Ascending Order Worksheet to 20 for First Grade

About this worksheet

Eight sets of four numbers run down the page, each with four empty boxes beside it. A child reads the set, finds the smallest, and writes the four numbers across in order.

Nothing decorates this one, which is the point of having it in the set. Every number falls between 1 and 20 and no number repeats inside a set, so a child who can count that far has everything they need. Sets like 8, 20, 12, 2 deliberately open with a middle number so nobody can copy the first number down and hope, and the spread of each set is wide enough that the comparisons stay easy to see.

What students will practice

• Compare numbers within 20
• Arrange four numbers from smallest to largest
• Write numbers into ordered boxes
