Mathematical puzzles to make and solve
Six matches were lined up in a row as shown
Move two of the matches in this pattern to leave nothing.

This week some of our students will be challenging themselves with their Australian Mathematics Competition Papers. Join them in their enthusiasm by trying to reason out the following:
Whilst sorting out the stationary drawer, Lyn found that 5 glue sticks weighed the same as 2 staplers, and that 3 staplers weighed the same as 20 erasers…
She wondered, how many glue sticks would balance how many erasers?
- 3 glue sticks with 8 erasers
- 3 glue sticks with 50 erasers
- 1 glue stick with 6 erasers
- 3 glue sticks with 17 erasers
- 7 glue sticks with 23 erasers.
Look forward to seeing the drawings and thinkings.
