STAGE 2 Grid 2 Numeracy This grid covers our two focus topics: 1. Multiplication and Division 2. Three-Dimensional Space

Parent Note: This grid contains open-ended math problems (marked with a *). Open-ended math problems are problems that have more than one possible answer. These problems might present an end result and then ask students to work backward to figure out how that end result might have been achieved or they might ask students to compare two concepts that can be compared in a variety of different ways. But whatever way they are presented, the purpose of open-ended math problems is always to encourage students to use higher order thinking skills to solve problems and understand that some problems can be solved in many ways, with many outcomes. 1. 3D objects have three dimensions – length, width and depth. Read page 2 of Properties of 3D Shapes. Record a series of clues that describe a 3D object of your choice. You need to write at least five clues. Here are some helpful vocabulary terms: flat surface, curved surface, face, edge and vertex (vertices).

Or Create a 3D objects quiz with at least ten questions. E.g. I have 5 faces and 8 edges. Don’t forget to include the answers.

2. The net of a 3D object is what it looks like if it is opened out flat. A net

can be folded up to make a 3D shape.

Make at least four 3D objects using the nets provided in this link or Activity 2 stencils or take apart

packages at home that are prisms (including cubes) to create 3D shape

nets, eg cut up tissue boxes. Nets Link: https://bit.ly/3dzuWBo

Can you describe any similarities and

differences between the objects?

3. Make this sentence correct in as many ways as you can: *

___ x ___ = ___ x ___

Upload a photo of your work to

seesaw

If you would like to draw groups of items or arrays to support your

learning please include these as well.

4. Would you rather: * 24 50c pieces Or 7 $2 coins Explain your thinking and upload to seesaw or complete on your workbook. What strategies did you use to help solve this problem? E.g. repeated addition, arrays or multiplication?

5. An Array is a way of displaying a multiplication number sentence in columns and rows. * Complete the first page of this link: https://bit.ly/2WXGeIP Make some arrays and show the number sentences that match the arrays. E.g. **** **** 2 x 4 = 8

6.

3D objects have faces, vertices and edges. Do you know where

they are?

View 3D Objects. Pick four of these prisms to draw and label the faces, vertices and

edges: triangular prism, rectangular prism, cube,

pentagonal prism, hexagonal prism or octagonal prism.

7. The answer is 80. *

What could the multiplication question be?

You can use arrays to help you

problem solve.

8.

Use a variety of materials you have at home (blu tack,

playdough, toothpicks or straws) to make models of 3D objects: • make a cube • make a pyramid • make a house (combine

cube and pyramid) • make a tower using

multiple cubes and one pyramid to crown the top

There are examples on Activity 8 stencil.

9.

List at least ten different 3D objects (eg. triangular prism and hexagonal pyramid). Decide on a way to sort the objects and display it in a table. E.g objects with a curved face or

objects with at least 6 edges. Or

Complete the Venn Diagram or activity stencil 9 by sorting some common 3D shapes according to

their properties. Eg. I only have a curved surface.

10. Complete the activity 10 stencil on Multiplication Problem Solving.

1. Write a multiplication

number sentence in the middle equation box.

2. Write the Word problem in the top left

3. Repeated addition number sentence in the top right

4. Draw your groups of items in the bottom left

5. Display your number sentence as an array in the bottom right

11. 3D shapes have faces (sides), edges and vertices (corners). Faces. A face is a flat or curved

surface on a 3D shape. Edges. An edge is where two

faces meet. Vertices. A vertex is a corner

where edges meet.

Complete a Maths Online lesson on 3D objects. You can pick from ‘Geometric Properties of Objects’ or ‘Faces, Vertices and Edges.’

Or Complete the Properties of 3D Shapes Worksheet or on activity 11 stencil by naming 3D objects and counting the number of face, edges and vertices. 16. Complete the times table wheels on activity 16 stencil or using this link

https://bit.ly/2An2KDn Now create one of your own and colour and display somewhere in your house. Upload your work to

seesaw or paste in your book.

12. Would you rather… *

Have 3 pencils that are 9cm each or

5 pencils that are 6cm each?

Explain your thinking and upload to seesaw or complete in your

workbook.

13.5X Table Create a 5x times table chart that could be displayed in a Year 2 classroom E.g. 1 x 6 = 6 2 x 6 = 12

• Make it bright. • Make sure you know your

5 times table. • Get a family member to

test you. Try mixing the order.

Now create a 10 times table chart that could be displayed in your class.

14. 3D objects are the solid shapes you see every day, like boxes, balls, coffee cups, and cans. If you look around you will see items that are made from many different 3D objects.

E.g. Tin foods are cylinders.

How many can you identify? Can you list items that are 3D objects that begin with each letter of the

alphabet? E.g. Apple - sphere

Ball - sphere Candle - cylinder

Dice - cube

15. Make a multiplication chatterbox on your times table of your choice.

See if you know the answer before you lift the chatterbox

flap.

20. Place 6 items that are 3D objects into a bag called a feely bag. Ask someone in your household to describe an item by feeling it and saying "this has a point, there's a circle at the bottom" etc.

Try to use the terms faces, edges and vertices.

Have them guess the item and name the 3D shape.

17. Design a 3D shape poster by sketching or drawing at least two 3D objects from different viewpoints (top, front and side views). One viewpoint may be from above looking down onto the shape from a bird’s eye view. What do you see? You might like use a computer drawing tool. Watch this videos to help you. https://bit.ly/2yEgvgL Or Complete investigate the various viewpoints of 3D objects.

18. The Commutative Property of multiplication means that two numbers can be multiplied in either order and you will still arrive at the same answer. E.g. 3 x 4 = 12 OR 4 x 3 = 12 Activity 18 stencil or use the link

https://bit.ly/2Wwe0pD

Show the Commutative Property of seven multiplication number

sentences. You can use arrays to help you .

19. Draw or construct an animal or house using at least four different 3D shapes. List the 3D shapes that you use.

You could also try to find out:• how they are made;

• how many ordinary packets of crisps a tube of Pringles would fill;

• about other unusual mathematical names for 3D shapes.

Properties of 3D ShapesChallenge3D shapes are shapes which you are able to pick up. They have faces (sides), edges and vertices (corners).

Complete the table below, identifying the different properties each 3D shape has.

An Amazing Fact a DayThe shape of a Pringle is called a hyperbolic paraboloid.
