Study Notes

Multiplication Vocabulary

  • Product: The result of multiplying two or more numbers together.
  • Partial product: A part of the product, often calculated by multiplying a single digit of one number with the entire second number.
  • Decompose: Breaking down a number into its individual parts, such as hundreds, tens, and ones.
  • Property: A rule or characteristic that applies to numbers and operations, such as the commutative or distributive properties.
  • Distributive property: A property that allows multiplying a single number by multiple addends, such as 3(x + 4) = 3x + 12.
  • Area model: A visual representation of a multiplication problem, where the area of a rectangle is used to represent the product.
  • Array: A set of objects arranged in rows and columns, used to represent multiplication.
  • Place value: The value of a digit based on its position in a number, such as hundreds, tens, or ones.
  • Factor: A number that divides another number exactly, such as 3 is a factor of 12.
  • Column: A vertical arrangement of objects or numbers, often used in multiplication.
  • Row: A horizontal arrangement of objects or numbers, often used in multiplication.
  • Horizontal: A direction or arrangement of objects from left to right.
  • Vertical: A direction or arrangement of objects from top to bottom.
  • Equation: A statement that two expressions are equal, such as 2x = 6.
  • Digit: A single symbol or numeral in a number, such as 1, 2, or 3.
  • Two-digit: A number with two digits, such as 14 or 27.
  • Multi-digit: A number with more than two digits, such as 345 or 1024.
  • Multiplier: A number that is being multiplied by another number.
  • Multiplicand: A number that is being multiplied by another number.
  • Strategy: A method or approach used to solve a problem, such as using the distributive property or area model.

Multiplying Two-Digit Numbers

Place Value

  • In a two-digit number, the left digit represents groups of 10 (tens place) and the right digit represents individual units (ones place)
  • Understanding the place value of each digit is crucial for multiplying two-digit numbers

Partial Products Method

  • Multiply each digit of one factor by each digit of the other factor to find the partial products
  • Calculate partial products by multiplying:
    • Tens place by tens place
    • Tens place by ones place
    • Ones place by tens place
    • Ones place by ones place
  • Add up the partial products to find the final product
  • Example: 14 × 23 = 200 + 30 + 80 + 12 = 322
