Click on interactive 100 number charts, then choose the 1-100 chart.  Scroll down and wait for the chart to load.  You can choose a color from the top and practice skip counting by 2's, 5's, and 10's.  Just click on the numbers to highlight them. (2, 4, 6, 8 or 5, 10, 15, 20 or 10, 20, 30, 40, etc)  You can also practice choosing numbers that come before, after, and between; numbers that are one more/one less; ten more/ten less; estimating to the nearest ten; etc.
