Ví is trying to figure out how a square can be divided into four equal parts. Show her at least three different ways to divide a square into four equal parts.
Can you think of different ways to draw a line that divides the square into two equal parts first? Try it!
Try drawing a straight line from one corner of the square to the opposite corner. How many equal parts are there? Now draw another line connecting the other two corners. Can you think of another way?
