Take the three matzot - the broken piece between the two whole ones – and recite the following blessing:

בָּרוּךְ אַתָּה יי אֱלֹהֵינוּ מֶלֶךְ הָעוֹלָם הַמּוֹצִיא לֶחֶם מִן הָאָרֶץ.
 

Baruch atah Adonai, Eloheinu melech ha-olam, hamotzi lechem min ha-aretz.
Praised are you, Adonai, 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:

בָּרוּךְ אַתָּה יי אֱלֹהֵינוּ מֶלֶךְ הָעוֹלָם, אֲשֶׁר קִדְּשָנוּ בְּמִצְוֹתָיו וְצִוָּנוּ עַל אֲכִילַת מַצָּה.
 

Baruch atah Adonai, Eloheinu melech ha-olam, asher kid'shanu b'mitzvotav v'tzivanu al achilat matzah.
Praised are you, Adonai, 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
