We talked about being married in the temple when we are grown up. The point was supposed to be that a man who holds the Priesthood performs the sealing ordinance, but the children were unanimous in declaring that they did not want to be married, because then they would have to kiss somebody, and kissing is gross! On the other hand, they all know that families are forever and are happy that their parents were married in the temple
We had a good time looking at pictures of the Houston Temple and several other ones, and talking about how they all looked different, but are all the House of the Lord.
We talked about father's blessings for when we need comfort or extra help with a difficult situation. At least one of the children remembered having this kind of blessing and how warm and safe she felt afterward.
We had a wonderful time coloring "I Love to See the Temple" flip books. All five children argued with their parents about leaving at the end of class, because they wanted to stay and finish their project!
