3. Problem Solving Strategy “U-P-S”
Understand: Read the problem and think about the question. Each word is important. Missing a word or reading it incorrectly could cause you to get the wrong answer.
Plan: Think about how you can solve the problem. Look for key words and numbers. What do you need to do first? What do you need to do next?
Solve: Follow your plan, working logically and carefully. Make sure you solved all steps needed to answer the problem. Be sure you answered the question asked.

Long Beach Unified School District has , 572 students enrolled. Round this to the nearest __________.
 Underline the word that comes after “nearest”.
 Underline the digit in the indicated place.
 Circle the digit to the right of the underlined place.
 If the circled digit is 5 or greater, add one to the underlined place and change all digits to the right to zeros. 5 or
 If the circled digit is 4 or less, keep the underlined place and change all digits to the right to zeros.

6. Let’s Round Numbers!
Example: What is 45,638 rounded to the nearest thousand?
4 or less, stays the same
5 or higher, add one more
45,500
45,000
46,000
45,638
On the number line, 45,638 is between 45,000 and 46,000 but is closer to 46,000.

8. Why the Zero Place Holder?
PROBLEM: 23 X 45
 MULTIPLY by the ones digit “5”
 MULTIPLY by the tens digit “4”  
 The 4 represents 40. When you multiply by a multiple of 10 you have a zero in the ones place.

9. Let’s Solve Division Problems with Remainders
When you solve a division problem, sometimes you need to decide how to interpret the remainder.
Sometimes you use the REMAINDER to decide on the answer.
Example: The craft club members made 19 puppets. They want to package the puppets 5 to a box. How many boxes will they need? 3 R4
There will be 3 full boxes. Another box is needed for the 4 extra puppets. So 4 boxes are needed in all.

12. Naming Angles Obtuse Angle greater than 90° Acute Angle less than 90°
Right Angle
measures 90°
Hint: Have students use the corner of their scratch paper.
If the corner matches or lines up with the angle it is “right”!
If the corner leaves part of the angle showing, it is “obtuse” open.
If the angle doesn’t show when the corner is set on the vertex, the angle is “acute”. It is tiny or “cute”.
