Reflection: Real World Applications Halves of Cakes and Clocks - Section 3: Making Cakes


It is important that the students label their cake parts with the 1/2 notation.  Students need to understand that each equal part is one of two pieces that make a whole cake. This step is asking students to model with mathematics.  It is expected that mathematically proficient students can apply the mathematics they know to solve problems arising in everyday life, society, and the workplace (CCSS.Math.Practice.MP4)

The CCSS also expect that students can partition circles and rectangles into two and four equal shares, describe the shares using the words halvesfourths, and quarters, and use the phrases half offourth 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 (CCSS.Math.Content.1.G.A.3).
