Vincent and Tara are making triangles with the class construction set. They have a pile of strips of different lengths. How many different triangles can they make?
Getting the Balance
Stage: 1 Challenge Level:
Where are you going to hang the weights on the left-hand side?
What will you need to hang on the right-hand side?
Can you find another weight to balance them with the same weights
on the left?
How will you know you have found all the possibilities?
How are you recording what you've done?
Try out your ideas using the interactive balance, or your school
might have a real balance - ask your teacher.
The NRICH Project aims to enrich the mathematical experiences of all learners. To support this aim, members of the
NRICH team work in a wide range of capacities, including providing professional development for teachers wishing to
embed rich mathematical tasks into everyday classroom practice. More information on many of our other activities
