Time Problems - PowerPoint

Year 4 students are introduced to the concept of solving time problems by converting between different units of time. The lesson begins with a review of the basic units of time, where students are reminded that 60 seconds make a minute, 60 minutes make an hour, 24 hours make a day, 7 days make a week, 365 days make a year, and 12 months also make a year. Additionally, the concept of a leap year is explained as occurring every 4 years, adding an extra day to February. Students are then encouraged to apply their knowledge to answer questions, such as determining the number of weeks in 14 days, hours in 3 days, months in 1½ years, minutes in 180 seconds, and weeks in 28 days.

Moving on to practical applications, the students tackle word problems that require converting time units. They calculate how long 120 seconds is in minutes, how many days are in 240 hours, and the age of a baby in years and months if they are 19 months old. They also figure out the duration of a spaceman's journey in space for 405 days in terms of years and days. Additional examples include converting a race time of 3 minutes and 20 seconds into seconds, determining the length of a bus journey in minutes and then in hours and minutes, and calculating the duration of a family holiday in weeks and days. The lesson aims to solidify students' understanding of time measurement and conversion through a variety of engaging problems.
