توضیحات
If your first grader is looking for a number challenge, we've got the worksheet for her. She may be a whiz at adding two numbers together, but can she add three numbers? Adding three numbers horizontally is a great way to practice mental math and addition facts. The problems start out easy, but get progressively harder; if she starts to struggle, just remind her to take each problem two numbers at a time.
