Teaching odd and even numbers doesn’t have to be spooky. It can be a lot of fun when you bring in a little Halloween/Fall magic! Second graders love hands-on learning, and October is the perfect time to sneak in themed math practice that feels more lke play than work.

Below you’ll find creative Halloween/Fall odd and even activities aligned with TEKS 2.7A, which asks students to “determine whether a number up to 40 is odd or even using pairings of ebjects to represent the number.”

1. Odd and Even Pumpkin Pairs

Start with a classic visual–pumpkin pairs! Give students small cut-out pumpkins (or mini erasers) and challenge them to pair them up. If every pumpkin has a partner, the number is even. If one pumpkin doesn’t have a match, it’s odd!

This simple, hands-on model makes it easy for students to visualize what it means to have a “pair.”

*Tip for teachers: Let students decorate their pumpkins with stickers or markers to make them unique before pairing them up.

2. Halloween Odd and Even Sorting Mats

Make sorting even more fun with spooky mats labeled “Odd” and “Even.” Students draw Halloween or Fall-themed number cards (1-40), count out the correct number of candy corn, spiders, or cubes, and place them on the correct side.

You can extend the activity by having students record their numbers on a recording sheet or tally up how many odd vs. even numbers they sorted.

3. Odd or Even Mystery Bags

Fill Halloween treat bags with different quantities of items (buttons, eyeball erasers, or mini pumpkins). Students open a bag, count and pair up the objects, then decide if their number is odd or even.

Add a writing extension by having students describe how they knew their number was odd or even–perfect for building math reasoning skills.

4. Halloween Odd and Even Numbers Walk

Add a game with some movement! Tape odd and even number cards around the room. Play Halloween or Fall music and let students “trick-or-treat” or simply “float like leaves” around the classroom. When the music stops, call out “odd” or “even” and students must find a card that matches your call.

This kinesthetic review is a great way to reinforce learning before independent practice or centers.

5. Spider Web Number Sort

Create a large spider web on a bulletin board using string or yarn. Label one side Odd and the other Even. Students draw a number card, decide if it’s odd or even, and attach it to the correct side of the web using a clothespin pin with a plastice or paper spider attached. You may give students a handful of small manipulatives or small plastice spiders that they can use at their desk to create the number of and pair them up to find odd or even.

6. Trick-or-Treat Odd and Even Numbers Scoot

This odd and even review is another fun movement game! Place numbered task cards around the room with Halloween or Fall Festival clip art. Students “trick-or-treat” from station to station with an answer sheet, recording whether each number is odd or even.

Tip: Use glow-in-the-dark pens or blacklight decorations to make it extra fun!

7. Odd and Even Numbers Relay Race

For outdoor fun, line students up in two teams.

Call out a number (or hold up a number card). The first player on each team races to a bucket labeled “Odd” or “Even.” If they get it right, they earn a point for their team!

This active game helps kinesthetic learners solidify number sense while burning some energy. (For more info on other kinesthetic math activities, click here!)

8. Halloween Odd and Even Numbers Lesson, Center, and Assessment

If you’re ready for a complete, done-for-you lesson that ties everything together, this one’s for you!

Students will love this engaging lesson that includes real-world examples and a fun whole group activity that incorporates task cards. Then students will partner up for a hands-on game that will help them solidify this skill with a spooky flair! An assessment is also included so you can see exactly which students need a little more practice!

9. Odd and Even Numbers: Story Problems

Challenge students to solve a short Halloween/Fall themed story problem about odd an even numbers each day. Examples:

• “A witch made 13 spooky cupcakes. Did she make an odd or even number?”
• “There are 24 skeleton bones. Can they be divided evenly between two skeletons?”

Students can write and illustrate their stories to share with the class–a great literacy tie-in!

10. Odd and Even Writing Extension

At the end of your unit, have students reflect in their math journals:

• “What does it mean for a number to be even?”
• “How can you use pairs to prove that a number is odd?”
• “What was your favorite Halloween odd and even activity and why?”

This reflection helps them internalize what they learned about odd and even numbers and gives you a quick informal assessment of their understanding.

Final Thoughts

Halloween math doesn’t have to be scary. It can be filled with laughter, learning, and hands-on engagement. These odd and even activities give second graders the opportunity to practice an important math skill in creative, meaningful ways.
