Bring math home with this interative estimating worksheet! Scholars make educated guesses about the number of six household items: crayons in a crayon box, keys on a key ring, coins in a piggy bank, trees in the yard, pictures on the...

In this sunspots and climate change learning exercise, learners use a diagram of a tree stump and its rings to determine the age of the tree. They use sunspot data from the internet and they construct an Excel spreadsheet to compare the...

Students investigate the age of trees by analyzing tree rings.  In this dendocronology lesson, students examine sample images of tree rings and identify their age by the amount of rings.  Students complete a chart identifying...

Students examine how the environment influences tree growth. In this tree activity, students analyze the growth of rings to see how plants adjust to adverse conditions in order to survive.

Students examine how to plan for prudent use of trees so that we never run out of this natural resource. They determine what the oldest wooden object in their home is and draw picture of it. They observe a cross section of a tree and...

Students discover how to estimate the age of redwood trees. They measure the trees' diameters by using string to calculate the circumferences. Students conclude by discussing the science of dendrochronolgy.

Learners examine how the circumference, diameter, and the relationship of Pi of a circle are related. They count the summer rings of a tree to determine its growth.

In this subtraction worksheet, 2nd graders examine three pictures of apple trees. They use the apple numbers to answer 4 problems.
