Create a missing-number chart for counting practice. Choose a 1–100 or 1–120 chart, then select how many cells should be left blank.
Preview the chart and its matching answer key before printing or downloading a PDF. A new set hides a different selection of cells while preserving the chart’s counting order.
Fill in the missing numbers.

Here, the question count is the number of missing cells on one chart. Start with six blanks to leave plenty of nearby clues, then try twelve or eighteen. The key fills those same cells; it is not a different chart.
In a ten-column chart, the cell after 25 is 26 and the cell below 26 is 36. Use both directions to check a missing value.
