Today we talked about fractions as part of sets. (A set is a fancy name for 'group'.) You can figure out fractions with groups of things just like you can make fractions out of a whole. For example, if you have a group of 12 crayons and 5 of them are red, then 5/12 of the crayons are red. The children understood this pretty quickly.
The next step is trickier. We found fractional parts of a set. This is similar to the fractions we've been studying. I reminded the children that when we divide a rectangle into fourths, we divide it into four equal parts. Its the same with a group of things. For example, if you have 9 books and you want to take 1/3 of them, you would split the 9 into 3 equal parts. This of course is division, so to solve it you would divide 9 by 3.
Happy dividing! :o)
