The Mystery of the Missing Microphones

In groups of four the children have been using the descriptions of the suspects and analysing the clues that have been left behind to solve ‘The Mystery of the Missing Microphones’.

‘Clue 1’ required the group to be able to identify acute and obtuse angles. To solve ‘Clue 2’ each group had to work out calculations presented in word form. ‘Clue 3’ was about using more than, less than and equals signs to compare lengths of time presented in different formats. To solve ‘Clue 4’ the children had to add and subtract fractions with the same denominator. Finally ‘Clue 5’ asked them to solve a range of different calculations and identify the letters that matched up with the answers to eventually find the words that made up the last clue.

Having crossed all of the suspects off their lists that didn’t match the clues they had discovered, each group wrote the name of the suspect they thought committed the crime on a piece of paper and posted it in the box at the front of the class. It was then finally revealed that ‘Lily Leadrole’ was the guilty suspect.

25/5/18 – LO: Today I will become a better mathematician by revising parallel lines, perpendicular lines, types of triangle, types of quadrilateral and lines of symmetry.

After solving a maths mystery that they were given earlier today, in this lesson they were challenged to come up with a maths mystery of their own. They were told that their mystery had to have an ‘Iron Man’ theme. We created a list of suspects using the children’s farmer names and then they were given the ‘to do list’ below concerning their task.

Things you will need to do:

- You will need to write what the mystery is and create a cover page with the title of your mystery on and an explanation of what the mystery is. Maybe one of the suspects is the one who stole the Iron Man's missing ear!

- One of your group will need to create a maths puzzle for 'Clue 1' which will reveal whether the suspect is male or female. This puzzle should be about identifying different triangles.

- One of your group will need to create a maths puzzle for 'Clue 2' which will reveal the suspect's age. This puzzle should be about identifying different quadrilaterals.

- One of your group will need to create a maths puzzle for 'Clue 3' which will reveal the suspect's favourite meal. This puzzle should be about identifying perpendicular and parallel lines.

- One of your group will need to create a maths puzzle for 'Clue 4' which will reveal the suspects shoe size. This puzzle should be about identifying lines of symmetry in polygons.
