Main Idea
Example 1: Problem-Solving Strategy
• I will solve problems by looking for a pattern.
Shawna is training to run in a half-marathon. A
half-marathon is about 13 miles. On her first day
of training, she ran 1.25 miles. Then she
increased her distance each day according to a
pattern. Here are the numbers of miles Shawna
ran the first five days of training.
1.25, 1.85, 2.45, 3.05, 3.65
Based on her pattern, how many miles will
Shawna run on her sixth day?
Understand
What facts do you know?
• We know how many miles Shawna ran each
day for five days.
• She increased the distance she ran each day
according to a pattern.
What do you need to find?
• The number of miles Shawna will run on the
sixth day.
Plan
One way to solve the problem is by looking for a
pattern among the number of miles she ran each
day for five days. Then extend the pattern to find
the number of miles she will run on the sixth day.
Solve
Use your plan to solve the problem.
Find the amounts by which Shawna increased her
distances.
1.25
1.85
2.45
3.05
3.65
Solve
Shawna increases her distance by 0.6 mile each
day. Add 0.6 to 3.65 to find the number of miles
Shawna will run on the sixth day.
3.65 + 0.6 = 4.25
Answer: So, on the sixth day, she will run 4.25 miles.
Check
Look back at the problem by subtracting.
4.25 – 0.6 = 3.65. So, the answer is correct. 
