What is Measurement ? – a number that indicates a comparison between the attribute of the object (situation or event) being measured and the same attribute of a given unit of measure. means the attribute being measured is “filled”, or “covered”, with a unit of measure with the same attribute. ________________
What is van Hiele level? A model that feature five levels of hierarchy of ways of understand spatial ideas. 0. Visualization 1. Analysis 2. Informal Deduction 3. Deduction 4. Rigor
What is “Shape of Date”? Another name for data analysis.
What is independent event? Occurrence or non occurrence of one event has no effect on the another example would be rolling the dice
What is Three Stages of Development about Measurement? Stage 1- measuring with self, length of arm, hand, body Tied closely to children’s exploration of spatial relationships/ development of spatial sense. Stage 2- measuring with non-standard units/tools (unifix cubes, paperclips, fruitloops) Links concepts of measurement with concepts of numbers. Stage 3- measuring with standard units (centimeters, inches, grams, ounces). Children who have measured objects with unifix cubes can draw the object on centimeter paper.
What is four geometric strands? 1.Shapes and properties 2.Location 3.Transformation 4.Visualization
What is a circle graph? Graphs that show percentages 0 sibling 1 sibling 2 sibling 3 sibling
What is experimental probability? Probability is the measure of the chance of a event occurring
What Critical Conditions for Effective Measure? Need to measure exactly without leaving gaps or overlapping. The need to count the units of measurement carefully without skipping. The inverse relationship between size of the measurement unit and final count. The importance of using a meaningful unit of measurement.
What is Shapes and Properties? When children work with two and three dimensional. What makes a shape alike and different they covered is.
What is Data Analysis? A sense of how data are spread out or grouped. What characteristics about the data set as a whole can be describe. What the data tells us in a global way about the population from which they are taken.
What is theoretical probability ? Is a activity with an unfair game
What is Three Basic Elements When Teaching Measurement? Hands-on measurement activities Reflection about process and results Comparison and discussion of results
What is location? Specify location and describe spatial relationship using coordinate geometry and other representation systems.
What is a Data Graph ? a bar graph or picture graph use for illustrating data over time, height, weight over age, and percentages.
What is simulations? Is a technique use for answering real world question or making decisions in a complex situations where a element of chance is involved.
what are three main steps? 1.that you wish to measure. 2.Choose Select an attribute of something an appropriate unit of measurement. 3.Determine the number of units.
What is transformation? Are the changing in position or size of the shape.
What is Stem and leaf plots ? Are form of bar graph in which numeric data are graph.
What is dependent event? It a occurrence of a event when the second event dependent on result of the first event.
What is Visualization ? Might be called “geometry done with the mind’s eye.” Able to create mental images of shapes
