Grade 1 Number Charts

A hundreds chart is one of the most useful tools in first grade, and these number charts for grade 1 give a child real practice reading and filling one. On the missing-number pages part of a 1-100 chart is blank, and the child writes the numbers that belong, using the pattern of the rows and columns to work out what goes where. Filling the gaps builds number sequence and place-value sense as a child sees how the tens line up down each column.

Because a hundreds chart is so orderly, a first grader can reason a missing number out -- the number just after, just before, or ten more down the column -- rather than guessing. That reasoning is exactly the number-sense work first grade aims for, and it makes later adding and skip-counting far easier. Some sheets fill short number lines to twenty first, then build up to the full hundreds chart for children ready to stretch.

More than a dozen first-grade number chart sets are ready to use. Print a worksheet as a PDF for a math station or homework, print the answer key so you can check every filled number quickly, or complete the same chart online with a tap. It is completely free for everyone, with no account, no sign-up, and no limit -- steady, structured practice with the order of numbers to a hundred.
