This is a 16 page smart board math lesson for first grade. I use this for my students morning work. I would do a page a day, the students would work the problems in their math journals and we would go over the answers before we started math for that day. I would call students to the board and have them work the problem out on the board and explain how they got their answer to the class. This lesson includes missing addends up to 20, greater than, less than, equal to, and place value up to the tens place.
