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 taught the children how to divide their "pizza" in half and make 'half of" it one topping and the other half another topping. Students labeled each side with 1/2 noting that each side had equal shares. They also designed "rugs". These rugs used two halves - triangles or rectangles - to make half of the square also understanding that these decomposed into smaller equal shares. We are "dividing and conquering" the common core standards...pizza anyone?
