Math activities can be some of the most fun around. Math games and activities for infants see math at its most basic: numbers and counting. Have the students count objects or people. Show them pictures with many objects in and ask them how many apples, for example, they can find. Even better, get them to count money. Other math activities include measuring things. Have different versions of an object that are similar but of different sizes. Get the students to measure them and see who has the biggest or the smallest.
There are many literacy-based activities for infants. Helping children to read and write their first letters by having them make cards for their families. These can be birthday cards, Christmas cards or Easter cards. Each theme gives you a new excuse to get creative with stickers, crayons and more. Other literacy-based activities can include coloring in letters, circling letter games (write hundreds of letters on a board and get students to circle as many As or Bs as they can). Lastly, you can also read stories to them, using the pictures to help them follow the story.
Art is one of the easiest and most common subjects to teach. It finds its way into most other areas of an infant's curriculum. Most infants just love to draw. Start off with basic ideas like drawing their families and houses, and then move on to drawing exotic animals and mythological creatures. Get more creative with paper plate animals, like lion faces and elephant heads. Other ideas include using crepe paper to make stain glassed windows, making gingerbread men, block painting and making thumb print mice.
If you are lucky enough to have good weather (or snow for snowmen) then also consider a range of outdoor activities. If your schoolyard has enough space, get some blankets or tablecloths and some poles or chairs and make a backyard camp. You can also teach the students hopscotch, have a water fight (be careful), make obstacle courses and even teach them some basic science with a nature walk.
