Benefits of Building Toys

Open-ended toys, like building blocks, encourage your child to develop problem-solving and fine-motor skills (1). The best building toys support your child’s development in multiple ways. Here are a few reasons to purchase building blocks for your child.

Motor Skills

Picking up blocks, pulling them apart, and snapping them together builds finger dexterity. These actions help your child refine both fine and gross motor skills through repetition and precision.

Problem-Solving

Building can be frustrating, but in a good way. Your child will quickly learn that structures tip over if they are not balanced. They learn what fits where and experiment with how to correct structural problems.

Social and Language Skills

Building toys inspire collaborative play. Working together on a tower or castle encourages communication skills and the need for language to explain ideas (2).

Many other skills strengthen through the use of building toys. Children can have fun while learning. Using construction sets is a fantastic way to make that happen (3).

How to Choose Building Toys

When we shop for the best building and construction toys, these are the specific criteria we look for.

Sturdy

Your blocks will likely be dumped out of boxes, thrown, and stepped on. Make sure you choose a building toy that handles rough play without breaking. Inspect your toys frequently to ensure none are damaged or have created sharp edges.

Material

There are great options made of plastic, foam, or wood. Check the product information to ensure the paint and materials are non-toxic and safe for children to touch or chew on (4).

Recognition

Look for pediatrician-approved, organization-recognized, and award-winning products. These accolades often point you toward high-quality toys that deliver on their educational promises.

FAQs

What Is the Most Popular Building Toy?

Mega Bloks is arguably the most popular building toy for little kids due to its interlocking plastic bricks and creative possibilities. It appeals to a wide age range, from young babies to young kids, and comes in various themes and complexity levels.

At What Age Does Constructive Play Begin?

Constructive play typically begins around 18 months to two years of age. Toddlers start to enjoy stacking blocks, fitting pieces together, and building simple structures. It evolves as they grow, becoming more complex and imaginative.

Are Wooden Toys Better for a Child’s Development?

Wooden toys can be beneficial for a child’s development due to their durability and tactile nature. They encourage imagination and are less distracting than electronic toys, allowing children to focus on the play activity itself.

Are Magnetic Building Blocks Safe for Toddlers?

Magnetic building blocks are generally safe for toddlers if they are large enough not to be a choking hazard and if the magnets are securely encased. Always look for high-quality, age-appropriate toys and supervise play to ensure a magnet never comes loose.

Why Are Mega Bloks Good for Toddlers?

Mega Bloks are good for toddlers because they are large, easy to handle, and encourage creativity. The size makes them safe for younger children, and they can be used to teach colors, counting, and pattern recognition.

How Do I Clean Building Blocks?

For plastic blocks like Mega Bloks or Lego, wash them in warm water with mild soap and let them air dry. Wooden blocks should be wiped down with a damp cloth rather than submerged, as soaking can cause the wood to swell or warp.

What Are STEM Toys?

STEM stands for Science, Technology, Engineering, and Math. STEM toys, including many building sets, are designed to encourage skills in these areas. They foster curiosity, logic, and problem-solving through hands-on play.
