What 1st graders learn in math

First graders are expected to add and subtract within 20, understand that a two-digit number is tens and ones, compare two-digit numbers, tell time to the half hour, and measure with non-standard units.

The sheets on each page run from easiest to hardest, so start at the left and move on when a sheet is easy.
