CCSS.Math.Content.5.NBT.B.5 Fluently multiply multi-digit whole numbers using the standard algorithm.
In fifth grade, students learn to use and apply the standard or traditional algorithm for multiplication. To learn this students move from place value to multiplication by powers of ten and decimal fractions to review of the area model and partial product then learning and practice of the standard algorithm. These Learn Zillion lessons are helpful when teaching this unit. Note that Learn Zillion is a free resource, but teachers and families need to make an account to use it.
