GCF and LCM Problem Solving
This document discusses when to use the greatest common factor (GCF) or least common multiple (LCM) to solve word problems. It provides examples of GCF and LCM problems and then presents 6 sample word problems, asking the reader to identify whether each uses GCF or LCM. The document also provides the answers, identifying problems 1, 2, and 6 as GCF problems and problems 3, 4, and 5 as LCM problems. It includes additional examples of GCF and LCM word problems.
The Associative Property
The document discusses three mathematical properties: the associative property, which allows changing the grouping of operations without changing the result; the commutative property, which allows changing the order of operations without changing the result; and the distributive property, which distributes multiplication over addition or subtraction. It provides examples of how to use each property to solve problems involving areas, discounts, and total costs.

1) The steps of long division are: Does (divide), McDonalds (multiply), Sell (subtract), Cheese (check), and Burgers (bring down).
2) For each step: determine how many times the divisor goes into the first part of the dividend (Does), multiply and write the product below (McDonalds), subtract the product from the dividend (Sell), check if the difference is less than the divisor (Cheese), then bring down the next digit (Burgers).
3) If the difference is zero and there are no more digits, the problem is solved.
Monkeyin' Around With Long Division
Long division is a method for dividing one number by another. It involves repeatedly subtracting the divisor from the dividend. The key steps are: (1) divide - determine how many times the divisor goes into the first digit of the dividend; (2) multiply - multiply the divisor by the answer; (3) subtract - subtract the product from the dividend; (4) bring down - bring down the next digit if there are any remaining; (5) repeat steps 1-4 or take the remainder. For example, in the long division problem 56/5, the steps are followed to get an answer of 11 with a remainder of 1.
Prime and Composite Numbers
Prime numbers are numbers that can only be divided by one and themselves, with two being the only even prime number. Composite numbers have more than two factors, like six which can be expressed as 6x1 and 3x2, making it a composite number rather than a prime number. Students should practice identifying factors of different numbers with parents or teachers to understand the difference between prime and composite numbers.

The document discusses the least common multiple (LCM) and how it can be used to find common denominators when adding or comparing fractions. It explains that the LCM is the smallest number that is a multiple of both numbers being considered. If the numbers are prime, their LCM is found by multiplying them together. Examples are provided to illustrate calculating the LCM of various number pairs and groups.
6-2 Multiplying Decimals by Whole Numbers
The document discusses the benefits of exercise for mental health. Regular physical activity can help reduce anxiety and depression and improve mood and cognitive functioning. Exercise boosts blood flow and levels of neurotransmitters and endorphins which elevate and stabilize mood.
Long Division
Long division is explained using a family as an analogy to represent the steps.

The document then walks through a long division problem step-by-step using this personification analogy to illustrate each part of the long division process.
Prime and composite numbers
A prime number is a number that is only divisible by 1 and itself, with examples being 2 and 3. A composite number has more than two factors, such as 4 and 6. Co-prime numbers only have 1 as a common factor, so prime numbers such as 35 and 39 are also co-prime numbers since they only share 1 as a common factor.

Place value
Place value is represented in standard, expanded, and word forms. Standard form is the usual way numbers are written, while expanded form writes them as sums of each place value. Word form writes out numbers as words like two hundred three and four hundred fifteen.
Geometryvocab
This document defines various geometry terms including:
1) Line segments have two endpoints and are part of a line. Lines go on forever in both directions with no beginning or end. Rays have one endpoint and go in one direction forever.
2) Angles are formed by two rays that share a common endpoint. There are right, acute, and obtuse angles.
