Have letters that spell 'Thanksgiving' and put them around the room. On the back of each letter, write a song. Let a child choose a letter and put it on the board. Then sing the song. Have the children see if they can put the word together!!!
-Side note- my children are incredibly smart.. even my Junior Primary. I swear sometimes they are smarter than me..... seriously. I did this same idea for Easter and they knew what the word was on the second letter! So if you wanted to make this harder, spell the word Gracias, Merci, or Blessings. Good luck!
