GACE Elementary Education: Practice test II with Verified Answers Graded A+
1. Geoboard A manipulative used to explore basic concepts from geometry such as area,
perimeter.
2. Number sense the ability to understand numbers and their relationships
3. Mode the most frequently occurring score(s) in a distribution
4. Median the middle score in a distribution; half the scores are above it and half are below
it
5. Mean arithmetic average
*a concept of equal distribution*
6. Range the ditterence between the highest and lowest scores in a distribution
7. manipulatives An object which is designed so that a learner can perceive some mathematical
concept by manipulating it
*Examples:* blocks, dominos
8. Geometry rota- a transformation that turns a figure about a fixed point called the center of
tions rotation
The rotations are the same shape and size, but may be turned in ditterent
directions
