Put it together: Multiplication of fractions assignment:
1. Write a multiplication word problem for 3/4 × 1/2 using a pound -
box - number of boxes model.
2. Draw a diagram for your word problem (label!)
3. Explain why the answer of the problem is 3/4 × 1/2 using length x
width = area explanation
4. Explain why the answer is multiplication using an amount in 1 set,
number of sets explanation.
5-8 Repeat all of the steps 1-4 for the numbers (2 1/2) × (1 1/3)
9. Explain how you can use the diagram in #6 to show each of these
computation steps:
a. (2 1/2) × (1 1/3) = (5/2) × (4/3)
b. (5 × 4)/(2 × 3)
10. Redraw your diagram from #6 and add to it to show why:
(20)/(6) = (20 ÷ 2)/(20 ÷ 2)
reminder: simplifying fractions uses a measurement division type of division
