The pool at the park is about 96 feet long.
If Randy swims across the length of the pool 2 times, about how many feet will he swim?
Before choosing an answer, explain how you would figure out the total distance Randy swims. Type your answer.
Choose your answer: Next check the Explanation and AI Feedback

96 feet

100 feet

150 feet

192 feet

Explanation:
Randy swims the full length of the pool twice.

So add:
96 + 96 = 192
1 carry 1 to tens
96
+ 96
-------
192 correct answer

or multiply:
96 x 2 = 192 At grade 3 you are expected to memorize your 10 x 10 multiplication table.

Randy swims 192 feet in total.

Your reasoning vs. correct reasoning:
(AI compares the student's written explanation to the correct multiplication or repeated - ddition steps.)

AI Feedback + Sam Ortega (human expert checking) making sure no hallucination

1 carry 1 to tens
96
+ 96
-------
192 correct answer

If student chose 96: wrong answer
That is only one trip across the pool. Randy swims twice.

If student chose 100: wrong answer
This looks like rounding 96 to 100, but the problem asks for the exact distance.

If student chose 150: wrong answer
This is too small. You may have added incorrectly or estimated instead of doubling.

If student chose 192: correct answer
Great job! 96 x 2 = 192.
You correctly used repeated addition or multiplication to find the total distance.

SKETCH TO VISUALIZE THE PROBLEM

Randy swims across a 96 - foot pool 2 times.

Total distance: 96 ft + 96 ft = 192 feet.
or 96 ft x 2 = 192 feet.

Reflection:
Was this problem easy, medium, or hard for you?
Did multiplying by 2 feel easier than adding 96 twice? Type your answer.
