Select even or odd numbers

Learning Objectives Define even and odd numbers using appropriate mathematical language. Identify even and odd numbers from a given set of positive and negative integers. Classify numbers as even or odd by examining their last digit. Predict whether the sum or difference of two numbers will be even or odd without performing the full calculation. Apply the concepts of even and odd numbers to solve simple real-world problems. Explain the divisibility rule for even numbers. Have you ever noticed how numbers can be sorted into two special groups, almost like a secret code? 🤔 Some numbers love to be paired up perfectly, while others always have one left out! Let's unlock this numerical mystery! In this lesson, you will learn how to identify and classify numbers as either e...

TermDefinitionExample Even NumberA whole number that is exactly divisible by 2, leaving no remainder. Its last digit is always 0, 2, 4, 6, or 8.14 is an even number because 14 ÷ 2 = 7 with no remainder. Its last digit is 4. Odd NumberA whole number that is not exactly divisible by 2, meaning it leaves a remainder of 1 when divided by 2. Its last digit is always 1, 3, 5, 7, or 9.27 is an odd number because 27 ÷ 2 = 13 with a remainder of 1. Its last digit is 7. DigitA single symbol used to write numbers (0, 1, 2, 3, 4, 5, 6, 7, 8, 9).In the number 345, the digits are 3, 4, and 5. The last digit is 5. DivisibilityThe ability of one number to be divided by another number without a remainder.10 is divisible by 2 because 10 ÷ 2 = 5 with no remainder. IntegerA whole number (not a fraction) that...

Even Number Identification Rule A number $N$ is even if its last digit is $0, 2, 4, 6,$ or $8$. This rule provides a quick way to determine if any integer, large or small, is even by simply looking at its ones place. It's based on the definition that even numbers are multiples of 2. Odd Number Identification Rule A number $N$ is odd if its last digit is $1, 3, 5, 7,$ or $9$. This rule allows for quick identification of odd numbers by checking their last digit. Odd numbers are numbers that are not multiples of 2. Properties of Even and Odd Sums/Differences $Even \pm Even = Even$ $Odd \pm Odd = Even$ $Even \pm Odd = Odd$ $Odd \pm Even = Odd$ These rules help determine the parity (evenness or oddness) of results from addition or subtraction without performing the f...
