 Snapshot of Development: 0 to 6 Months Play: Infants begin by using their eyes to explore toys and then begin to use their hands and mouths to explore. Their play is primarily shaking, banging and mouthing. At the end of this stage, they begin to look for dropped toys and may find a partially hidden object. Communication: Young infants recognize their parents and familiar caregivers. They smile and laugh during playful interactions, such as peek-a-boo. They make early cooing and babbling sounds. Motor: When on their tummies, infants learn to hold their head up and reach for toys. They begin to reach and grasp for objects, beginning with the care-givers clothes and hair and then moving to toys and objects. At the end of this stage, many infants may help hold their own bottle and help bring the bottle to their mouths. They may also begin to take pureed food from a spoon. Materials: Jack in the box , if you don’t have a jack in the box you can also use an empty wipes box with a small toy inside. Note: Small parts create a choking hazard for children. Make sure that all materials you choose to use for an activity or lesson with children meet safety requirements. Small parts are not appropriate for children who are 5 years of age or younger. Interactions: Tummy time is especially important for development of motor skills since the “back to sleep” campaign.  Infants need entertainment during tummy time.  Place the infant on the floor on his or her tummy and place the jack in box in front of the infant.  Activate the jack in the box.  Say “OPEN” when the jack in the box OPENs.  Slowly CLOSE the Jack in the Box and say “CLOSE.”  Repeat as long as the infant is comfortable and happy on her tummy. Snapshot of Development: 6 to 12 Months Play: At the beginning of this stage, play is mostly shaking, banging, and mouthing toys. By the end of this stage, infants begin to combine objects that go together in play. They reach for and hold two objects and may begin to reach for a third. Many infants will look for dropped toys and find partially and completely hidden toys. Many infants enjoy taking things out and putting things into containers. Communication: At this age, infants respond when their name is called. They may turn their head, make eye contact and sometimes smile and vocalize. They may look for family members and pets when called by name. They may respond to simple requests made with gestures, such as, “Come here,” and they may understand “No” or “Stop.” They may lift their arms to be picked up, clap hands, and wave bye-bye. They love to shout and squeal and may be babbling with many different sounds. They may be participating in and sometimes initiating peek-a-boo. Motor: During this stage, many infants begin to sit by themselves and play. They begin to move by rolling, crawling, and cruising. They pick up toys by using a raking motion with their whole hand and by the end of this stage they are using their fingers and thumbs to pick up small objects. They may feed themselves small bits of food. Materials: Pop up Toy, if you don’t have a pop up toy any containers with easy OPEN lids and small toys inside will also work. Note: Small parts create a choking hazard for children. Make sure that all materials you choose to use for an activity or lesson with children meet safety requirements. Small parts are not appropriate for children who are 5 years of age or younger. Interactions: Sit on the floor with the infant.  Sit behind the infant if he or she still needs some support while sitting.  Place the pop-up toy in front of the infant.  Pop up the first door, say “OPEN,” name the character hiding under the door, say “bye-bye and CLOSE.” Show the infant how to CLOSE the door.  Pop-up the second door, say “OPEN”, name the character hiding under the door, assist the infant with hand over hand to CLOSE the door.  Say “bye bye and CLOSE”.  Pop-up the third door, wait a minute to see if they will attempt to CLOSE the door or CLOSE the door themselves.  If not assist again with hand over hand.  Repeat with the fourth and fifth door.    Pop OPEN all the doors saying “OPEN” each time.  Allow the infant to CLOSE all the doors in any order using hand over hand assist if necessary, saying “CLOSE” each time you CLOSE a door. Snapshot of Development: 12 to 18 Months Play: At the beginning of this stage, many infants are imitating the use of everyday objects, such as cups and spoons. This moves into early pretend play where the infant may feed you, or pretend to drink from a cup or eat off of an empty spoon. They also are great imitators and may enjoy imitating daily activities. They may enjoy putting multiple objects in containers and systematically searching for hidden toys and objects. Many infants will pat pictures in books and sometimes vocalize while looking at books. Communication: At the beginning of this stage, many infants begin to respond to one step directions, such as, “Give me the ball.” They may need gestures to help them understand the direction. At the end of this stage, many infants follow a related two-step direction without the help of gestures, such as, “Get the ball and give it to Daddy.” They may be pointing to ask for wants and needs and to ask you to name objects. At around 12 months of age, many infants say 1-3 words on their own and by the end of this stage may say up to 15 or more words. Many infants play turn-taking games at this stage. Motor: At the beginning of this stage, many infants are crawling and cruising to get around, and by the end of this stage, infants are walking with good balance. They may also enjoy walking while carrying large objects and pulling toys. When given a crayon for the first time, they may mouth the crayon or mark the paper. By the end of this stage, many infants are scribbling on paper. They may be starting to scoop food with a spoon and actually get some to their mouths. Infants may also be using a straw or open cup to drink. Materials: Pop up toy, if you don’t have a pop up toy a few containers with easy OPEN lids and small toys inside will also work. Note: Small parts create a choking hazard for children. Make sure that all materials you choose to use for an activity or lesson with children meet safety requirements. Small parts are not appropriate for children who are 5 years of age or younger. Interactions: Sit on the floor with the infant.  Place the pop-up toy in front of the infant.  Pop up the first door, say “OPEN,” name the character hiding under the door, say “bye-bye and CLOSE.” Wait for the infant to CLOSE the door.  Pop-up the second door, say “OPEN”, name the character hiding under the door, wait for the infant to CLOSE the door.  Say “bye bye and CLOSE.”  Repeat with the third, fourth and fifth door.   Leave all the doors closed and allow the infant to attempt to activate the toy.  Give the infant hand over hand assist as necessary.  Pop OPEN all the doors saying “OPEN” each time.  Allow the infant to lead the play saying “OPEN” and “CLOSE” each time the infant opens or closes one of the doors. Reflections on this Lesson How might you teach the math lesson-OPEN and CLOSE during other daily activities and routines? What books do you have in your child care setting, that include the math concept – OPEN and CLOSE? What songs or finger plays do you typically use in your child care setting support the math concept – OPEN and CLOSE?
