Martin Luther King, Jr.
MLK Day is celebrated each year on the third Monday in January. Most school systems are off that day, but it's still fun to do activities related to the holiday, whether it is the Friday before MLK Day or the Tuesday after.
In my Teachers Pay Teachers store I have an ABC order activity. It comes with 16 Martin Luther King, Jr. themed vocabulary cards, which are to be cut out and put in a baggie. Students will lay the cards out in the correct order and then once they have them set up, they will copy the words onto the MLK themed skill sheet. The skill sheet is suitable for taking a grade. There is also writing paper to go along with the MLK theme where students will write a letter to Martin Luther King, Jr. telling him what they would say to him if he were alive today. This makes for a great literacy center activity.
