Term 2, week 4 - Maths


Task description

Dear Year 7s,

Here is your independant learning task for the week and some instructions:

  • Find the measurements like you’re spying on the shape’s secret life.

  • Use the right formula or the Maths Police will issue you a “Confusion Warning.”

  • Show your working so your future self doesn’t scream, “WHAT WAS I DOING?!”

  • Check your answer—if the area is bigger than Earth, try again.

  • Write it neatly, because ancient archaeologists should not be needed to decode your maths.

    Have fun!
