Second grade mathematicians just began a new unit in math focused on fractions. We began with creating and naming equal parts. The students were taught that a fraction is part of a whole. They learned that the top number in a fraction is called the numerator and tells how many equal pieces there are. The bottom number is called the denominator and tells how many pieces make up the whole thing. They can remember that the denominator is the bottom number because it is downstairs. The students shared different ways of folding paper into equal shares and will participate in many fun fraction activities. It is easy to use food as examples when discussing how to share equally. For example, what are the ways we could divide a pizza in half so that there are two equal pieces? What happens when there are four friends sharing the pie? Second grade friends are thrilled to begin working with this sophisticated math concept.
