Math Centers 10.4

Learning Objective:  I will understand timezones and 
how they work.

Last night in homework you learned a little bit about time zones and how they work.  Now you are going to do a couple of activities to see how well you remember what you learned!

First,  READ THIS:

The rotation of the planet means that we can't have just one time zone for the whole world. If that were the case, then noon would be the middle of the day in some places, the evening in other places, and the middle of the night somewhere else. In some places, the Sun would go down at 7 p.m., but that same hour thousands of miles to the east would be the time the Sun was rising.

(If you are interested, you can read even more about timezones by CLICKING HERE)

Second, CLICK HERE to look at The World Clock and see different times in the world right now.  It's pretty fascinating stuff! :)

Third, CLICK HERE to take a 10 question quiz about timezones.  Good luck!!!

Exploring Networks

Topic 9.5

Learning Objective:  I will understand traversable networks. 

Key Vocabulary-

network:  a diagram consisting of arcs (branches) connecting points or nodes (junctions).  A network may represent a real-world situation, such as a road system or electronic circuit.  Sometimes the nodes are called vertices.

traverse the network:  the process of tracing each path of a network without going back over any path a second time. 

Look at the bus route below.  This is an example of a network.  Engineers and designers work together to form the best and most economic way for a bus to travel.  


Definition of a Traversable Network
(For original post by Passy's World of Mathematics, CLICK HERE)
 
A “Traversable Network” is one where we can find a route through the network, along the edges, that uses all of the edges only once.

A network is said to be traversable when it is possible to start at a “Vertex” (or “Node”), and trace out the whole network without having to retrace over any of the connector “Edges”.

The following is a Traversable Network, because we can easily get around the Network traveling along each Edge (or connector) only once.

Now watch the video about traversable networks:



Are these shapes traversable? Remember if you can traverse the network, you will go across each path without going back over any path a second time.

Vocabulary 3.4

Here are your vocabulary words for the week!

Creating Symmetrical Designs

Topic 9.4

Learning Objective:  I will create 2-dimensional designs that have either line symmetry or rotational symmetry.  




In your notes on your iPad, answer the following questions (email them to Mrs. Simonson when you are done.):

  1. Does the figure above have rotational symmetry?
  2. Explain how you know.
  3. Explain what rotational symmetry is.

Now watch this short video on line symmetry:

Rotational Symmetry

Topic 9.3

Learning Objective:  I will identify and describe rotational symmetry in 2-dimentional shapes.  


 Rotational Symmetry


Rotational Symmetry
With Rotational Symmetry, the shape or image can be rotated some amount and it still looks the same.

This image can be rotated to three different positions and it would look the same.
Watch the two short videos below to help you better understand rotational symmetry.

Now CLICK HERE  and then CLICK HERE to go and play some symmetry games.

Reviewing Transformations and Symmetry

Topic 9.2

Learning Objective:  I will understand flips, slides, and turns for 2-d shapes and I will draw lines for symmetry.

 
 Listen to this song about transformations:
 


Did you like his accent? I did! Now watch this video to help you to review symmetry:




Now GO HERE and play Icy Slides, Flips and Turns.

Weathering and Erosion

This week we are starting our unit on Earth's Surface.  There are a few things you need to know to get you started. Here are a FEW of the key vocabulary words that you are going to want to know for this unit.


Now watch this video about Weathering, Erosion, and Deposition:
