  1. Motor Math (4-3-1) Monday Rational Numbers March 19, 2012 SPI 2.3 Use rational numbers and roots of perfect squares/cubes to solve contextual problems. SPI 2.2 Compare rational numbers using appropriate inequality symbols. SPI 2.4 Determine the approximate location of square/cube roots on a number line. A triangle has an area of 13 ft2. How big would a similar triangle be if you used a scale factor of 6? The area of a square playground is 900 meters. What is the length of each side? Which inequality symbol would make this number sentence true: ? What is the GCF between and ? Area = 81 in.2

  2. EXIT 12E EXIT RAMP Which of the following inequality symbols, will make this number sentence true? A. < C. > B. = D. + EXIT ONLY

  3. Motor Math (4-3-2) Tuesday Using Rational Numbers March 20, 2012 SPI 2.3 Use rational numbers and roots of perfect squares/cubes to solve contextual problems. SPI 2.5 Solve contextual problems that involve operations with integers. If you stacked a cube with a volume of 216 ft3 on a cube with a volume of 729 ft3, how high would they reach? There are five puppies in a litter. They weigh 2.4 pounds, 3.5 pounds, 2.7 pounds, 3.1 pounds, and 3.2 pounds. The heaviest puppy is adopted by a neighbor. How much do the remaining puppies weigh all together? Area = 81 in.2

  4. EXIT 12E EXIT RAMP The temperature dropped 4° each day for 5 days. If the temperature dropped 2°F on the first day, what was the temperature 5 days later? EXIT ONLY

  5. Motor Math (4-3-3) Wednesday Ratio, %, & Proportions March 21, 2012 SPI 1.1 Use proportional reasoning to solve mix/conc. problems. SPI 2.6 Express the ratio between 2 quantities as a %, & a % as a ratio… SPI 2.7 Use ratios and proportions to solve problems. The rectangular prisms are similar. What is the ratio of the volume of the smaller prism to the volume of the larger prism? What is the scale factor? Of the 95 counties in TN, 33 are in East TN. About what percent of counties are in East TN? 2mm 3mm 6mm 9mm 4mm 12mm Area = 81 in.2

  6. EXIT 12E EXIT RAMP One hundred-forty seventh-graders are going on a field trip to the National Civil Rights Museum. The ratio of chaperones to students must be 1:10. How many chaperones are needed for the trip? EXIT ONLY

  7. Motor Math (4-3-4) Thursday Simplifying Expressions March 22, 2012 SPI 2.1 Simplify numerical expressions involving rational numbers. A scientist has a 80 mL of a solution that is 5% salt by weight. She adds 20 mL of a solution that is 3% salt by weight. What percent salt is the resulting solution? Javon is dividing 2.5 pounds of almonds equally among 3 friends and himself. How many pounds of almonds will each person get? Sue made a square quilt that covered 81 ft2. How much fringe does she need to go around it? Area = 81 in.2

  8. EXIT 12E EXIT RAMP Simplify the following expression: EXIT ONLY
