Where is measurement hiding in Just Dance song lengths?

Quick answer

Learning outcome

• You can tell which song is longer or shorter by looking at the time
• You can add up the total time of multiple songs
• You can subtract to find how much longer one song is than another
• You can explain how time works in music and games

Why this matters

How it works

1. Look at the minutes and seconds for each song
2. Compare the minutes first – if one song has more minutes, it's longer
3. If the minutes are the same, compare the seconds – more seconds means a longer song
4. You can add time by adding minutes together and seconds together
5. If seconds add up to more than 60, you need to convert them into minutes

Examples you can see

• Uptown Funk (3:45) is longer than Can't Stop the Feeling (3:32) because 45 seconds is more than 32 seconds
• Shut Up and Dance (3:15) is shorter than Blinding Lights (3:20) because 15 seconds is less than 20 seconds

• Minutes: 3 + 3 = 6 minutes
• Seconds: 45 + 32 = 77 seconds
• Since 77 seconds is more than 60, you need to convert: 77 seconds = 1 minute 17 seconds
• Total time: 6 minutes + 1 minute = 7 minutes, and 17 seconds

Try it as a mini adventure

• Happy Feet – 2 minutes 50 seconds
• Let It Go – 3 minutes 10 seconds
• Dancing Queen – 3 minutes 40 seconds
• Walking on Sunshine – 3 minutes 25 seconds
• Don't Stop Me Now – 3 minutes 35 seconds

1. Start by adding the first two songs:
   • Happy Feet (2:50) + Let It Go (3:10) = ?
   • Minutes: 2 + 3 = 5 minutes
   • Seconds: 50 + 10 = 60 seconds = 1 minute
   • Total: 5 + 1 = 6 minutes
2. Add the third song:
   • 6 minutes + Dancing Queen (3:40) = ?
   • Minutes: 6 + 3 = 9 minutes
   • Seconds: 0 + 40 = 40 seconds
   • Total: 9 minutes 40 seconds
3. Keep trying different combinations until you find 3 songs that make exactly 20 minutes

Common mistakes

• Mistake: Adding seconds and minutes without converting.
  • Why it happens: Forgetting that 60 seconds = 1 minute
  • Fix: Always check if seconds are over 60. If so, divide by 60 to get extra minutes
• Mistake: Comparing only the seconds, not the minutes.
  • Why it happens: Not looking at the whole time
  • Fix: Always compare minutes first, then seconds if minutes are the same
• Mistake: Thinking that 1 minute 59 seconds is longer than 2 minutes 10 seconds.
  • Why it happens: Confusing the order of time
  • Fix: Remember that minutes come first, so 2 minutes is always longer than 1 minute

Parent and carer guide

• Playing Just Dance with your child and asking them to compare song lengths
• Using a timer to see how long songs actually take
• Writing down song times and adding them up together
• Encouraging your child to think about how much time they want to dance
• Playing the "time challenge" game by asking "Which song is longer?" or "How long would 3 songs take?"

• "Let's see which song is longer – can you tell me?"
• "How much longer is Uptown Funk than Dancing Queen?"
• "If we play 2 songs, how long will we dance?"

• It's okay if your child makes mistakes – they're learning!
• Don't rush the process – take time to compare and add up
• Keep it fun and playful – measurement should be exciting, not stressful

Practice questions

1. Which song is longer: 3 minutes 45 seconds or 3 minutes 32 seconds?
2. Add: 2 minutes 30 seconds + 1 minute 45 seconds
3. Subtract: 4 minutes 10 seconds - 2 minutes 25 seconds
4. Which is shorter: 5 minutes 15 seconds or 4 minutes 50 seconds?
5. Add: 3 minutes 20 seconds + 2 minutes 55 seconds

1. 3 minutes 45 seconds is longer
2. 4 minutes 15 seconds
3. 1 minute 45 seconds
4. 4 minutes 50 seconds is shorter
5. 6 minutes 15 seconds

FAQ

What do minutes and seconds mean in music?

Minutes and seconds tell you how long a song is. For example, a song that is 3 minutes 20 seconds long means it takes 3 minutes and 20 seconds to play from start to finish.

How do I add time together?

Add the minutes together, then add the seconds. If the seconds add up to 60 or more, convert them into minutes. For example, 2 minutes 45 seconds + 1 minute 30 seconds = 3 minutes 75 seconds = 4 minutes 15 seconds.

Why is it important to know song lengths?

Knowing song lengths helps you plan how long to dance, decide which songs to play together, and make sure you don't run out of time. It's like planning a journey – you need to know how far you're going!

Can I use this with other games?

Yes! You can use time measurement with any game or activity. For example, you can time how long it takes to build a tower, how long you can hold your breath, or how long a video game level takes.

How can I practice this at home?

Use a timer to track how long you dance, add up the times of different songs, or ask questions like "How much longer is this song than that one?" You can also make up your own Just Dance songs with different lengths and compare them.
