Big Ideas: Decimals can be compared based on their size. Decimals can be compared by analyzing like place values. Previous grade level expectations required students to be able to show decimal numbers using fractional notation. Students were also required to compare decimals to the hundredths. This lesson builds on the understanding of the value of each digit within a decimal number. This lesson requires students to understand how to compare decimal numbers using basketball players' free throw percentages. This comparison to the thousandths provides students with the ability to later compute with decimal numbers in order to determine the reasonableness of their answers. Vocabulary: compare, decimal, decimal place value, expanded form, hundredths, symbol, tenths, thousandths, word form Special Materials: Use the website below to choose other players of interest for your students. http://www.basketball-reference.com/leaders/ft_pct_career.html
