Lesson 1.6 – Problem Solving

2. Copy everything below
Objective - To identify relevant information to solve a problem and to find missing terms in a sequence.
The Problem Solving Plan
Understand the Problem
Write the question from the problem
Write the item you are finding
Cross out or identify irrelevant info (or extra info)
Make a Plan
Write out the facts and math operation you will use
Solve the Problem
Do all of the math
Look Back
See if your answer is possible or reasonable
Make sure you use labels

3. 1) Joe has $17.50. If he buys 3 pens for 70 cents
WRITE DOWN THIS PROBLEM SOLVING
1) Joe has $ If he buys 3 pens for 70 cents
each and a ruler for $1.20, how much will he spend?
Write out: “Question is how much will he spend?”
Finding? I am finding an amount of money
Cross out (or write): “Irrelevant: Joe has $17.50.”
Understand The Problem
Make a Plan
Let me find out how much Joe will spend for 3 pens by multiplying, then add it to the cost of the ruler.
Solve the Problem
Multiply: 3 • 0.70 = 2.10
Add: = 3.30
Look Back
Label: $3.30
Does it make sense???

4. 2) The local theater seats 1200 people. If 570 adult
tickets are sold for $3 each, and 200 child tickets
are sold for $1.50 each, how much was raised?
Try
This
One
Understand The Problem
Write out: “Question is how much was raised?”
Finding? I am finding an amount of money
Cross out (or write): “Irrelevant: The local theater seats 1200 people.”
Make a Plan
Let me find the total raised from adult tickets, then the total raised from child tickets. Then add both totals.
Solve the Problem
Multiply: 570 • 3 = and 200 • 1.50 = 300
Add: = 2010
Look Back
Label: $2,010
Does it make sense???

5. A sequence is an order list of numbers that has a constant pattern
Sequences
A sequence is an order list of numbers that has a constant pattern
1, 3, 5, 7, __, __, __ 9 11 13
3, 6, 12, 24, __, __, __ 48 96
192 +2
The pattern is each number increases by 2.
The pattern is each number multiplies by 2.
25, 21, 17, 13, __, __, __ 9 5 1
800,400,200,100, __, __, __ 50 25
12.5
Copy everything above -4
The pattern is each number decreases by 4.
The pattern is each number divides by 2.

6. Find the next three terms of each sequence below
and describe the pattern.
1) 1, 3, 9, 27, ___, ___, ___ 81
243
729
The pattern is each number is multiplied by 3
The pattern is each number subtracts 9, then adds 1
2) 81, 72, 73, 64, ___, ___, ___ 65 56 57 -9 +1 -9 +1 -9 +0
The pattern is the denominator increases by 1 3)
, , +1
