

## Outliers - A number that is much larger or much smaller in your DATA SET

- If there is an OUTLIER use the median

## What did we learn about mean, median and mode?

–We learned how to interpret mean, median and mode

–Sometimes there are OUTLIER data that skew the results

–Sometimes it is best to take the mean, sometimes the median, sometimes the mode - it depends what you are trying to get from the results
