A 1st grade math review in seven short parts: addition and subtraction facts within 20, missing-number problems like 7 + __ = 12, counting tens and ones with base-ten blocks, telling time to the hour and half hour, comparing two-digit numbers, and two word problems. Everything prints on about two pages, with an answer key after.

These match the main 1st grade standards: add and subtract within 20 (fluent within 10), understand the equal sign and missing addends, understand tens and ones, compare two-digit numbers, and tell time in hours and half-hours. Use it as a monthly check: a part that's hard tells you what to practice. Single-skill sheets: 1st grade addition, 1st grade subtraction, tens and ones, 1st grade telling time and 1st grade word problems.

Tips for using it

  • Missing addends (7 + __ = 12) are subtraction in disguise; count up from 7.
  • Do one page a day, not both at once.
  • Press New problems each week for a fresh review with the same skills.
