Slide Deck

Odd or Even Adventure

Welcome 2nd Graders! Today we’re going on an exciting number adventure to learn about odd and even numbers.

Introduce the lesson and set a fun, welcoming tone. Explain that today's adventure is all about numbers and deciding if they're odd or even.

What Are Odd and Even Numbers?

Even numbers: Can be divided into two equal groups (like 2, 4, 6).
Odd numbers: Have one extra (like 1, 3, 5).
Can you think of some even and odd numbers?

Explain the concept of odd and even numbers. Use simple language and examples to introduce the idea that even numbers can be split into equal pairs, while odd numbers have an extra one.

Group Activity: Sorting the Numbers

  1. Get into small groups.
  2. Each group gets a set of number cards.
  3. Sort the cards into two piles: odd and even.
  4. Discuss and share why you placed each number in its pile.

Outline the group activity instructions. Remind teachers to circulate among groups to assist and ask prompting questions.

Quick Assessment

Examples:

  • Is 7 odd or even?
  • Is 8 odd or even?
    Share your answers and reasoning with the class!

Introduce the quick assessment. Prompt students with examples and encourage participation to check for understanding.

Great Job!

You did amazing! Now you know the difference between odd and even numbers.
Keep practicing and exploring numbers every day!

Wrap up the lesson with a brief recap and encouragement. Emphasize the importance of understanding numbers.

Activity

Odd and Even Sorting Activity

Welcome to the "Odd and Even Sorting" activity! This activity is designed to help you work in small groups to sort number cards into odd and even categories. Let's get started on our number adventure!

Activity Instructions

  1. Group Formation: Form small groups of 3-4 students. Make sure every group has a set of number cards.

  2. Sorting Task: In your group, carefully look at each number card. Decide if the number is odd (has one number left over when divided into pairs) or even (can be divided into two equal groups).

    • Place all odd number cards in one pile.
    • Place all even number cards in another pile.

  3. Discussion: Once your cards are sorted, discuss with your group:

    • Why did you decide that a particular number was odd or even?
    • Can you come up with another example of an odd or even number?

  4. Sharing: After your group is done, each group will share one example of an odd number and one example of an even number with the class. Explain your reasoning!




Teacher Follow-Up Points

  • Walk around the classroom to observe each group's discussion and offer guidance if needed.
  • Ask guiding questions such as:
    • "What makes a number odd?"
    • "How can we tell if a number is even?"
    • "Can someone explain why [a specific number] belongs in the odd/even pile?"







Reflection

After the activity, take a minute to think about the following:

  • How did sorting the number cards help you understand odd and even numbers better?
  • What was one thing you learned from your group's discussion?












Great job everyone! Keep practicing at home and remember that numbers are everywhere, so keep exploring and sorting them out.
