Here is an activity for any grade level that has spelling tests. It is called Spelling Detectives.
1.) Write the weekly spelling words in random order on the chalk board and tell the class to study the words carefully for one minute.
2.) Tell the students to put their heads down - no looking!
3.) Erase one of the words and rewrite it - this time spell it wrong.
4.) As the class has their heads down say, "Oh my, something looks wrong - all spelling detectives raise your heads and see if you can tell me what word is not spelled correctly."
5.) After 30 seconds, call on a volunteer to tell you the word and how it should be spelled. If the child answers correctly reward the class a point. If the child does not answer correctly, identify the word and give yourself 1 point.
6.) Repeat Steps.
