Input-output tables for fourth grade use one-step rules (add 7, subtract 4, multiply by 3) with a couple of Out values missing from each table. Your child applies the stated rule down the column, a first taste of how functions behave.

The kind of problems you'll get

Read the rule directions. Complete each table or written response.

  1. The rule is “multiply by 3, then add 1.” The input is 4.

    Answer: 4 × 3 + 1 = 13, so the output is 13.

Most problems on this sheet sit beside a picture, model or diagram, so this is the worked example the sheet itself prints. The answer key on page two prints the answer under every problem.

Every print pulls a fresh set of problems at this level, so a make-up test or a second sibling never gets the same sheet.

What's on a 4th grade sheet

Every version prints on US Letter or A4, with its answer key after the problems.

How to teach this

Say the rule out loud for the first row together ("add 7, so 2 becomes 9"), then let your child run the rest alone. Keep a finger on the In number while writing the Out, since most slips come from reading the wrong row. Check one finished row by undoing the rule.

Watch for: Kids write a rule that fits only the first row. 1 to 5 could be add 4 or times 5, so test the rule on every row before committing. Kids change rules partway down, adding on one row and multiplying on the next. One table follows one rule, top to bottom.

Common questions about 4th grade input-output tables

What do the rules look like in 4th grade?
One step only: add 7, subtract 4, multiply by 3. The rule is printed above each table, and your child fills in the missing Out values.
How does my child write the answers?
As the missing numbers in order, like 12, 15. The answer key lists the same values, so checking takes a glance.
