# Coordinate Plotter

## Instructions

Drag the points below onto their correct positions on the coordinate grid then press the Check button.

Check

### Instructions

This activity provides practice plotting points on a coordinate grid. Drag the coloured circles so that their centres are directly over the labeled coordinates. Click the check button at any time to see if the points you have positioned are correct. There is only a small amount of tolerance and you are expected to be quite accurate (more so with the higher levels). If you would like to be more effective placing the points in exactly the right places use your browser’s zoom facility to enlarge the image to something like 400%.

If you place a point in the wrong position, after clicking the check button you will see a red cross appear. You should then try again, dragging that point to its correct position. Ask your teacher if you get stuck

"Just wanted to let you know that at the start of level 4 I had a problem with placing coordinates beyond 30 because the box holding the coordinates are covering half of the grid.

[Transum: Thanks for your feedback Alaina but the software chooses the coordinates so that they are not in the area covered by that box. Look out for the negative signs.]"

"This looks great for my year 8s' first (remote) lesson on coordinates next week. Just a shame that the box on level 4 covers part of the x axis so they won't be able to see the numbers above 30.

[Transum: Thanks for your feedback Eleanor, much appreciated. The box covering part of the x axis is a deliberate feature designed to challenge pupils to figure out for themselves the x values greater than 30 rather than rely on the axis labels. You will notice that all coordinates with x values greater than 30 have negative y values so they are not obscured by the box. My prediction is that they will be able to figure out a way of overcoming this difficulty. Let me know how they get on.]"

"It's really good but the box keeps on blocking the x-axis but overall I really like, keep doing a great job!"

"Just to report level 2 of this task is unbeatable as the check tab covers up a few coordinates can you please keep this in mind.

[Transum: Thanks for your feedback George. You are not the only person to have mentioned this but I am convinced that the check tab does not get in the way. I have tried the activity on a number of different devices but the check tab does not cover any of the coordinate locations. Could someone please send me a screen shot of what the activity looks like on your computer?]"

## Help

Some people have trouble remembering what the two numbers in a set of coordinates represent. The first number is the x-coordinate and tells you how many units you go across to the right (negative numbers move you to the left). The second number tells you how many to move up (negative numbers move you down).

The following saying helps you remember the order of the coordinates:

Along the corridor then up the stairs.

Don't wait until you have positioned all of the points before you click on the 'Check' button. Click it often as you work through the activity to see if you are doing it correctly.
