Secondary areas of developmen

  • Social : Draws upon own capacity for attention and memory


  • Cognitive : Draws upon own capacity for attention and memory
  • Emotional: Explores autonomy


  • Language : Interacts verbally and non-verbally


  • Physical and motor: Discriminates by using their senses




Prerequisites : Every child in your class should know at least one song.

Matériel nécessaire

  • An interactive whiteboard, a computer, a tablet or a smartphone


  • A small classroom object that is easy to hide
  • Install the Mazaam app and open the World of Lynx (intensity)


Lesson plan

Setting the scene

1. Introduce the activity :

“Today, we’re going to play at finding a small hidden object. The soft and loud sounds will give us clues to where the object is hidden.”

2. Stimulate the children’s memories

By asking them questions about the soft or loud levels of intensity they explored in the previous module: The Musical Detective – Part 1.

For example :

  • Sing the opening words of a song the children know, first softly and then loudly. And then ask them: «What’s the difference between these two ways of singing?”


  • Sing softly: “If I sing like this, am I singing softly or loudly?”


  •  Sing loudly: “If I sing like this, am I singing softly or loudly?”»


1. Getting ready:

  • Ask the children to sit in a circle on the floor. The circle should be large enough for individual children to move around easily within it.


  •  Ask the children to suggest a song that they’ve already learned.


  •  Sing the song as a group to ensure that the children have memorized both the tune and the words.

2. Explain how the game is played :

Tell the children that they will have to sing to guide the detective to find the hidden object :                                                                      

  • “We’ll sing softer and softer as the detective moves away from the object.”


  • “We’ll sing louder and louder as the detective gets closer to it.”

3. Give a demonstration :

Give the small object to one of the children and ask them to hide it between their crossed legs. Explain that this child is the keeper of the object.                                                                                               

  • Explain that you’ll be the detective this time.


  • Ask the children to sing the song softer and softer as you move away from the object, then louder and louder as you get closer and finally get to the object.

4. Play the game :

  • Choose a first child to play the role of the detective, and ask them to go away and close their eyes.


  • Explain that you’re going to give the object to a keeper who’ll hide it between their crossed legs.


  • Once the object is hidden, ask the detective to move around inside the circle to find it.


  • Sing the first notes of the song with the group so that the children guide the detective by the intensity (softer or louder) of their singing.


  • Once the detective has found the object, do the exercise again by choosing another detective and another keeper.

To go further

Repeat the exercise with other songs the group knows.

Hide the object somewhere else in the classroom. (There’s no keeper in this version of the game.)

Include sound intensities (soft/ loud) when learning new songs. For example, ask the children to sing the song’s chorus loudly and the verses softly.

Play the second game in the Mazaam app’s World of Lynx with the children.
