One of my favourite stories is Roxaboxen, by Barbara Cooney.
It is about a group of children who play pretend and use all of the
things in their environment to add to their play.
A few days after reading the story, we were learning about fact families.
Once you know one fact...you really know 4.

We decided to take our math outside and build fact family houses, using things
from nature to add to our learning...just like in the story.
'I'm just building a part of the house...'
'Let's use shells...'
'we can add jewels...'
'we need rocks and boxes...just like in the story...'
'we used 3, 6, and 9...'
'You do the adding ones and I'll do the subtracting ones...'
'Can we use a box...just like in Roxaboxen?'
'we used 2, 4, 6 and the wind keeps blowing our stuff!!!'
'we have 4, 5, and 9...'
Great way to practice our math and enjoy the beautiful fall weather!
