Presentation transcript:

Division of Large Whole Numbers Divisor – The number that divides into another number. Dividend – The number that is being divided. Quotient – The answer to a division problem Estimate the Quotient! Round the divisor and use mental math to estimate… Then calculate to check. Division of Large Whole Numbers 32,677 ÷28= ________________________ 45,360 ÷62= __________________________ Round 28 to 30… Ask “How many 30s go into 32,677?” 10, 100, or 1000 Round 62 to 60… Ask “How many 60s go into 45,360?” 70, 700, or 7000

Estimate the quotient. Then calculate to check. 76,864 ÷ 562 = ______________________ Discuss what you would round the divisor to. ____________ Discuss what the estimated quotient. ___________ Check with a calculator.
