Practice the Number 20 at Home (No Screens Needed!)

The best learning happens through play. Here are a few simple, screen-free ideas to continue your number 20 adventure together and celebrate this big number.

The '20 Questions' Game

This is a classic game of logic and deduction that is perfect for this number. One person thinks of an object, animal, or person. The other players have up to twenty 'yes' or 'no' questions to guess what it is. This game is a brilliant workout for the brain. It teaches children how to ask good, strategic questions, how to use logic to eliminate possibilities, and the importance of listening carefully to the answers. It’s a truly engaging, screen-free game that fosters communication and critical thinking.

Two-by-Ten Lego Tower

This is a great hands-on activity for understanding that twenty is made of two groups of ten. You'll need at least twenty LEGO bricks. The challenge is to build two separate, identical towers that are each exactly ten bricks tall. Then, you can place them side-by-side to see the full group of twenty. This provides a very strong and concrete visual representation of '2 x 10 = 20'. It’s a playful, hands-on way to introduce the concepts of multiplication and place value.

20-Second Tidy-Up Bursts

This is a practical life skills activity that connects the number twenty to a quick, focused effort. Instead of a long, daunting clean-up, try doing '20-second tidy-up bursts'. Set a timer and challenge your child (and yourself!) to put away as many things as possible in twenty seconds. You can do several bursts throughout the day. This game teaches the power of focused effort and that even a small amount of time can make a big difference. It turns a chore into a fun, high-energy game while practicing counting to twenty.
