Today we learned a very sophisticated word for what we found to be a simple concept! The word is symmetry. In grade three symmetry is when you cut a shape in half and both sides are the exact same shape and size (we call this congruent). The line that divides the shape into equal parts is called "the line of symmetry." Some shapes have more lines of symmetry than others (example: a square has 4 while a rectangle has only 2).
Boys and girls, today in class we printed our first names in all capital letters and found which letters were symmetrical. Tonight, try writing your last name in all capitals and do the same activity!
