Fraction Timeline

Fifth graders at All Saints’ Episcopal School connect mathematics with their own real-life experiences. Students created a number line labeling whole numbers through their age on their next birthday. We discuss ways in which we can take a whole year and divide it evenly into fractional pieces. Students suggest days (/365), weeks (/52), seasons (/4), and months (/12). Students will think of important events in their lifetime and calculate their exact age at the time of the event. Examples of important events include first day of school, becoming a big brother/sister, a family vacation, meeting a best friend, hitting a homerun, etc. We decided that finding their age to the nearest twelfth (month) would be best, and students will mark fractional parts between each whole number. We note that all of the whole numbers on our number line represent our birthdays (birth month). Fifth graders placed a picture (real or neatly drawn) of each event next to the month and year in which it happened. In addition to the picture, students include the fraction or mixed number and decimal that represents their age at the time of the event. For example: If a student was born in Feb 2012 and made a trip to Colorado in June 2018, they would mark that event as 6 4/12 or 6 1/3 because they were 6 years and 4 months (out of 12) old. Students also included the decimal equivalent of 6.33 and a description. Teachers, students, and visitors on our campus love browsing through the timelines, and they are certainly conversation pieces in the hallway. Fifth graders and families really enjoy this project!
