  1. Dividing by Powers of Ten

  2. Bell Ringer • Multiply using a pattern. • 1.8 x 101 • 0.347 x 103 • 5.45 x 103 • 0.639 x 104 • 67.835 x 102

  3. Objective • Use your understanding of multiplying by powers of ten to mentally divide by powers of ten.

  4. Anchor Task 27 ÷ 101= n 27 ÷ 102= n 27 ÷ 103= n

  5. Guided Practice • Solve the following. Record your quotients without the place value chart. • 58 ÷ 101 = n • 469 ÷ 102 = n • 92.6 ÷ 103 =n • 0.5 ÷ 101 = n • 7.68 ÷ 103 =n • 4.7 ÷ 102 = n
