Study Notes
Basic Fractions
- A fraction represents a part of a whole.
- The numerator is the number of shaded or unshaded pieces.
- The denominator is the total number of pieces.
- Zero can never be a denominator.
Mixed Numbers and Improper Fractions
- Mixed numbers have a whole number part and a fraction part.
- To convert a mixed number to an improper fraction: Multiply the denominator by the whole number, then add the numerator. The denominator does not change.
- To convert an improper fraction to a mixed number: Divide the numerator by the denominator. The dividend becomes the whole number, the remainder the numerator and the denominator does not change.
Equivalent Fractions
- To create equivalent fractions, multiply or divide the numerator and denominator by the same number.
Adding Fractions
- Add the numerators and keep the denominator the same. Ensure a common denominator before adding.
Multiplying Fractions
- Multiply the numerators to get the new numerator.
- Multiply the denominators to get the new denominator.
- Simplify the answer when possible.
Dividing Fractions
- Invert the second fraction (flip the numerator and denominator).
- Multiply the fractions as usual.
Geometry Formulas
- Perimeter (P): The distance around a two-dimensional figure.
- Area (A): The amount of space inside a two-dimensional figure.
- Volume (V): The amount of space a three-dimensional figure occupies. (volume = length x width x height)
Operations with Decimals
- Adding/Subtracting Decimals: Line up the decimal points and add/subtract as usual, then bring the decimal straight down.
- Multiplying Decimals: Multiply as usual, then count the digits behind the decimals in the problem to decide how many digits to place behind the decimal in the answer.
- Dividing Decimals: Move the decimal in the divisor to make it a whole number. Then move the decimal in the dividend by the same number of places. Divide as usual.
Measurement Conversions
- Know the common conversions between units of measurement (e.g., inches to feet, feet to yards, etc., meters to kilometers, etc.)
Rounding
- Students should be able to explain and reason about rounding.
- Understand place value.
- Use a number line to help with rounding.
- The digits to the right of the rounding digit change to zero.
- If the rounding digit is 5 or greater, add 1 to the digit to the left.
Order of Operations
- Use the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction) to determine the order of operations.
Data Analysis (Line Plots)
- Displays data on a number line.
- Shows the frequency of data values.
Algebraic Thinking
- Understand and apply the order of operations
- Solve simple expressions
Multiplying and Dividing Whole Numbers
- Apply Standard Algorithm
- Solve simple word problems.
Comparing Numbers
- Compare the digits from left to right to decide which number is larger.
Multiplying and Dividing decimals
- apply area model, partial products, etc.
- apply appropriate algorithms to obtain the correct answers.
