The students in Five White are learning about two-dimensional space. So far we have learnt about the different types of triangles, quadrilaterals and irregular and regularpolygons.

Triangles

Right-angled triangles have one right angle of 90°.

Isosceles triangles have two equal sides and two equal angles.

Equilateral triangles have three equal sides and three equal angles.

Scalene triangles have three sides that are all different lengths.

Quadrilateral means ‘four sides’, therefore any four sided shape is a quadrilateral.

A rectangle is a four sided shape where every angle is a right angle and opposite sides are parallel and of equal length.

A rhombus is a four sided shape where all sides have equal length, opposite sides are parallel and opposite angles are equal.

A square is a four sided shape that has four equal sides, every angle is 90° and all opposite sides are parallel.

A parallelogram is a four sided shape with all sides parallel and equal in length and opposite angles are equal.

A polygon is a plane shape (flat shape) with three or more straight sides. E.g. a triangle, hexagon and pentagon.

Regular polygons have equal sides and angles.

Irregular polygons do not have sides that are all equal in length and/or at least one angle is different in size from the other angles.

The students used the ‘Show Me’ app, cards and computers to practise drawing and explaining the different triangles, quadrilaterals, irregular and regular polygons. Take a look at the videos and the slideshow below.

Click here, here and here for links to videos about triangles and polygons.

Leave a ‘what am I?’ comment for someone to answer about a triangle, quadrilateral, irregular or regular polygon.

E.g. What am I? I have three sides and they are all different lengths.

Awesome videos! All those videos helped me learn more about 2D shapes. Here is my ”what am I?” question : I have 3 sides that have equal sides and angles.

To be honest for the pre test about shapes i did not get one bit. Now im starting to get it! Here is my quesstion to you:
What am I?
-all my sides are equal
-my opposite sides are parallel to each other
-i have 4 sides
-unlike a square the sides are NOT 90 degree angles
What am I?
Can you guess what shape I am?

I have to agree with Andrea I didn`t get one bit of the pre-test but now that I have learnt much more about triangles, quadrilateral and polygons I think I will do much better in the post-test than the pre-test. This is my who am I- I have two straight sides and two equal angles and I am not a polygon or a quadrilateral. Who am I?

those videos helped me heaps! I know that five white have been trying really hard so I am sure they will do good in the test.
WHO AM I ???
– I am a quadrilateral
– I have 4 sides and angles
– I have a 90 degree angle
– I am NOT a polygon
– I am a ____________

I think I have learnt many things and I know so much now.
Who Am I??
-I have 2 sides that are equal lengths
-the other side is a different length
What Am I??

Dear 5W and Miss Azzopardi,
I have learnt a lot about 2D Space. Using the knowledge I used for 2D space I came up with one what am i question:
-I am an irregular quadrilateral
-I have one right angle
-I am shaped like an L
What am I???

I have learnt a lot during maths. Here is a Who Am I?
Who Am I?
-I have 4 equal sides
-My angles are all equal
-I am a regular shape
-I am a quadrilateral shape
Who Am I?

To be honest with you when we first started 2D space I didn’t know much about it. But ever since miss Azzopardi started teaching us i have learnt a lot. Watch:
*I am a Quadalatriel
*I Have Four sides
*I was a square but I got hit by a bus
*I have four equal sides
*Opposite sides are Parallel
WHO AM I???

I have been enjoying leaning about 2d space a lot. i have learnt about polygons, quadrilaterals, circles, triangles and more. I have 3 sides and one angle that is 90 degrees, what am i ?

this maths session is worth it to be honest last year i did not get one bit by now i know how to draw them the rap Bella and Grace made was awesome
i’d love to see more raps on this!!
What am i? i have 2 sides that are equal and one side different

Dear Five White & Miss Azzopardi,

Awesome videos! All those videos helped me learn more about 2D shapes. Here is my ”what am I?” question : I have 3 sides that have equal sides and angles.

Thanks,

Cecilia 🙂

Dear Cicilia,

Yeah those videos are awesome they helped me as well! Is your shape a qualateral trangle?

Sincerly,

Andrea

Dear Andrea,

Sorry! It isn’t a Quadrilateral triangle it’s a Equilateral triangle. Better Luck next time! It was a fun game though.

Thanks!

Cecilia 😉

Dear Cecilia,

Are you an equilateral triangle??

See you later,

Jennifer.A

Dear Jennifer A,

Thanks for replying! Congratulations you are correct. xD

Sincerely,

Cecilia

Dear Andrea,

I knew things in the test but like you I didn’t that much and is your shape a rhombus.

Sincerely,

Jennifer.A

Hi Andrea,

Is your shape a Rhombus

Great,

Josephine

Dear Andrea,

Is your shape a Rhombus?

In class I saw you working so hard! Hope you can keep up the great work!

See you Tomorrow!

Cecilia

Dear Cicilia,

Yes my shape is a rhombus! That shows me that you focus really hard in school.

Sincerly,

Andrea
