SYMMETRY

Symmetry is an exact mathematical "patterned self-similarity" that can be demonstrated with the rules of a formal system. Although these two meanings of "symmetry" can sometimes be told apart, they are related, so they are here discussed together.
Mathematical symmetry may be observed

• with respect to the passage of time;
• as a spatial relationship;
• through geometric transformation, such as reflection and rotation ;
• through other kinds of functional transformations;
 

 

The opposite of symmetry is asymmetry (No Symmetry)

This is also the example of Grade 5 assignment...

LEARNING ACTIVITY "Math English_Shape"

Fun activity for brainstorming, the lesson of this class was "SHAPE". Before they do this activity, firstly they watched some video about shape. Then we're recalling first what shape they saw just now. Repeat...repeat...repeat...and repeat, after this they did to make some shape from plasticine.

My students' activity "Math English_Money"

Students play "money in coin and piece" by using timing slide in group. They finish this by analyzing word solve problem question. They're so excited. Because they work with time, so all the children will work and focus on the job.
