Zach and Kayla have run out of credit, and must collect diamonds to keep building their virtual city. But they don鈥檛 have much time, as they want to enter Neon City into an imminent virtual city competition!

They can earn diamonds by answering questions correctly. Ada asks the questions, which all require them to convert from one time measurement unit to another.

The first question requires them to convert five days into hours. They use a bar model to help them. The next question involves converting minutes to seconds, and the next converting weeks to days.

This short animated film is from the 91热爆 Teach series, Neon City: Measurement and Geometry.

Teacher notes

Before watching

Download/print an A4 activity sheet for this episode (PDF, 91KB). See link below for answers.

Activity sheet - units of time

You might want to check children鈥檚 prior learning around units of time, with questions such as:

  • How many months are there in a year?
  • How many days in a week?
  • How many weeks in a year?
  • How many hours/minutes/seconds in a day?

During the film

You may want to pause the film while the children are answering each question, to allow your pupils to work the answers out themselves, or to ensure understanding of the bar model and how it represents the question.

After watching

You could give the children opportunities to practise their fluency with converting between different units, for example by completing a table with a number of conversions, such as:

HoursMinutesSeconds
16060 x 60 =
7200
300

You could then give them some reasoning and problem solving questions based on the type tackled in this episode, such as; Kayla finished the race in 4 minutes 20 seconds and Zach finished it in 245 seconds. Which child finished the race first?

You could ask your pupils to come up with some similar problems for a partner to solve.
