Mental Math Worksheets for Grade 4 — Numbers to 1,000
In Grade 4 mental math changes scale: numbers go up to 1,000, multiples of 25 become a handy tool and children multiply by 10 and 100. The generator offers the four operations: addition and subtraction of three-digit numbers (or multiples of 25), multiplication (numbers from 11 to 25 by 2 to 6, numbers by 10 or 100, tens by a single digit) and exact division (by 2 to 9, or a multiple of 10 by 10). The generator avoids repeating the same calculation on a sheet.

Numbers to 1,000
Addition and subtraction with three-digit numbers, and with multiples of 25 (175 + 50), a classic mental-math anchor.
×10, ×100 and ×2 to ×6
Multiply by 10 and 100, double numbers from 11 to 25, multiply tens: three different moves.
Exact division
The quotient is always a whole number: 144 ÷ 6, 480 ÷ 10. No remainder, so the focus stays on the times tables.

Frequently asked questions
Which operations are on a Grade 4 sheet?
All four: addition, subtraction, multiplication and division. You can tick just one or two to target a difficulty.
Do the divisions have a remainder?
No: Grade 4 divisions are exact. They rely on the times tables or on dividing a multiple of 10 by 10.
Do decimals appear in Grade 4?
No, the Grade 4 sheets only use whole numbers. Tenths and hundredths come in the Grade 5 sheet.
Are the answers on the sheet?
No, the student sheet does not show the answers. You can check with a calculator or redo the calculations together.
