Multiplying Larger Numbers

We have been learning how to multiply large numbers in class. Our practice of small multiplication facts has helped us with our computation skills in this unit. This month, we learnt a few strategies for multiplying larger numbers, such as estimating to find an answer, multiplying numbers with zeroes (40x2), using expanded form to multiply, and multiplying from right to left (or as we've started calling it in class: "old school"). The students have practiced these skills using arrays and base ten blocks. There are pictures under March of us practicing multiplying using manipulatives.
