An example will be given to the class as to how we use the thermometer to calculate temperature. The teacher will take one student's temperature, the thermometer might register 97.5 of and teacher will demonstrate in this way that normal average temperature is being expressed as a decimal on the real life. The teacher will mention that in order to measure fractions and decimals we have to divide the unit of measurement into many equal parts. Usually, we can choose the number of total parts into which a unit is divided. We can expect to find fractions with any numbers of equal parts.
Decimals are easier to add, subtract, multiply and divide.
As part of the assessment, the students will watch 2 of their favorite TV programs and find out using a clock, how much time is devoted to commercials. Each student should time in minutes the whole program as well as each commercial from beginning to end. The student will compare number of minutes spent on commercials versus the time of the whole program and express the results in fraction and decimal form and compare the fraction and decimal to determine which program devotes more time to commercials.
