These sequences are missing numbers and require some skip counting to complete. Scholars finish rows of numbers first counting by 1s, then 10s, and finally 100s. Each has three given numbers to get them started, and they fill in five more. There is a guide to skip counting at the top, so consider reviewing it before they do this. What patterns do learners notice as they count by 10s and 100s? Get out a hundreds chart to really see what's going on.
