Students also research a mathematician on the Internet and make collages of sunflower models that they present to senior citizens. Learning Standards Learn to problem solve, communicate, and reason strategies used in estimating large numbers. Identify and describe a variety of patterns in nature. Classroom Activities Students closely examine a sunflower head filled with seeds and a single sunflower seed. Discuss estimation strategies.
Volunteers measure an area of up to ten seeds and determine total count.
Each student estimates total seeds and records answer on round self-sticking labels. Draw a number line from one to five hundred. Label line at intervals of fifty. Affix labels with estimations on line plot above corresponding numbers. For duplicates, place second label above first estimate.
