Crack the Code

Guess the pictures, then add or subtract letters to form words on the blank spaces that are ‘simple machines’. Each blank space is for one letter. If you have it right, the word should fit perfectly on the blank spaces. Write your answers on a piece of paper, and keep the answer key covered at the bottom until you’re ready to check. Good-luck!
