recognising 3d shapes from 2d drawings

What is this?

This is the second in a series of three activities. All of these activities are set in the context of a Goggle box show chosen 'Let's Bake'. These activities have been designed to requite children practice in drawing two-dimensional (2d) shapes and make representations of 3D objects using a range of methods and resource.

This learning activity is intended to back up teachers to plan learning experiences for children in their usual setting or while they are learning at dwelling house. Too as taking business relationship of national and local guidance relating to Covid-xix, the activity should be used or adjusted accordingly to consider the range of learners and their prior cognition and private circumstances in relation to this learning experience.

Curriculum for Excellence (CfE) experiences and outcomes: Second level

Numeracy and Mathematics

• I tin draw 2d shapes and brand representations of 3D objects using a range of methods and efficient employ of resources. MTH ii-16c

Technology

• I can extend and heighten my design skills to solve problems and can construct models. TCH 2-09a
• I can employ a range of graphic techniques, manually and digitally, to communicate ideas, concepts or products, experimenting with the use of shape, color and texture to enhance my work. TCH 2-11a

Purpose of the activity

This activity has been designed to give children practice in drawing 3D objects.

Additional data and resources to support this action can exist accessed using the links shown below.

• What are the properties of 3D shapes? - BBC Bitesize
  
• 3D shapes - BBC Bitesize
• 3D shapes - Teaching Ideas
• From mind to design in minutes - Tinkercad (This can exist accessed using a Glow Google login.

This activity can be used in class or adjusted for learners who may be working remotely.

Learning activity

• Mario is taking part in a televised blistering competition chosen 'Let'south Bake'. He has to design and bake a cake that meets all of the criteria shown below.
• Before yous get-go the activity, read the criteria and cheque that yous empathise the meaning of all of the words in bold.
• Look at Mario'due south design for the block. Does it include all of the required features? Explicate your respond.
• Create a different design for the block that incorporates all of the required features.

  	Description of Required Features
  Size	four layers
  Shape	two layers must be cylindrical. 2 layers must exist cuboid shaped.
  Height	Each layer must be 50% shorter in acme than the previous layer. Total height must not exceed sixty cm.

  

Extension activity

• Create a set of criteria for a cake design and and then construct a model of the block. You could use empty cardboard packaging or other household items to build your model.
• Create the criteria for some other cake pattern. Ask someone else to produce a drawing or a model of the cake, based on the description that you accept provided.

National benchmarks

Numeracy and Mathematics

• Describes 3D objects and 2d shapes using specific vocabulary including regular, irregular, diagonal, radius, diameter and circumference. Applies this knowledge to demonstrate understanding of the relationship between 3D objects and their nets.
• Uses digital technologies and mathematical instruments to draw 2d shapes and make representations of 3D objects, understanding that not all parts of the 3D object can be seen.

Technologies

• Estimates and then measures accurately using appropriate units and tools.
• Creates a range of ideas and chooses a suitable solution.
• Evaluates solutions and explains why they are or are not suitable.
• Sketches geometric shapes to create objects.
• Draws geometric shapes accurately.
• Sketches 2D and 3D drawings of objects.

Possible approach to assessing learning

• Encourage the children to evaluate each other's designs. Are they able to identify if fundamental features have been included? This will give you evidence of their ability to assess a blueprint using a set criteria.
• When completing the extension activity, are the children able to include relevant information and evaluate designs based on the criteria provided? This volition help you to assess the depth of their understanding and their ability to transfer and utilise their knowledge.
• Ask the children to explain how they reached their last design. Tin can they show their initial sketches and explain how they adapted these to see the criteria? This will help y'all to assess if they can evaluate solutions and explain why they are or are not suitable
• Encourage the children to observe and talk over their drawings. Use questioning to assess whether they empathise that 2d sketches of 3D objects are representations and may not always be drawn to scale i.eastward. you may exist able to measure the front face of a cuboid using a ruler but the sides may not exist drawn to scale.

You know your learners well and can alter the expectations of outcomes for individuals in line with the Benchmarks.

When planning your arroyo to assessing learning, delight take account of the latest guidance on assessment approaches.
