This document discusses outcomes and how they can be used to measure the impact of library programs and services, especially teen services. It defines outcomes as benefits or changes in skill, knowledge, attitude, behavior, or life status, rather than just outputs like attendance numbers. The document recommends writing outcomes and associated measurable indicators, then evaluating programs and services using data, observations, surveys, etc. to demonstrate impact. Measuring outcomes can help justify funding, defend programs, and tell the story of how the library benefits the community.
The document discusses using percentages and equations to solve percent problems. It provides examples of finding the percent, part, or whole given information about two of the quantities. It also gives examples of writing and solving equations to determine commission earned from sales, royalty amounts, and results of a survey where the part and percent are known.
The document discusses calculating markups and discounts for retail stores.
It provides examples of calculating markups based on a store's cost and its percentage markup. For a music store with a 67% markup, a CD that costs $10.50 would have a $6.80 markup.
It also discusses calculating discounts, with an example of a 20% discount on an item originally priced at $39.95 resulting in a sale price of $31.96 using either a two-step method or a one-step method.
The document concludes with assignment problems for the reader to complete related to these markup and discount calculations.
This document provides examples and explanations for calculating percent of increase and percent of decrease. It defines percent of change as the amount of change divided by the original amount. Several examples are given of calculating the percent of increase or decrease in different scenarios. These include finding the percent increase from 4 to 7.5 (87.5%), the annual increase in video game production from 1960 to 1990 (about 133%), and the percent decrease when a computer costs dropped from $875 to $745 (14%).
This document provides instructions for converting between fractions, decimals, and percentages. It explains that a percentage is a ratio comparing a number to 100. To convert a percentage to a decimal, write it as a fraction over 100 and divide. Several examples are provided to demonstrate converting between fractions, decimals, and percentages.
The document defines prime numbers, composite numbers, and prime factorization. It provides examples of prime and composite numbers. It then explains how to perform prime factorization by writing a number as the product of its prime factors using a factor tree method in multiple steps.
1. The document provides examples of how to solve subtraction problems using regrouping or "borrowing" when the numbers in a column cannot be directly subtracted.
2. It explains that when subtraction is not possible in one column, you can "borrow" from the column to the left by decreasing its value by 1 and increasing the value of the column directly to its right by 10.
3. This process is demonstrated through step-by-step examples of subtracting multi-digit numbers like 745 - 527 and 621 - 345.
The document discusses scientific notation, which is a way of writing numbers using powers of 10. It explains how to write numbers in scientific notation by moving the decimal point to place it between the 1 and 10, and using the number of places moved as the exponent. It also covers how to convert between scientific notation and standard notation, compare numbers in scientific notation, and perform calculations such as multiplication using scientific notation.

The document concludes with a word problem about arranging choral students in rows.
This document provides an overview of exponents and exponential notation:
- Exponents show repeated multiplication, with the base being the factor and the exponent showing how many times the base is multiplied by itself.
- Exponential notation compactly writes repeated multiplication, such as 2^6 representing 2 x 2 x 2 x 2 x 2 x 2.
- Negative integers raised to an even power are positive, while raised to an odd power are negative.
- A word problem example calculates 10^3 = 10 x 10 x 10 = 1,000.
- Order of operations must be followed when evaluating expressions with exponents.
This document discusses key concepts in simplifying algebraic expressions:
1) Any expression separated by addition or subtraction is a term. A term with no variable is a constant, and any number multiplying a variable is its coefficient.
2) Terms with identical variables and exponents are like terms. To simplify an expression, like terms can be combined by adding or subtracting them.
3) An example problem walks through identifying coefficients, like terms, and constants in expressions and combining like terms using the distributive property.
The document explains the distributive property, which states that multiplying a sum or difference by a number is equivalent to multiplying each term in the sum or difference by that number. It provides examples of using the distributive property to simplify multiplication problems, including with variables. It also explains using the distributive property "backwards" by first distributing and then combining like terms.
The document discusses properties of numbers including commutative, associative, identity properties of addition and multiplication. It provides examples of applying these properties to simplify calculations mentally. Specifically, it explains that the commutative property allows changing the order of numbers when adding or multiplying, and the associative property allows changing the grouping of numbers when adding or multiplying. It also notes that the identity for addition is 0 and for multiplication is 1.
This document discusses inductive reasoning and the process of making conjectures based on patterns. It explains that inductive reasoning involves making observations about a pattern, forming a conjecture to describe the pattern, and writing a rule to explain the pattern. It provides examples of patterns and questions to help observe patterns and write the corresponding rules. The document also discusses using counter-examples to determine if a conjecture is correct or incorrect.
This document summarizes rules for multiplying and dividing integers:
1) When multiplying integers with the same sign, the product is positive. When multiplying integers with different signs, the product is negative.
2) The rules for dividing integers are the same as for multiplying - a positive result for same signs, negative result for different signs. Division by zero is undefined.
3) Students are instructed to complete worksheet problems on multiplying and dividing integers, focusing on even-numbered problems.
