In this handwriting worksheet, students practice writing the uppercase and lowercase letter X eight times each on the lines provided.

In this letter x worksheet, students practice tracing, then printing the upper and lower case letter x. Students can move a computer mouse over sample letters with guided arrows to begin.

In this printing letter x worksheet, students learn to form upper and lower case Zaner-Bloser letter x. Students trace 20 dotted examples and then practice their own letters on the blank primary lines.

In this letter x printing practice worksheet, learners use their fine motor skills to independently print lowercase x's on the provided lines.

In this geometry worksheet, students identify the coordinate pairs of a segment. They calculate the distance using the distance formula. There are 5 questions with an answer key.

Sixth graders simulate the creation of impact craters on Mars.Through the creation of model surfaces, the effects of an impacting object's mass, velocity and size are determined, and the features of the resulting crater are identified.

One of the first models of DNA appeared to be a triple helix. Young scientists learn about the many scientists who worked to find the shape of DNA. They observe multiple models, tests, and experiments to understand the conclusions. An...
