(4) And there shall be no leaven seen with thee in all they borders seven days; neither shall any of the flesh, which thou sacrificest the first day at even, remain all night until the morning. (5) Thou mayest not sacrifice the passover-offering within any of thy gates, which the LORD thy God giveth thee; (6) but at the place which the LORD thy God shall choose to cause His name to dwell in, there thou shalt sacrifice the passover-offering at even, at the going down of the sun, at the season that thou camest forth out of Egypt. (7) And thou shalt roast and eat it in the place which the LORD thy God shall choose; and thou shalt turn in the morning, and go unto thy tents. (8) Six days thou shalt eat unleavened bread; and on the seventh day shall be a solemn assembly to the LORD thy God; thou shalt do no work therein.
בָּרוּךְ אַתָּה יי אֱלֹהֵינוּ מֶלֶךְ הָעוֹלָם הַמּוֹצִיא לֶחֶם מִן הָאָרֶץ.
בָּרוּךְ אַתָּה יי אֱלֹהֵינוּ מֶלֶךְ הָעוֹלָם, אֲשֶׁר קִדְּשָנוּ בְּמִצְוֹתָיו וְצִוָּנוּ עַל אֲכִילַת מַצָּה.
Motzi-Matzah, Haggadot.com
Take the three matzot - the broken piece between the two whole ones – and hold them in your hand and recite the following blessing:
Praised are you, Lord our God, Ruler of the universe, who provides sustenance from the earth.
Before eating the matzah, put the bottom matzah back in its place and continue, reciting the following blessing while holding only the top and middle piece of matzah.
Praised are you, Lord our God, Ruler of the universe, who has taught us the way of holiness through commandments, commanding us to eat matzah.
Break the top and middle matzot into pieces and distribute them everyone at the table to eat a while reclining to the left.

Rabbi Rachel Barenblat, Velveteen Rabbi
Why do we eat matzah? Because during the Exodus, our ancestors had no time to wait for dough to rise. So they improvised flat cakes without yeast, which could be baked and consumed in haste. The matzah reminds us that when the chance for liberation comes, we must seize it even if we do not feel ready—indeed, if we wait until we feel fully ready, we may never act at all.
D'var acher / another interpretation: To Jewish mystics, matzah represents our most inner and hidden self. On Seder night, we renew our most essential self and rededicate it to living life with an awareness of God all around us. During Pesach we do not eat leavened bread because it represents the "puffiness" of arrogance and pride. (Adapted from Rabbi Jeffrey Goldwasser)
