Hundreds Chart With Missing Numbers on US Letter, exactly as it prints.
A missing-number chart turns the hundreds chart from something to read into something to reason about. The number above a gap is ten less, the one below is ten more, and the ones either side are one less and one more — so every gap can be solved several ways, and checked against the others.
Forty percent of the squares are empty by default. Lower the share for a first attempt, raise it for a challenge, and change the worksheet version to shuffle the gaps so that neighbours in class get different sheets.
Every sheet here is free, adjustable and prints at exact scale.
At random, but the same way every time for a given worksheet version, so a sheet printed today can be printed again next week. Change the version for a new set of gaps.
Start around 20% for children new to the chart and work up to 60% or more. At 90% the sheet is close to a blank chart with a few clues.
Set Numbers shown to Every other. Half the squares go empty in a chequerboard pattern, so no row or column can simply be copied along.
Yes. Set Last number to 120 and the gaps are spread across all twelve rows.
