Write an equation to show the multiplication problem this model represents.
3 xx 2/3 = 6/3 or 2
100
Write the equation that is represented by this model.
2/3 xx 3/4 = 6/12 or 1/2

What is a reasonable estimate for 5 1/3 xx 3?
Will the actual product be a little bit MORE or a little bit LESS than your estimate?
15 is a good estimate beause 5 x 3 = 15
The actual product will be a little bit more than 15, because 5 1/3 is a little bit more than the 5 used in the estimate.

The product of two of the fractions listed below is 3/8 . Which 2 fractions can be multiplied together to get that answer?
1/2 1/3 2/3 1/4 3/4
1/2 xx 3/4 = 3/8
400
Estimate, then use an area model to multiply 3 1/2 xx 2 2/3
A reasonable estimate should be between 9 and 12. (3 x 3 = 9 and 4 x 3 = 12)
3 1/2 xx 2 2/3 = 9 2/6 or 9 1/3

The product of two of the fractions listed below is 1/6. Which 2 fractions can be multiplied together to get that answer?
1/3 2/3 1/4 3/4
This one is tricky! Did you think about equivalent fractions?
500
Estimate, then use an area model to multiply 2 3/4 xx 4 2/3
A reasonable estimate should be around or a bit smaller than 15. (3 x 5 = 15, and both of the factors were rounded up, so the product would be less than 15)
2 3/4 xx 4 2/3 = 12 10/12 or 12 5/6
