Brain Teasers for Kids

Ideas for Teachers

Math Brain Teasers:

If you’re a teacher looking for a fun way to teach math, brain teasers and puzzles are a good place to start. Brain teasers with an appropriate level of difficulty can help your class think of math as a fun activity and even look forward to the next lesson. Use these tips to implement brain teasers in your classroom.

  • You can start math class every day with a quick brain teaser to get students’ attention and help them focus on the subject with a good attitude. You can even make a competition of it, handing out prizes to the first student to finish, which will encourage everyone to work faster and thus prevent wasting too much class time on the introductory activity.
  • If you have short math classes and can’t spare time every day, you can still schedule it in once per week as a treat, or do it on a different day each week.
  • During a guided practice activity, you can hand out a puzzle worksheet to those students who regularly finish first and need an additional challenge.
  • You can assign brain teaser puzzles to be completed outside of class as a make-up assignment or for extra credit work.

Other Brain Teasers:

Brain teasers are less likely to align with other subjects such as social studies, but there are still several legitimate ways to use them outside of math class.

  1. You can hand them out to students on their way home as a reward for good behavior.
  2. If your class is mature enough that this won’t disrupt instruction time, post a riddle or puzzle on the board each day and offer a “reward” (such as a small piece of candy) to anyone who solves it that day.
  3. Any brain teasers that reference curriculum content may be used as “enrichment” activities (for gifted students who aren’t challenged enough by normal coursework and need more variety of assignments), since they encourage critical thinking skills.
  4. Stash a few stacks of these with your other worksheets in your “sub folder,” as one of the activities to be used when your class has a substitute teacher who doesn’t know the curriculum content.


Easy-to-print resources can often be found on printable worksheet websites, such as those listed here.

Ideas for Parents

Here are some ideas for implementing critical thinking, activity worksheet, and just for fun brain teasers for kids.

Form a New Habit

Solving riddles and logic puzzles can be a fun family activity to do together; but even better, it can improve your child’s cognition and perhaps even grades. You can make this a routine activity in your house by printing out a set of riddles at the beginning of each week. Facilitate the routine by taking the following steps:

  • Set aside a folder or three-ring binder to hold the riddles and brain teasers. The solved ones can be archived in the same binder or a separate one depending on preference.
  • Designate a time and place for the brain teaser activity. For example, you may want to keep the folder in the kitchen and work on the activities every morning during breakfast (or just after, if there’s time before school).
  • Let your child get involved in the routine. He or she could be assigned to read the brain teaser out loud for the whole family each morning. If you have another child, it could be his or her job to pass out pencils whenever they’re needed.
  • Print out enough riddles and brain teasers for each week in advance and clearly mark which one is to be solved each day.
  • Set a reminder on your phone so you won’t forget the activity in the rush of getting breakfast in the morning. It takes about a month for a habit to form, so after a while it will get easier to remember your new routine.

Other Uses

If you just don’t have time in the day to add a routine, you may want to use your folder full of brain teasers in one of these ways instead:

  • Store it in the car so that your child can work on puzzles and riddles during long car rides.
  • Take it in to the doctor’s or dentist’s office with your child to keep his or her mind off the upcoming appointment.
  • Use it as an incentive for good behavior. Reward your children by allowing them to play some of the brain teasers when they’ve behaved well.
  • Take the folder along to formal events, such as a church service or a wedding, when your children are expected to sit still and you don’t want them to distract others by playing games on a phone.
  • Find some fun educational worksheets to slip in as well. If you’re lucky, your children will enjoy them, learn something from them, and not notice the difference.
