Show a six-year-old 5, 5 and 10 and ask what goes between the fives, and most will say plus without a second thought. Show 10, 5 and 5, and the same child may hesitate. This 1st grade plus or minus sign worksheet is built on that moment. Each of the eight colored boxes holds a number sentence with a small circle and a question mark where the sign should be, such as 17, 3 and 14 or 8, 5 and 13. Under each sentence, two circles show a plus and a minus. Your child colors the one that makes the sentence true. In the first box, the minus is already colored as an example. A second page gives the answer key.
