When asked to multiply numbers with zeros, students love it. They realize they may disregard the zero during calculations and only include it again when recording the result. There is a lot of practice with this concept in the multiply 3-digit multiples of 10 with 1-digit numbers worksheet. As the worksheet uses a horizontal format, it allows for more creativity when it comes to how the student solves the problem. In contrast, in the vertical format, students usually employ the standard method to solve.
