This is the level at which the teacher stretches the student in his thinking and reading. The independent level, on the other hand, is the level at which the child can read easily and with pleasure. Reading scores generally refer to instructional levels.
Snow leopards have long, thick fur, and their base color varies from smoky gray to yellowish tan, with whitish underparts. They have dark grey to black open rosettes on their bodies, with small spots of the same color on their heads and larger spots on their legs and tails.
Height: About 2 feet (.6m) at shoulders. Length: 6-7.5 feet (1.8-2.3m) (includes 40-inch (1m) tail length). Weight: 77-120 lbs (35-55 kg). Female snow leopards are about 30% smaller than males. Lifespan: Their reclusive nature makes it hard to determine snow leopard lifespan in the wild. They have, however, been known to live for as long as 21 years in captivity.
