Have students plot the three numbers on a scaled number line.Example 3Give students time to read the information in the problem.“Interpret what it means for 150of the population to live in Escambia county.” Listen for an understanding that one in every 50 Floridians lives in Escambia.Extension:“If there were 100 Floridians, how many would live in Escambia?” 2 “If there were 1000 Floridians, how many would live in Escambia?” 20Discuss the columns of the table. Note that the decimals and percents are easier to compare than the fractions.This is a good assessment of a student’s readiness for the homework.ClosureComplete this table of benchmark numbers.Fraction14310122512032071034151Decimal0.250.30.50.40.050.150.70.750.21Percent25%30%50%40%5%15%70%75%20%100%Differentiated InstructionKinestheticSome students have difficulty seeing that 60% is not only equal to “60 out of 100,” but also equal to “6 out of 10” and “3 out of 5.” Give students three 100-grid squares. In the first grid have students shade 60 out of 100 squares. With the second grid have students draw thick lines around groups of 10 squares and then shade 6 of the groups. With the third grid have students draw thick lines around groups of 20 squares and then shade 3 of the groups. When students compare all three grids they should see that the same amount of 60 squares have been shaded on each of the grids. This can be seen easily if the students have grouped the squares by rows or columns.3. You made the most shots.4.
