Max Maths, Year 5, Learn together, Time review (2)

In a Year 5 mathematics lesson, students are reviewing the concept of time and how to convert between different units, such as minutes to seconds and hours to minutes. The lesson includes a practical exercise using a conversion table to help students understand the relationship between these units. For instance, they learn to calculate the number of seconds in 4 minutes and 21 seconds. The conversion table shows that 1 minute is equal to 60 seconds, so 4 minutes equates to 240 seconds. By adding the additional 21 seconds, students find that 4 minutes and 21 seconds total 261 seconds.

Another part of the lesson involves converting a larger time unit into a smaller one, specifically from hours to minutes. The conversion table is used again to illustrate that 1 hour is equivalent to 60 minutes. To convert 2 hours and 55 minutes into just minutes, students can use two different methods. One approach is to note that 2 hours and 55 minutes is 5 minutes short of 3 hours, which is 180 minutes, resulting in a total of 175 minutes. Alternatively, they can calculate directly by recognizing that 2 hours is 120 minutes and then simply adding the 55 minutes to reach the same total of 175 minutes. These exercises help solidify the students' understanding of time conversion and arithmetic skills.
