Gypsum is one of the more common minerals in sedimentary environments. It is a major rock forming mineral that produces massive beds, usually from precipitation out of highly saline waters. Since it forms easily from saline water, gypsum can have many inclusions of other minerals and even trapped bubbles of air and water.
STAR Math is a terrific mathematics assessment program especially if you already use the Accelerated Math program. The broad range of skills that it accesses is appropriate for getting valuable information to drive your mathematics instruction. Math intervention is behind when compared to reading intervention overall.
