Here's a fun review or extra credit activity for Bridge to Terabithia by Katherine Paterson. There are 16 clues with corresponding lettered answers. Put the number of the corresponding clue in the square for the letter of the answer, and when all answers are correct, the columns and rows will each add up to the same number.
Fun review! Excellent, educational filler for students who finish reading or other assignments early. Includes answer key.
