Presentation on theme: "Geometry and Patterning"— Presentation transcript:
1Geometry and Patterning with Mary and MelodyIn this program you will see some pink smiley faces. Whenyou see one you should take off your headset and work withyour partner on your worksheet. Each page will have oneor more buttons like the blue arrow to the right. Thesebuttons will take you to other pages that will teach youabout Geometry!
2Shapes and Patterns Some shapes that we know: CircleSquareTriangleDiamondOvalRectangleAll of these shapes and many more can be used to form patterns.Take a minute to talk to your partner about what apattern looks like and how they are made.
3- A pattern is a series of objects that are repeated in the same way. Here are examples of patterns:Can you see the pattern below?Find the patterns with your partner.Then draw the next five shapes for each.
4Complete this Pattern circle rectangle triangle Choose the next shape by clicking on a dark blue button.circlerectangletriangle
5Go back and re-read the question. There is a better choice. Try again
11Patterns are all around us! There are so many things that can be made into patterns.Talk with your partner and think of at least five unusualthings that you can use to create patterns.TO READ OUR IDEASCLICK HEREPatterns can also fill large spaces, they do not have to be in a straight line!
13Geometry and Patterning Terms SLIDETURNFLIPSYMMETRYI’m done learningthese terms!
14SLIDE Watch the car slide across the screen! Why is this a slide? original carWhy is this a slide?In this case the car has moved forward. It hasstayed the same size and shape and also facesthe same direction as the original car.Back toMain Menu
15Tessellations in ArtSome artists tessellate complex objects in their artwork!Artists tessellate objects likethis butterfly by using the slides,turns and flips that you learnedabout earlier. The butterfly inthis picture is also symmetrical!Now that you know all about thiscool word, tessellation, you shouldask Mrs. Ferrington to add it toyour word board. We hope you had as much fun as we did learning about Geometry!
16FLIP Watch the tree flip! Why is this a flip? original treeFLIPWatch the tree flip!Why is this a flip?The tree is flipped from top tobottom. Each new tree is the same sizeand shape as the original.Back toMain Menu
17All of the shapes that we used earlier for patterns have symmetry! Why do they have symmetry?These shapes are symmetrical because youcan draw a line that will split the shape intotwo parts that are exactly the same.Back toMain Menu
18similar to turns in math! More on TurnsThings that we turn aresimilar to turns in math!Back toMain Menu
21When we look at honeycomb close up we can see a natural tessellation!
22-There are so many things that are symmetrical about our bodies! Look at your neighbor. You may not know it,but their body has symmetry and so does yours.More on SymmetryMary and Melody have symmetry.We both have:2 eyes, 2 ears, 2 arms, 2 legs and 2 feet-There are so many things that are symmetrical about our bodies!Where is the imaginary line that divides your body into two parts?Back toMain MenuMaryMelody
23More on Tessellations On your worksheet you will see many objects. Put an X through the objects that you and yourpartner feel cannot be tessellated.brickcarpetsidewalkThese are pictures of tessellationsthat we found at our school. Youmight want to look for tessellationsin your classroom or at home.One last thingabout tessellations!
24Click here to see a tessellation More on TessellationsLook at some more shapesthat can be tessellated!Some of them have been tessellatedon the page. All of the shapes canbe tessellated because they fit togetherwithout any gaps!Click here to see a tessellationfound in nature!
25Tessellation Tessellation Has no gaps and it has no end. Tessellation! It is a fun word to say…Tessellation!Math and artcome together and play.What I seeis up to me!Tessellation!Help me think of thingsit can be.
26Why is this a Tessellation? This is a tessellation because thetriangle is repeated over and overfilling the space without any gaps.Many objects can be tessellated.All it takes is many of one objectthat fit together like a puzzle.A circle cannot be used for atessellation because when you fitthem together there are many gaps.

31TURNoriginal light bulbClick the mouse and watch the light bulb turn. You will have to click four times to see the light bulb turn all the way back to where it started.Why is this a turn?In this case the light bulb has stayed the same size and shape as the original bulb. However with every click the bulb changes direction .Back toMain Menu
