Vocabulary

  • Decimal: A number that uses place value and a decimal point to show values less than one, such as tenths and hundredths

  • Place Value: The value of a digit in a number

  • Standard Algorithm: A way of setting out a step-by-step mathematical procedure

  • Rounding: To find the nearest ten, hundred, or thousand (and so on). For example, 391 rounds up to 400 and 331 rounds down to 300

  • Digit: A symbol used to show a number

  • Power of 10: When one of the factors is a multiple of ten, you can use place value patterns and basic facts to find the product

  • Product: The result (answer) of multiplying a set of numbers together.

  • Quotient: The result (answer) of dividing two numbers.

  • Estimate: To find a number close to an exact amount.

  • Operations: Addition, Subtraction, Multiplication, Division

Activities At Home

  • Create number cubes or spinners and have the student identify the place value and value of different digits in that number.

  • Roll or pick numbers to create decimals. Add, subtract, multiply, or divide the decimals.

  • Find the batting averages or other statistics in the sports section of a newspaper and add or subtract the statistics.

  • Estimate and find the sums and differences of items at the store and in restaurants.

  • Practice basic addition, subtraction, multiplication and division facts.

  • Roll or pick numbers to create decimals. Compare and order the numbers.

  • Choose a four-digit number. Multiply and divide by powers of 10 (10, 100, 1,000, etc.) by moving the decimal point left or right as appropriate.

Number and Operations - Fractions

What Your Child Will Learn

Standard

Add and subtract fractions with unlike denominators, including mixed numbers (5.NF.1)

Solve addition and subtraction word problems with fractions (5.NF.2)

Solve word problems, understanding that fractions can also be a representation of a division problem
whereas the denominator needs to be divided into a numerator (a/b = a ÷ b) (5.NF.3)

Interpret a fraction as division of the numerator by the denominator (for example, interpret 3/4 as the result of dividing 3 by 4)
Divide fractions to solve word problems (for example, For example, 3 wholes are shared equally among 4 people each person has a share of size ¾)

Multiply a fraction by a whole number and other fractions (5.NF.4)

Understand the relationship between the size of the product and the size of the factors (5.NF.5)

Multiply fractions to solve word problems (5.NF.6)

Divide unit fractions by whole numbers and divide whole numbers by unit fractions (5.NF.7)

Vocabulary

  • Denominator: The number below the line in the fraction. The denominator represents the number of equal pieces the whole is broken into

  • Mixed Number: A number that is made up of a whole number and a fraction

  • Numerator: The number above the line in a fraction. The numerator represents how many pieces of the whole, or how many parts of a set, that are discussed

  • Product: The result (answer) of multiplying a set of numbers together

  • Factor: A number that is multiplied by another (factor x factor = product)

  • Equivalent Fractions: Two or more fractions with the same value. Example: 1/2 = 2/4

  • Improper Fractions: A fraction where the numerator is greater than the denominator.


Activities At Home

  • Create or pick numbers to make fractions. Add, subtract, or simplify the fractions that you find.

  • Find examples of fractions around the house or neighborhood. Add, subtract, multiply, divide or simplify the fractions that you find.

  • Create numbers to use in fractions. Draw these fractions as parts of a whole or set.

  • Use measuring cups when baking or cooking.

  • Identify the use of decimals in sporting events and in newspapers.

  • Draw different shapes. Divide them into different fractions.

  • Practice multiplication and division facts.

Vocabulary

  • Ordered pairs: A pair of numbers where order is important, (4,6) is different to (6,4). Often used to indicate on a coordinate plane, graph, or map.

  • Coordinates: Shown as pairs of letters and/or numbers, e.g. (2,4). Used to show position on a coordinate plane or map.

  • Patterns: A sequence of shapes or numbers that follow a logical rule.

  • Function: A mathematical relationship between two values. The second value depends on (is a function of) the first one.

  • Expression: A mathematical combination of numbers, variables, and operations.

  • Equation: A number sentence with an equal sign. 5 x 4 = 20.


Activities At Home

  • Make up numbers, roll numbers with dice, or find numbers (on labels) and compare them.

  • Create rules (ex. n = 3) and have your student extend the number pattern (3, 6, _ , _).

  • Create a number pattern and have your student write the rule.

  • Create an input/ output machine (function table) for a given rule and have the student fill in the missing Inputs and Outputs.

  • Create an input/ output machine (function table) for an unknown rule and have the student fill in the missing Inputs and Outputs and write the rule.

  • Find numbers and write them in expanded form.

  • Draw pictures and make models of numbers.

  • Volume: The amount of space that a three-dimensional figure contains. Volume is expressed in cubic units, (how many small cubes would fit inside a solid figure).

  • Three-Dimensional Figure: A measure in three directions, such as length and width.

  • Line Plot: A number line long enough to encompass all numbers in the sample, showing a dot or mark over the position corresponding to each number.

  • Mass: A measure of how much matter is in an object.

  • Capacity: How much liquid a container can hold (see volume).

  • Rectangular Prism: A prism with two identical, rectangular bases.

  • Rectangle: A quadrilateral with four right angles and two pairs of opposite equal parallel sides.

  • Right Prism: A solid three-dimensional with two identical, parallel bases. All other faces are rectangles.

  • Base: A side of a polygon or a face of a solid figure by which the figure is measured or named.

Activities At Home

  • Make flash cards of different geometric figures and their properties.

  • Identify different plane and solid figures in your environment.

  • Find the volume of real-world objects in your home.
