Halves and quarters - and thirds also!
In this easy fraction lesson for 1st grade, we don't yet study the fraction notation, but just learn the concepts related to halves, thirds, and fourths (quarters). I show these by coloring in the corresponding parts.
We also compare two given fractions by coloring. It's basically pretty fun! Fractions don't need to be difficult, scary "monsters" at all!
