It’s that awkward time of day – maybe your lesson wrapped up quicker than expected, you had a shift in your schedule, or you just need a way to keep students engaged before the chaos of dismissal. Whatever the reason, those extra 10 minutes can either feel like wasted time or become a valuable opportunity for extra math practice.
The best part? You don’t need anything fancy to make the most of it. Here are some low-prep math activities that are easy to implement, require little to no materials, and actually get kids thinking!
Activity #1 – Skip Counting Challenge
This is a quick and easy mental math activity that builds fluency with multiplication patterns.
📢 How to Play:
- Pick a starting number and a skip-counting pattern (e.g., “Let’s count by 4s starting at 12!”)
- Have students say the numbers out loud, one at a time around the room.
- Keep going as high as possible OR switch up the pattern (counting backward always adds an extra challenge for my kiddos!)
Why it works: This game reinforces multiplication and number patterns in a fun and interactive way. (Students also love to beat other classes OR their own record!)
Activity #2 – The 24 Game (NO Cards Needed!)
You might know the classic 24 Game, where students use four numbers and basic operations to make 24. Bud did you know you can play without any special cards?
📢 How to Play:
- Randomly write four numbers on the board (like 3, 5, 7, and 8!)
- Challenge students to use addition, subtraction, multiplication, or division to make 24. Older students can even use parentheses and the order of operations to create 24!
- Let them share different solutions with each other – there’s often more than one way to make 24!
Why it works: This activity strengthens problem-solving and mental math skills, while keeping students actively engaged and talking about math!
Activity #3 – “I’m Thinking of a Number…”
This is my GO-TO “game” that my students beg to play; while it feels like a game, it’s secretly a number sense workout for their brains!
📢 How to Play:
- Think of a number and give students clues to figure it out. Here are some of my favorites:
- “It’s a multiple of 6.”
- “It’s greater than 30, but less than 60.”
- “It has 4 factor pairs.”
- “The sum of the digits is 9.”
- Have students write their guesses on whiteboards or raise their hands to answer.
- The student who gets it right can pick the next mystery number!
Why it works: The possibilites are truly ENDLESS with this activity, and it reinforces factors, multiples, place value, and even logical thinking!
Activity #4 – Math “Would You Rather” Stretches
Combine movement with math for an energy-boosting brain break!
📢 How to Play:
- Call our two choices and assign movements to each. Keep them basic or make them relevant to what you have been teaching recently. Here are two of my favorites:
- “Would you rather have 12 dimes or 5 quarters?” (Jump for dimes, touch toes for quarters)
- “Would you rather multiply by 2 or by 3?” (Hop on one foot for 2, spin for 3)
- Students pick an answer and do the movement while you reveal the “best” choice (if there is one!)
Why it works: These stretches keep kids moving while reinforcing or reviewing an endless possibility of math topcis.
Activity #5 – The Silent Multiplication Game
When my third grade group was getting rowdy mastering their multiplication facts, we played this game to keep things calm in the classroom!
📢 How to Play:
- Pick a multiplication fact set (e.g., 7 times tables).
- The first student says a fact out loud (“3 x 7 = 21”).
- The next student silently holds up fingers for a different fact (6 fingers would mean “6 x 7”).
- Another student says the answer out loud.
- Continue until all facts are covered!
Why it works: This is a fun, low-stress way to practice multiplication facts while keeping the class quiet and focused. I also would use this during my teacher table during small groups for my students to gain multiple opportunities to recall their facts.
Activity #6 – Math Pictionary
If you are in your geometry unit (or really any unit!), turn the math vocabulary into a quick sketching game!
📢 How to Play:
- Write a list of math terms on index cards (words could include: parallel lines, line plot, sum, perimeter, array, obtuse angle, etc.)
- A student picks a word and draws it on the board while the rest of the class guesses!
Why it works: It challenges your students to visualize the many math vocabulary words they learn in a year … plus, it’s seriously the ultimate no prep game.
Activity #7 – One-Minute Estimation
Create fun, real-world estimation within the four walls of your classroom!
📢 How to Play:
- Choose an object in the classroom (e.g., box of markers, the height of the whiteboard, etc.)
- Have students estimate the number by asking, “How many ___ do you think are in ___?” Set the timer for one minute – all students must enter their estimates before the time goes off!
- Then, count and compare to see who had the closest estimate.
Why it works: This activity will build your students’ estimation skills and gets students thinking about numbers in real-life contexts.
Activity #8 – The 60-Second Math Challenge
This math challenge is another favorite of my students! Build fluency with any math skill in this activity.
📢 How to Play:
- Give students one minute to complete a quick challenge, such as:
- Write as many multiples of 6 as you can.
- Write five equivalent fractions for 1/2.
- List all the factors of 36.
- Solve as many addition problems as possible.
Students love trying to beat their personal best each time!
Why it works: This builds fluency and confidence without it feeling like a drill!
Final Thoughts
Those extra 10 minutes don’t have to feel like wasted time! With these low-prep math activities, you can reinforce key skills, keep students engaged, and have a little fun – without any extra work on your part.
