God showed us that He is a Master Designer when He created the world. Instead of making everything the same, He did much more by introducing lots of shapes and colours to make our world interesting and beautiful for us. (This concept was discussed in the Let's Celebrate Biblical Studies unit).
Have a go at solving the two problems below.
The "Odd One Out" has several different answers - see how many you can find.
The problem about the cone has only one correct answer.
Watch this with the sound off. Start past the advertising.
Now play some games that your teacher will give you.
Here are two simple problems. Just remember to read and think carefully. There is only ONE correct answer for each.
Complete this activity on Seesaw. You will need to drag each of the shapes into the correct column.
When you have finished click carefully through this presentation, thinking about your answers to the questions.
There are six sections to complete and they are listed in the white column on the lefthand side of the screen.
Which one doesn't belong? Try to give an explanation for each shape.
Make as many different statements about what you learn from this table without using any of the numbers in the chart!
Watch this video about how we describe 3D shapes, and then check out the images below to remind you about 3D shapes.
Questions
Look at the shapes above and answer these questions.
Which of these shapes is a 3D object with no flat surfaces?
Which is a 3D object that can roll?
Which is a 3D object with flat and round surfaces?
Which is a 3D object that cannot roll?
Complete the following activity in Seesaw.
Work out your answer to each of the problems below - there is only one correct answer for each.
Complete this activity in Seesaw.
Remember that we describe 3D objects by how many faces it has, how many edges and how many vertices (corners) it has.
Complete this worksheet by naming each object and counting the number of faces, edges and vertices (corners) it has.
Then complete the second worksheet by colouring in the shapes that you would find in each object. Look very carefully or you will be tricked!
A simple problem below - but can you be sure you have found all the possible answers? Explain how you know.
To revise what we have been learning about 3D objects, your teacher will give you some of these worksheets to complete.
Here is another challenge. Think carefully and don't be tricked!
Use the camera on your iPad to take photos of different 3D objects.
Then go into Keynote and see if you can make a chart with 3 columns.
Give each one a heading: prisms with straight edges, cylinders, pyramids.
Then insert your photos in the correct columns.
Try to find 10 different ways of balancing this number sentence. You could also change the sign from + to something else!
Watch the following video clip about what 3D objects look like if they are flattened out. Then complete the worksheet.
Have a go at the problem below. Read it carefully and each time you think you have come up with a solution, check that it matches all the instructions.
You will complete an assessment on 2D and 3D Space.
Your job today is to design a suburb for downtown of a city. You will be given a piece of paper on which to design what buildings you want to be in your suburb. Have a look at some of these pictures and think about what shapes many buildings are in Sydney, or any other large city. All buildings are 3D shapes.
Here are some examples of what students have created. Have a careful look at them to get some ideas. Then design your own on the paper given to you.
To get the shapes you want, some buildings can be made of two 3D shapes on top of each other. You need to think of roads and parks and what buildings are found there.
Start by brainstorming all the buildings and other features that can be found in a city.
Now, working with a partner decide which ones you want in your suburb.
Sketch out the design for your suburb like the ones above and think about what shape you want each of your buildings to be.
Working together with your partner, each of you needs to cut out the relevant nets and colour them.
Then fold on the solid lines, glue the tabs (surrounded by dotted lines) and create your 3D shapes. Gluing them together can be quite challenging - you will need to take your time and show perseverance.
When you have created all your buildings, position them on a blank background and colour in any roads, parks etc.
Then you can place all the class's different plans together to make up a whole city.
Take photographs of your work and upload it to Seesaw.
