Four-year olds are a bundle of energy. If you don’t give your beloved four-year-old enough toys they will make you their toy.

This is something you don’t want because they may just mess up your settings.

The Best Play for Four Year Olds

Your 4-year-old is likely getting better at problem-solving and has a good handle on how to incorporate a solution that will appease everyone.

While most 4-year-olds can recite the alphabet and memorize shapes and colors, cognitive development isn’t just about learning facts and academic basics. Learning for children this age also envelops learning about learning—how to ask questions and how to process information into understanding.

  • Speech & Language

This age is definitely a chatty one, as more language skills develop (what they say and what they understand) at an astounding rate. Your 4-year-old should have about 2,500-3,000  words they understand. By the fifth birthday, however, it will balloon to over 5,000 words.

Most 4-year-olds love using their imaginations. They may even develop imaginary friends.

Your child may go between reality and pretend play constantly. They might enjoy playing house or dress up, and getting their friends involved, too.

Key Milestones

  • Shows an interest in goal setting for herself—like learning how to ride a two-wheeler, or learning how to pump a swing.
  • Wants to make decisions on their own, such as picking out their own clothing or choosing a snack.
  • Understands the concepts of numbers—that the number four represents four flowers or four balls.

Parenting Tip

To help your 4-year-old continue learning, just keep talking. Answer any questions (even if you don't know the answers), read, and get them thinking about words by asking questions about what you are seeing and doing.

Here are some of the best science experiment kits for kids 4 years old.

Creativity for Kids Grow 'n Glow Terrarium

Creativity for Kids Grow

A terrarium is a miniature garden in a simulated natural environment. The Grow N’ Glow Terrarium is a complete kit for helping kids to create their very own miniature eco-system. It’s so easy! You just assemble, decorate, water and watch it grow. It’s a fun way to teach kids about botany, eco-systems and the life cycle of plants. Kids love to see how things work and especially how the magic of seeds, soil, sun and water will blossom into green plants.

This is a great lesson in cause-and-effect, responsible stewardship and delayed gratification, since the terrarium needs to be misted each day for the seeds to sprout and grow. Like keeping a pet, the plants will only thrive if they’re given water each day – but no worries – if they forget to water it, they learn the importance of water to the life cycle. And when they do water it, the seeds begin to shoot up in 3 to 4 days.

After assembly, there are delightful garden stickers and glow-in-the-dark stars to embellish your terrarium further. During the day, when the terrarium is in full light, it soaks up light for the plants and also soaks up light in the glow stickers. Then at night the stickers will glow and it looks like an enchanted little lightning bug house. The Grow and Glow Terrarium is the perfect STEAM activity that mixes art and science.
