Today’s Task
1. Choose a set of pyramid cards, choose the set that will
move your learning on.
2. Work out the expressions which go in each box of the
pyramid.
3. If you can, write an equation for the final box.
4. If you can, solve the equation to find the value of the
unknown number.
Today’s Task
When choosing a set of pyramids, remember to
choose the set that will move your learning on.
