Very useful and adaptable. You can use these 28 cards as a SCOOT activity, put them in a science center, or use the TIC TAC TOE gameboard and instructions for a class/team competition. These are formatted much like the GRADE 5 STAAR SCIENCE TEST. The cards have two parts. The first part contains the information and the question. The second part of the card gives you a multiple choice answer. You can use with or without the multiple choice answer secton. They cover categories 2 and 3 of the STAAR test, which includes Earth Science and Force and Motion. There are lots of illustrations, a student sheet, and an answer key. Enjoy the easy and quick way these can be used. Also good questions for NGSS.
