This 1 more,1 less, 10 more, 10 less math worksheet would be great for introducing the topic of finding 1 less, 1 more than a number and 10 less, 10 more than a number. It is set up in a grid formation to help students relate to the hundreds chart. It could even be used for a pretest to the lesson to see what the students understood before beginning the lesson.
