This set of lessons (2) is designed to be used over a week-long period. These lessons use an engaging picnic context to help 1st graders master Common Core Standard 1.G.3 "Partition circles and rectangles into two and four equal shares, describe the shares using the words halves, fourths, and quarters, and use the phrases half of, fourth of, and quarter of. Describe the whole as two of, or four of the shares. Understand for these examples that decomposing into more equal shares creates smaller shares." These lessons also provide teachers research on what partitioning is and how this standard was meant to be taught.
