Mental Division Strategies

Check every quotient by multiplying: if 56 divided by 7 is 8, then 8 times 7 should be 56. For dividing by 10 and 100, ask how many tens or hundreds are in the number. Use the color by number page for relaxed fact practice.

Divide in your head by breaking the dividend into two easy parts. Mental math means solving in your head. The dividend is split into two friendly parts. Divide each part, then add the quotients. Problems on the page include 92 ÷ 4, 64 ÷ 8 and 112 ÷ 7. The directions on the page read: Read the example. Then, divide each part and add the two quotients in the boxes. The page opens with a worked example, and the answer key shows every answer.

Yes, both. We made it for 4th Grade mental division, and the page works the same whether it lands on a kitchen table or a center rotation. At home, most families go through it together and talk the answers out loud, and that talking is where most of the learning happens with division facts and mental strategies. In class it runs well as independent work while you pull a small group. Print one copy or thirty, whichever the day needs.

Think in tens and hundreds. The number 270 is 27 tens, so 270 ÷ 10 = 27, and 5,300 is 53 hundreds, so 5,300 ÷ 100 = 53.

To find 56 ÷ 7, ask what number times 7 makes 56. Since 7 × 8 = 56, the quotient is 8. Division facts to 12 are the inverse of the multiplication table, so strong multiplication facts make division quick.

Break the dividend into two easy parts. For 84 ÷ 4, split 84 into 80 and 4, divide each part by 4 to get 20 and 1, then add to get 21.

The mental division sheet supports 4.NBT.B.6, which covers dividing with strategies based on place value, properties and the relationship to multiplication.

5 printable worksheets, all free to preview. Downloads are included with a ClassWeekly free trial, and every page prints on standard 8.5 x 11 paper.

These are written for 4th Grade students, roughly ages 9-10. Many teachers also use them a grade up for review or a grade down as an extension, so use the preview to judge the fit for a particular child.

Yes. Each one shows the Common Core code it covers on its own page, so you can check the alignment yourself rather than taking our word for it.
