drawing 2d representations of 3d shapes

What is this?

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

This learning activity is intended to support teachers to program learning experiences for children in their usual setting or while they are learning at habitation. Also every bit taking account of national and local guidance relating to Covid-19, the activity should exist used or adapted appropriately to consider the range of learners and their prior knowledge and individual circumstances in relation to this learning experience.

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

Numeracy and Mathematics

• I can describe 2d shapes and make representations of 3D objects using a range of methods and efficient use of resources. MTH 2-16c

Technology

• I can extend and raise my blueprint skills to solve issues and can construct models. TCH 2-09a
• I tin can utilize a range of graphic techniques, manually and digitally, to communicate ideas, concepts or products, experimenting with the utilize 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 cartoon 3D objects.

Additional information and resources to back up this activeness tin can exist accessed using the links shown below.

• From mind to blueprint in minutes - Tinkercad (This tin can be accessed using a Glow Google login.

This activity tin can exist used in class or adapted for learners who may be working remotely.

Learning activity

• Mario is taking function in a televised baking competition called 'Let's Bake'. He has to design and bake a cake that meets all of the criteria shown below.
• Before you start the activity, read the criteria and check that you lot sympathise the meaning of all of the words in assuming.
• Look at Mario's design for the cake. Does it include all of the required features? Explain your respond.
• Create a different design for the cake that incorporates all of the required features.

  	Description of Required Features
  Size	4 layers
  Shape	2 layers must exist cylindrical. 2 layers must be cuboid shaped.
  Height	Each layer must be 50% shorter in height than the previous layer. Full tiptop must not exceed 60 cm.

  

Extension activity

• Create a fix of criteria for a block blueprint and and so construct a model of the block. Yous could utilize empty paper-thin packaging or other household items to build your model.
• Create the criteria for some other cake design. Ask someone else to produce a cartoon or a model of the cake, based on the description that you lot have 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 cognition to demonstrate understanding of the relationship between 3D objects and their nets.
• Uses digital technologies and mathematical instruments to draw 2D shapes and brand representations of 3D objects, understanding that not all parts of the 3D object tin be seen.

Technologies

• Estimates so measures accurately using advisable 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'southward designs. Are they able to place if fundamental features have been included? This will give you lot testify of their ability to assess a blueprint using a ready criteria.
• When completing the extension activity, are the children able to include relevant data and evaluate designs based on the criteria provided? This will help y'all to assess the depth of their understanding and their power to transfer and use their knowledge.
• Ask the children to explicate how they reached their final design. Tin they show their initial sketches and explain how they adapted these to meet the criteria? This will assistance you to assess if they can evaluate solutions and explain why they are or are non suitable
• Encourage the children to observe and discuss their drawings. Use questioning to assess whether they understand that second sketches of 3D objects are representations and may not always be fatigued to scale i.eastward. you may be able to measure the front face up 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 approach to assessing learning, please accept account of the latest guidance on cess approaches.
