Addition and Subtraction without Regrouping

1. 1. The James family went on a road trip. During the first week, they drove 342 miles. The second week they drove 201 miles. The third week they drove the same distance as week two. How long was their trip?

• a. 342 - 201 = 142 miles

• b. 342 + 201 + 201 = 744 miles

• c. 342 + 342 + 201 = 884 miles

2. 2. Jack, Ted and Sandy were pressure washing the sidewalks. Jack cleaned up 427 meters, while Ted cleaned up only 300 meters. If the space covered by Sandy measures the same as Ted, how much of the side walk was cleaded?

• a. 427 + 300 + 300 = 1 027 meters

• b. 427 + 300 = 727 meters

• c. 427 + 300 + 300 + 927

3. 3. The triplet had a doctor's visit. One baby weighed 21kg. If all the babies each had the same weight, how much did they weigh altogether?

• a. 3 + 3 + 3 = 9 kg

  or

  3 x 3 = 9 kg

• b. 21 + 3 = 24 kg

• c. 21 + 21 + 21 = 63 kg

  or

  21 x 3 = 63 kg

2. 2. A brand new Samsung cell costs $1,231. A iPhone costs $1 648. How much more does the iPhone cost?

• a. $1 231 + $1 648 = $2 879

• b. $1648 + $231 = $1 879

• c. $1 648 - $1 231 = $417

5. 5. The warmest day of this year was 115°C (degrees celsius). The coldest day of the year was 12°C (degrees celsus). What is the difference between the warmest and coldest days of the year? 

• a. 115°C - 12°C = 103°C

• b. 115°C + 12°C = 128°C

• c. 115°C - 12°C = 113°C
