Half

We've been working on the concept of half, but I'm sorry to say dear readers, I couldn't think of a practical activity for outdoors.  Maybe some of you can?  If you do have ideas, feel free to post a comment.  If I was in a more woodsy outdoor area, I suppose we could have filled up some containers half full with acorns, pine cones etc.  What do you think?

Measuring

We've been measuring with non-standard units.  The children have collected leaves and ordered them according to size.  They drew lines with sidewalk chalk and then found objects longer and shorter.  We also used leaves to find things longer and shorter.  For problem solving, which we do at least once a week (often more) we worked out how to measure our outdoor area using our footsteps, we all looked at the concept of estimating too.
