In springtime, you and your students might like to explore math in the great outdoors. Here are some ideas.
Look at a tree and try to estimate its circumference and its diameter, and then figure out how to measure it.

What is the ratio of a trees height to its circumference? Does it vary for different species of trees or for trees of different ages?
Guess how many blades of grass might be encircled by a large rubber band dropped casually on a playing field, and then get down on your hands and knees and start counting!
Lie on your back and watch a cloud moving past, and try to predict how long it will take to finish passing a treetop... then start a stopwatch!
Measure your shadow at different times of day.
Try to locate the largest and smallest blooms on a flowering bush or in a garden bed, estimate their dimensions, and then measure and compare them.
Children as young as kindergarten can learn to enter data in spreadsheets (or record daily numbers in a list). You can help your students set up a spreadsheet to record data and display it with a simple graph that automatically will reflect changes when you update the data. What sorts of data? Here are just a few ideas from an endless supply of possibilities:
Does your school yard have any space for a new playground? The opportunities for using math abound as students design a possible playground to fit the space.
Your students can be math detectives as your class takes a walk around the school yard or through the neighborhood.
