Week 5
Focus SkillThis week’s focus skill is solving
real-world problems by finding patterns, illustrating the problem,
and checking for reasonableness
Finding Patterns
To solve some math problems, look for a pattern:
What would come next?

Finding PatternsJohn had a lot of pages of homework to do this week. He decided he would do one page on Monday, two pages on Tuesday, etc. so that it would be done on Friday. How many pages of homework did he have?
Finding PatternsJill wanted to get into better shape. She did 2 pull-ups on Monday, twice as many on Tuesday, twice as many again on Wednesday, and so on. How many pull-ups did she do on Friday?
Illustrate the Problem
To help us solve problems in math, sometimes we should draw a picture to illustrate what is happening.Mr. Palmer’s class has 36 students. If 7 students are sick one day, how many are in class that day?
Illustrate the Problem
To help us solve problems in math, sometimes we should draw a picture to illustrate what is happening.Bob has three bags of marbles. In each bag, there are six marbles. How many does he have altogether?
Illustrate the Problem
You Try One:
Theresa collects baseball cards. She got 12 for her birthday, 18 for Christmas, and 7 more when she got good grades. How many does she have now?
Illustrate the Problem
You Try One:
The jeans I wore yesterday had 4 pockets. In each pocket, I had 5 coins. How many coins did I have total?
