This challenge game consists of 5 categories with 5 questions each. The categories are: igneous rocks, sedimentary rocks, metamorphic rocks, the rock cycle and name that rock. I have used this game as a review of a unit on rocks and my students have always loved playing it.
Important note: Make sure to click on the number value in each box (eg. "200") to ensure slideshow advances to the corrent slide. Clicking on the box may not take you to the correct slide.
