Subtract to find the difference. Hint: think about 10s and ones. Use base 10 blocks to help you. Six subtract four equals what. 60 subtract 40 equals what.

In this question, we’re told to think about 10s and ones and use base 10 blocks to help us subtract four from six and 40 from 60. If we have six base 10 blocks and then we subtract four 10s, how many 10s do we have left? There are two. We know that six subtract four is two. Six 10s subtract four 10s equals two 10s. 60 subtract 40 equals 20. Six 10s are 60. If we subtract four 10s or 40, we have two 10s left. And two 10s are 20.
