Draw polygons specified by coordinates in the first quadrant
Lesson details
Learning outcome
I can draw polygons specified by coordinates in the first quadrant.
Key learning points
- The first digit in the coordinate gives the horizontal distance from the origin along the x-axis.
- The second digit in the coordinate gives the vertical distance from the origin along the y-axis.
- Use a ruler to join the points you have plotted to form a polygon.
Keywords
Polygon - A polygon is a 2D shape made up of three or more straight lines.
Vertex / vertices - A vertex is the point where two lines meet. The plural is vertices.
Coordinate - Coordinates are a set of values that show an exact position.
Common misconception
Pupils may mistakenly plot the y-coordinate (vertical distance) first, then the x-coordinate (horizontal distance), leading to incorrect point placement.
Reinforce that the x-coordinate comes first by using mnemonics such as "X before Y, along the ground before you fly." Practice plotting a few points together as a class to build this habit.
Teacher tip
Guide students to follow the sequence of the coordinates carefully, reminding them that the points should be connected in the order given. Encourage them to double-check their sequence before drawing lines.

Assessment exit quiz
6 Questions
Q1.Sofia thinks of a shape for Lucas to draw. She gives him six coordinates to mark the vertices. What shape must it be?
Q2.Write the coordinates of the circled vertex. Remember to write the coordinates using brackets and a comma.
Q3.Sofia wants to draw a rectangle. What is the missing coordinate? Remember to use brackets and a comma.
Q4.Sofia wants to draw a trapezium. Identify the coordinates so that she is able to mark the final vertex.
Q5.Lucas plots out a triangle. He moves the vertex marked at (1, 5) to (3, 4). What shape will it now be?
Q6.Sofia describes a polygon using coordinates to mark the vertices. She gives Lucas exactly 4 coordinates. What shape can it not be?

We use learning cycles to break down learning into key concepts or ideas linked to the learning outcome. Each learning cycle features explanations with checks for understanding and practice tasks with feedback. All of this is found in our slide decks, ready for you to download and edit. The practice tasks are also available as printable worksheets and some lessons have additional materials with extra material you might need for teaching the lesson.
The assessment exit quiz will test your pupils' understanding of the key learning points.
Our video is a tool for planning, showing how other teachers might teach the lesson, offering helpful tips, modelled explanations and inspiration for your own delivery in the classroom. Plus, you can set it as homework or revision for pupils and keep their learning on track by sharing an online pupil version of this lesson.
