Drawing 3D Objects
Draw two-dimensional representations of three-dimensional objects
The photograph shows a cube made from 7 smaller green cubes and one smaller
red cube. Using no more than lines can you draw a two-dimensional
representation what the shape looks like after the blue cube has been removed.
The top left vertex of the shape should be where the red flashing dot is.
Try your best to answer the questions above. Type your answers into the boxes provided leaving no spaces. As you work through the exercise regularly click the "check" button. If you have any wrong answers, do your best to do corrections but if there is anything you don't understand, please ask your teacher for help.
When you have got all of the questions correct you may want to print out this page and paste it into your exercise book. If you keep your work in an ePortfolio you could take a screen shot of your answers and paste that into your Maths file.
Mathematicians are not the people who find Maths easy; they are the people who enjoy how mystifying, puzzling and hard it is. Are you a mathematician?

"I think that having a starter of the day helps improve maths in general. My pupils say they love them!!!"

"I use Starter of the Day as a registration and warm-up activity for my Year 6 class. The range of questioning provided is excellent as are some of the images.
Each month a newsletter is published containing details of the new additions to the Transum website and a new puzzle of the month.
The newsletter is then duplicated as a podcast which is available on the major delivery networks. You can listen to the podcast while you are commuting, exercising or relaxing.
There are answers to this exercise but they are available in this space to teachers, tutors and parents who have logged in to their Transum subscription on this computer.
A Transum subscription unlocks the answers to the online exercises, quizzes and puzzles. It also provides the teacher with access to quality external links on each of the Transum Topic pages and the facility to add to the collection themselves.
Subscribers can manage class lists, lesson plans and assessment data in the Class Admin application and have access to reports of the Transum Trophies earned by class members.

Learning and understanding Mathematics, at every level, requires learner engagement. Mathematics is not a spectator sport. Sometimes traditional teaching fails to actively involve students. One way to address the problem is through the use of interactive activities and this web site provides many of those. The Go Maths page is an alphabetical list of free activities designed for students in Secondary/High school.
Are you looking for something specific? An exercise to supplement the topic you are studying at school at the moment perhaps. Navigate using our Maths Map to find exercises, puzzles and Maths lesson starters grouped by topic.

Try! - Practise drawing three-dimension objects on the isometric dots here.
Level 1 - Complete the drawings of the letters to make them look three-dimensional
Level 2 - Draw a two-dimensional representation of a model made from plastic cubes
Level 3 - Draw a two-dimensional representation of a larger model made from plastic cubes
Level 4 - Draw a two-dimensional representation of a model after one cube has been removed
Level 5 - Draw a two-dimensional representation of a model after one cube has been added
Level 6 - Draw all the different ways that four cubes could be arranged
Exam Style Questions - A collection of GCSE style problems related to the statement: "Pupils should be taught to construct and interpret plans and elevations of 3D shapes".

The Level 4 challenge is to complete the task using only lines. If you do you will be awarded a Transum virtual trophy.
Click a start point and then click an end point. A straight line will be drawn between those two points.
You can click the 'Check' button when you think your drawing is complete (remember you must have used lines.).
If you make a mistake you can use the 'Undo' and 'Clear' buttons. Great concentration is required!
You can use the Try! page to experiment, explore and investigate - Practise drawing three-dimension objects on the isometric dots before starting the challenges.
For each of the challenges you are only allowed to use a fixed number of lines so you don't want to waste any!
If you want to join A and B do it with one line joining A and B not three smaller lines from dot to dot.
