These eight lessons will ask students to compare the value of two numbers using the "less than" and "greater than" signs. Students will order decimals by graphing on a number line, solve problems by adding, subtracting or multiplying decimal numbers and solve problems involving rates, average speed, distance, and time using multiplication of decimals. Students will be able to calculate and solve problems using division of decimals by whole numbers and decimals. By the end of this unit students will be able to calculate and solve addition, subtraction, multiplication and division problems arising from concrete situations. STUDENT WORKSHEETS, an EDUCATOR GUIDE, and a UNIT WRAP UP for assessing student performance after completing this unit are included.
