  1. The Brandywine School District presents The Singapore Math Series Session III Multiplication and Division Created by Hester Sutton March 2011

  2. Problem Solving Words diagram Arithmetic

  3. Part-Whole Model (Multiplication and Division) whole part one part x number of parts = whole whole ÷ number of parts = one part whole ÷ one part = number of parts

  4. 5 children shared the cost of a present equally. Each of them paid $6. What was the cost of the present? ? Cost of the present $6 x 5 = $30 $6 whole one part number of parts

  5. Part-Whole Model (Multiplication and Division) whole part one part x number of parts = whole whole ÷ number of parts = one part whole ÷ one part = number of parts

  6. Four children bought a present for $28. They shared the costs equally. How much did each child pay? 28 Cost of the present $28 ÷ 4 = $7 ? whole one part number of parts Each child paid $7

  7. Part-Whole Model (Multiplication and Division) whole part one part x number of parts = whole whole ÷ number of parts = one part whole ÷ one part = number of parts

  8. A group of children bought a present for $30. They paid $6 each. How many children were in the group? $30 Cost of the present $6 30 ÷ 6 = 5 number of parts whole one part

  9. Multiplication with Rebundling 43 x 4 = 172 hundreds tens ones

  10. There were 27 desks to clean. 3 boys shared the work equally. How many desks did each boy clean? 27 3 units = 27 Desks 1 units = 9 ? Each boy cleaned 9 desks.

  11. = 7 hundreds tens ones

  12. Comparison Model (Multiplication and Division) larger quantity smaller quantity smaller quantity x multiple = larger quantity larger quantity ÷ multiple = smaller quantity larger quantity ÷ smaller quantity = multiple

  13. A farmer has 7 ducks. He has 5 times as many chickens as ducks. How many chickens does the farmer have? ? chickens 1 unit = 7 ducks 5 x 7 = 35 5 units = 35 7 The farmer has 35 chickens

  14. Comparison Model (Multiplication and Division) larger quantity smaller quantity smaller quantity x multiple = larger quantity larger quantity ÷ multiple = smaller quantity larger quantity ÷ smaller quantity = multiple

  15. A farmer has 35 chickens. He has 5 times as many chickens as ducks. How many ducks does the farmer have? 35 chickens 5 units = 35 ducks 35 ÷ 5 = 7 1 unit = 7 ? The farmer has 7 ducks

  16. Comparison Model (Multiplication and Division) larger quantity smaller quantity smaller quantity x multiple = larger quantity larger quantity ÷ multiple = smaller quantity larger quantity ÷ smaller quantity = multiple

  17. A farmer has 7 ducks and 35 chickens. How many times as many chickens as ducks does the farmer have? 35 chickens ducks 35 ÷ 7 = 5 7 The farmer has 5 times as many chickens as ducks

  18. Kelly has $16. She has twice as much as her brother. How much money do Kelly and her brother have together? 16 2 units = $16 Kelly 1 units = $8 ? 3 units = 8 x 3 = $24 Brother 8 They have $24 altogether.
