Identify 2D shapes from diagrams
This topic helps you learn the names of many 2-dimensional shapes. We can divide shapes based on the number of sides they have, how many of those sides are parallel, and the nature of the angles where those sides meet. This topic also includes ellipses and circles. Some of the shapes are described below
- A parallelogram is a quadrilateral (4 sides) with opposite sides parallel and equal in length, and pairs of angles are equal.
- A rhombus is a type of parallelogram with all 4 sides equal in length.
- A rectangle is a special parallelogram where all 4 angles are 90°.
- A square is a special type of rectangle where all sides are the same length.
- A trapezoid is a quadrilateral with one pair of parallel sides.
- A kite is a quadrilateral with two pairs of adjacent sides equal in length.
- A pentagon has 5 sides.
- A hexagon has 6 sides.
- A heptagon has 7 sides.
- An octagon has 8 sides.
This topic shows you diagrams of different 2D shapes and you have to name them correctly. You may have noticed that the rhombus is a special type of parallelogram where all 4 sides are the same length. This is true for a few of the shapes in this toic. You should always go with the most specific name, so if it is a rhombus go with rhombus even though parallelogram is also technically correct.
With these interactive math lessons you will be learning "2D shapes: name from diagram" from

'2D shapes: name from diagram' for 3rd grade
Introduction to the math topic
You start the tutorial with a lesson that introduces the math you will be learning. You will see a set of questions one at a time, and for each question you will see the written answer and also hear the answer to that question.
Repeat the question/answer by clicking on the brown speaker sign. Repeat the question/answer and expand the question graphic by clicking on the question box. Move between questions using the arrow buttons below the question. If there is additional information available for your chosen topic, the "i" button on the left upright bar will be brown on white. Click on the button to load the additional lesson information into the main interface.
Either / Or math lesson
This lesson moves on from the "Introduction" lesson and offers you two possible answers to each question. So, you will see a question then a voice will ask "Is this ... or is it ..." and you will have to choose which of the answers is the one that matches the question.
You choose an answer by clicking or tapping on one of the two answer boxes below the question. You can play the audio for each answer again by clicking on the speaker icon beside the written answer (if robot speech is available and enabled). The program will let you know each time whether you answered correctly. A star will light up red for a wrong answer or white/black for a correct answer.
This lesson asks you the questions in a random order compared to the introduction. At the end of the lesson, you can choose whether to repeat the lesson or move on to the next one.
What is it? math lesson
The final lesson of the tutorial shows you multiple possible answers for each question - you must choose the correct one. You are asked a question and below it are a list of two, three, or four possible written/numeric answers from this topic. Pressing the speaker icon will play the math audio for that answer.
For each picture, click on the answer that matches the question. The program will tell you whether you are right or not. As with the Either / Or activity a system of stars indicate your right and wrong answers. The What is it? lesson will show you all the questions you learned in the Introduction but in a random order.
When you complete the "What is it?" lesson, you can choose whether to go on to play some games with this topic, or whether you want to repeat some or all of the lesson activities in this tutorial. You should expect to get 80% of the answers correct in most of the activities before trying some of the Math games with this topic.
