Bicycles and Tricycles
Three-year-olds are developing their large motor skills and bicycles or tricycles can make this happen. Younger children will need a tricycle because they may still be too small even for a toddler-size bicycle. As your child approaches 4, he may enjoy a "big boy" bicycle--with training wheels. Put the training wheels an inch off the ground to encourage him to learn the balance necessary for riding without themm.
Balls
The American Academy of Pediatrics (AAP) says that some of the most important gross motor skill milestones for 3-year-olds involve balls--kicking, throwing and catching them. A regular large bouncy ball will work well, but if your child enjoys a particular sport, you may want to get that ball. Consider playing outdoor games that include a velcro ball with a felt catcher.
Language Learning Toys
At age 3, the window of language-learning opportunity is open. It's much easier for a child to learn a second--or third--foreign language than it is for an adult. Look for toys that promote foreign-language learning. For example, you can find electronic toys with a language switch that allows kids to play with the toy in English or Spanish. You can also opt for electronic workbooks that teach foreign languages.
Craft Kits
Craft kits allow children to focus on their fine motor skills. Look for ones that will give your child the opportunity to use scissors--mastering scissors is an important milestone for 3-year-olds. Kids also can paint pottery, build things with clay or paint pictures to develop these skills.
Board Games
Learning colors, counting, basic phonics and vocabulary are some of the intellectual skills that 3-year-olds need to master. Simple board games can make this happen. Candy Land, for example, teaches colors, while concentration games can teach the alphabet or opposites.
Imaginative Toys
Youngsters learn to develop social and emotional skills through imaginative play and story telling, according to the AAP. Seek toys that encourage this, such as dress-up clothes, dolls and puppets.
