Introduction to fractions

 A fraction is part of a whole number.  Think of when you have money.  When you have change in quarters, dimes and nickels, you have part of a dollar.  You don't have the entire dollar.  If you have 2 quarters you have 50 cents, or 1/2 of a dollar.  If you have a birthday cake to share with your 7 friends, we cut the cake into 8 pieces, and you get 1/8 of a cake.  We use fractions everyday with money, measurement, cooking and baking and many other things.

When we compare fractions, we are just looking at which one is bigger. Fractions are a bit more difficult to compare than whole numbers. Watch the video below to learn more about comparing fractions.

After watching the above video click the link below to practice comparing fractions.

Single transformations of 2-D shapes - translations

 A translation is like a slide.  An object slides from one spot to another.  It does not change size, doesn't flip, and doesn't change direction.  It stays exactly the same, sliding from one spot to another.  Think of when you go down a slide on the playground.  The picture below shows examples of translations, or slides.

Watch the video below to see how to translate shapes.

After watching the video, on a piece of paper draw 3 shapes of your choice.  Translate them to a new spot.  Take a picture of your drawing and send it to your teacher!

Single transformations of 2-D shapes - rotations

 When we rotate an image, we turn a shape on a point of rotation.  We can turn or rotate the image clockwise or counterclockwise.  The point of rotation will be on one of the vertices of the shape.

Think about the hands on a clock.  When the minute hand moves from the 12 to the 3, it rotates a quarter turn clockwise.

When the minute hand moves from the 12 to the 6, It rotates a half turn clockwise.

When the minute hand move from the 12 to the 9, it rotates a three-quarter turn.

Now that you have seen how to do rotations, on a piece of paper draw a triangle.  Label the vertices A, B and C.  Rotate the triangle a half turn clockwise, and label the vertices on the image.

Draw a square and label the vertices A, B, C and D.  Rotate the square 3/4 turn clockwise and label the image and its vertices.

Draw a shape (not a circle) of your choice. Choose a vertex to rotate your shape 1/4 turn counterclockwise.  Label your image and the vertices.  

Once you have finished, take a picture and email the picture to your teacher!
