  1. Division Patterns and Estimating Quotients

  2. Division Math Vocabulary • Compatible Numbers • Numbers in a problem that are easy to work with mentally. • Division • An operation that is the opposite of multiplication. It breaks a number up into even groups. • Dividend • A number that is being divided • Divisor • The number by which the dividend is being divided • Quotient • The answer or result of a division problem

  3. Dividing Mentally! 600 ÷ 6 = 100

  4. Dividing Mentally! 270 ÷ 90 = 3

  5. Dividing Mentally! 25,000 ÷ 500 = 50

  6. Draw a Picture to Solve 92 ÷ 4 =

  7. Draw a Picture to Solve 78 ÷ 6 =

  8. We can Estimate in Division Too!!!

  9. Find a Compatible Dividend Estimate 156 ÷ 3 • ÷ 3 150 ÷ 3 = 50 We change 156 to 150 because 150 and 3 are compatible numbers

  10. Find a Compatible Divisor Estimate 3,200 ÷ 90 3,200 ÷ 90 3,200 ÷ 80 = 40 We change 90 to 80 because 32 and 8 are compatible numbers.

  11. Bring to the Nearest Ten Estimate 228 ÷ 43 228 ÷ 43 228 ÷ 40 240÷ 40 = 6 We change the divisor to the nearest 10. We change the dividend to a number that is compatible with 4. Look, It’s easy to divide 24 by 4.
