My sweet and sassy 1st-grade team wanted an independent practice activity for skip counting by 10s off the decade. They wanted it to look like the hundred chart, so the kiddos could make the connection to the patterns in the hundred chart. They also wanted it to be differentiated, so they could meet the kiddos at their level. I came up with the ladder activity shown below. Notice that the three versions use the same numbers, but they are increasingly difficult because of the number hint that is shown. I also added a completely blank one you can customize.
