Workbook: 5B
Chapter: 10 Position and Movement
Lesson: 1 and 2 Naming and Plotting Points, Describing Translations
A coordinate is shown using two values, separated by a comma with brackets around them.The values show the position on the x axis (horizontal line) and y axis (vertical line).
A coordinate represents the exact position of a point .
Here are some helpful videos:
BBC Bitesize: Co-ordinates on a grid
BBC Bitesize: What are coordinates?
Please watch both videos which clearly explain what coordinates are.
Now, have a look at the problem below:
I think the x coordinate for A is 4 ½.
What would the y coordinate be?
The y coordinate would be 8 because point A is on the line that leads to 8 on the y axis. How would we write these coordinates?
Carefully look at the working out here:
Now, look at what happens when we are asked to write the coordinates of the vertices of a quadrilateral shape.
Quadrilaterals have 4 sides and their internal angles add up to 360°.
Square, rectangle, rhombus, parallelogram, kite and trapezium are all quadrilaterals.
Revisit quadrilaterals here: BBC Bitesize: How to identify different polygons.
Reminder: A polygon is any 2-dimensional shape formed with straight lines. Triangles, quadrilaterals, pentagons, and hexagons are all examples of polygons. The name tells you how many sides the shape has. For example, a triangle has three sides, and a quadrilateral has four sides. So, any shape that can be drawn by connecting three straight lines is called a triangle, and any shape that can be drawn by connecting four straight lines is called a quadrilateral.
We then have to plot various points from given coordinates and identify symmetrical shapes.

Lesson 2: Describing Translations
Shapes can be transformed in a number of ways. These include translation, rotation and reflection.
Translation causes a shape to move.
Please watch these useful videos:
BBC Bitesize: Shapes and Movement
BBC Bitesize: Position and Direction
BBC Bitesize: What are translation, rotation and reflection?
I’m aware that the last video is a KS3 one but I think the video is great and will be useful!
Here is an example of how to work out a translation problem in MNP:
Good luck with today’s worksheets.
IF YOU NEED SUPPORT: Use a ruler to guide you along the line from the point to the x and y axes.

Marking your answers
As you and your parents now have access to Maths No Problem, I will continue to set daily worksheets for you to complete at home. They may be worksheets that you may have already attempted in class but that’s okay! It’s important that you revise and practise your skills.
You do not need to print these worksheets out – you can simply using your yellow books to show your working out and write your answers. You or your parents can then mark it as you now have access to the answers. Therefore you will not be required to write your answer in the blog comments section as before. Please do comment if you need help or have any questions about the task. Also, please read each other’s comments and help each other out! It is important we stay in touch and talk to each other about maths using mathematical language just like we did in the classroom.
Good luck!

Hello everyone!
I hope you all had a lovely bank holiday weekend – good luck with your Maths No Problem work sheets today!
A little tip that helps me remember which axis comes first when plotting coordinates is…
1) X = along the corridor
2) Y = up the stairs
Thank you for this tip Ms Robertson!
Hello everyone! I hope that you have had a great day so far! I am struggling with the questions on page 78. I am not really sure what to do…
Can someone explain it to me?
Nika??
Hi Nika, all you have to do is look at the plotting on the page before (77) and imagine what other points are needed to finish the shape so it becomes a polygon. So the coordinates of point F would be (9, 3 1/2). This would be a hexagon 🙂 Hope that helps!
Hello Mrs Avdiu! I got the answer 9,4 when I worked it out…
Oh, probably because I didn’t measure it right!
???????????????
~ Nika ???
That’s okay, you were close enough!
Hello again, I am really confused ? on one of the questions…
It asks ‘What shape is the polygon?’
Then it says a completely different shape…
That’s what confuses me a lot….
~ Nika
Hi Nika, A polygon is ANY 2-dimensional shape formed with straight lines. Triangles, quadrilaterals, pentagons, and hexagons are all examples of polygons. The name tells you how many sides the shape has. For example, a triangle has three sides, and a quadrilateral has four sides. So, any shape that can be drawn by connecting three straight lines is called a triangle, and any shape that can be drawn by connecting four straight lines is called a quadrilateral. If it asking you what the shape of the polygon is then you have to say the name of the shape. Polygon is not a name of a shape.
Notice how all the shapes are drawn with only straight lines? This is what makes a polygon. If the shape had curves or didn’t fully connect, then it can’t be called a polygon.
Hello everyone!
I have completed the MNP without any problems and I am fairly confident with it.
Have a great day!
Fantastic!
That’s okay, you were close enough!
Hello everyone!
I hope you are all keeping okay!
I have done these worksheets and I found them okay!!
I marked these and only got 2 wrong altogether! 😀
Have a lovely day everyone!! 🙂 😀
Kayla 😀 😀 😀
Super!
Hello everyone, I was meant to post this morning but the website would not open so I am posting now. I did the worksheets and found them alright and I was confident.
I think you were not the only one experiencing problems! Thank you for sharing. Glad you found them okay.
Hi Mrs Avdiu, Regan and Erin have completed today’s maths work.
Well done! How did you find it, girls?
