What's on this chart
The power of a hundreds chart is its shape. Because each row holds exactly ten numbers, moving one square down adds ten and moving one square up subtracts ten. A child who discovers that has learned something that survives long past this chart: adding ten does not change the ones digit at all.
Why this chart helps
The tens column is shaded so the end of each row is easy to find, and the fives are marked lightly, which turns skip counting into something you can see rather than recite. Count by twos and the even numbers make stripes; count by fives and the pattern narrows to two columns; count by tens and it collapses into one.
