Oct. 8, 2015 An algorithm is a procedure for solving a problem. Pass in your H.W. (in class’s tray don’t forget your name!) Pick up a NEW packet (on top of projector). On front cover of packet, fill in NAME, CLASS and DATE. Copy the two items below onto the cover of your NEW packet (anywhere is fine) An algorithm is a procedure for solving a problem.
Today’s Objective: Oct. 8, 2015 I will estimate, make a table of values, and use place value to divide multi-digit numbers using the division algorithm. I will demonstrate my understanding when I can independently complete all of pg. 58 using the division algorithm. (6.NS.B.2)

ESTIMATING : pg. 55 Oct. 8, 2015 70,000 ÷ ? ………….….70,072…………….? 80,000 70,000
ESTIMATING : pg. 55 Oct. 8, 2015 70,000 ÷ 20 ? ………….….19…………….? 20 10
ESTIMATING : pg. 55 Oct. 8, 2015 70,000 ÷ 20 Divide each number by ten for efficiency. The quotient of 70,072 and19 should be about 3,500.
ESTIMATING : pg. 55 Oct. 8, 2015 Because the divisor,19 ,is not a friendly number , a good strategy is to create a table of values to show the multiples of 19.

ESTIMATING : pg. 56 Oct. 8, 2015 The quotient of 14,175 and315 should be about 50.
Center Work: Oct. 8, 2015 Students are to: Pick up a “Table of Values” worksheet and complete. When done, move to Center 2 or Center B and go to pg. 58 of packet. Complete the ESTIMATING part only of pg. 58. When done, move to Center 3 or Center C and divide the problems on pg. 58 using the algorithm. Center 1 Algorithms Center A Algorithms Center B Estimating Center 2 Estimating Center 3 Table of Values Center C Table of Values

Explain in your own words how the division algorithm works. Closing: Oct. 8, 2015 Explain in your own words how the division algorithm works. The division algorithm shows successive (one after the other) estimates of the quotient organized by place value, …..other answers…… the division algorithm breaks one large division problem into several smaller ones organized by place value.
