Answer 1

Which strategy would not correctly solve this story problem?

It took Dennis twice as long to walk to the park as it did to walk to the store. He walked to the store in 15 minutes. He spent 5 more minutes walking to the library than to the store. How much time did Dennis spend walking?

A.
Work backward. Start with 5 minutes and add it to 15. Then add 15 more minutes to the sum to find the total time Dennis walked.

B.
Use logical reasoning. Dennis walked for 2 periods of 15 minutes, another period of 15 minutes, and 1 more period of 15 minutes plus 5 more minutes. So Dennis walked for 4 × 15 minutes plus 5 more minutes.

C.
Translate into an equation. 2 × 15 + 15 + 5 + 15 = m

D.
Draw a diagram. Draw 2 lines and write 15 min above each line. Draw another line and write 15 min above it. Draw another line and write 15 + 5 above it. Add up all the amounts above the lines to find the total time Dennis walked.

Answer 6

Which strategies can be used to solve this problem?

The car assembly line workers at a new factory painted 5,000 cars in its first year, 7,213 cars in its second year, and 8,201 cars during its third year. How many more cars did the workers paint in its first and second years together than in its third year?

Choose all answers that are correct.

A.
Draw a diagram. Draw three circles. In one write 5,000, in another write 7,213, and in the third write 8,201. Draw an x through the circle with 8,201 written in it. Circle the other two circles with a larger circle.

B.
Translate into an equation.
(5,000 + 7,213) – 8,201 = c

C.
Work backward. Add 5,000 (cars painted first year) to 7,213 (cars painted in second year). Add 8,201 (cars painted in third year).

D.
Use logical reasoning. Combine the totals for cars painted in the first two years (5,000 + 7,213). Subtract 8,201 (cars painted in the third year) from the sum to get the answer.
