Definitions for Math K:

(MA.OK.02) Bar graph:

Definition: a graph that uses bars to show information.

Add values: How many children altogether liked either dogs or cats? (5+4=9; Nine children liked either dogs or cats best.)

Compare values: How many more children liked ponies than liked hamsters?

(8-2=6; Six more children liked ponies than liked hamsters.)

(MA.OK.05) Congruence:

            Definition: Geometric shapes that have the same shape and size.

            Example:

(MA.OK.06) Symmetry:

            Definition: A shape, picture, or design that has matching parts when a line is drawn through the middle of it.

            Example:

(MA.OK.07) Visualize transformations of geometric figures:

            Plane figures: "Flat" (2-dimensional) figures formed by curved and/or straight lines, such as circles, rectangles, squares, and triangles.

            Solid Figures: Three dimensional figures, such as spheres, cubes, cylinders, and cones.

            Transformations: Visualizing transformations is being able to pick out congruent figures (those that have the same shape and size) when they are in a different position, such as turned sideways or flipped. Think about how a child moves a puzzle piece to get it to fit. He must slide, turn, or flip it to make it go into its place. Describing figures and visualizing what they look like when they are transformed through rotations or flips or are put together or taken apart in different ways are important aspects of geometry in the lower grades. Students using pattern blocks or interactive computer programs with shapes often have to choose a motion to solve a puzzle.

(MA.OK.07) Visualize combinations of plane figures into solid figures:

            Definition: Visualizing what three-dimensional figure results when you combine various shapes.

            Example: What solid figure results when you combine these plane figures?

(MA.OK.08) Analog and digital clocks:

            Definition: An analog clock shows time by the position of the hands; a digital clock shows time in numerals only.

            Examples: Wall clock are usually analog; clock-radios are usually digital; watches can be either

(MA.OK.10) Non-standard units:

            Definition: Standard units of measure are the established units of English (inches, etc) and Metric (centimeters, etc) non-standard units are the units established by the person doing the measuring.

            Example: How many paper clips long is your foot? It would depend on the length of the paper clip. You could also measure the length of your foot in gummy bears! The paper clips or the gummy bears are non-standard units of measure.

(MA.OK.16) One step oral story problems:

            Definitions: An oral story problem is one that is told rather than read. A story problem that requires one type of computation (only adding or only subtracting) in order to solve it is a one step story problem.

            Example: You say to the student: "I ate one cookie and then I ate two more cookies. How many cookies did I eat in all?" The child only needs to do one computation (adding 1+2) in order to solve the question of how many total cookies were eaten.
