A double number line is very similar to a ratio table in that you use them to solve problems requiring proportions. The ratio table is more flexible in that you do not need to position the numbers in the "correct" position. If you Google using models in realistic mathematics education you will find references to these and ideas how they might be used in the classroom

How many lines of symmetry does a plolygon have?
It depends on how many sides that it has and whether of not it is regular (all the lines of the polygon are of equal length if it is a regular polygon). For regular polygons, the number of symmetry lines is the number of sides if number of sides is an odd number. Otherwise, the number of symmetry lines is double the number of sides. A square has 4 sides and 8 symmetry lines; a triangle has 3 sides and 3 symmetry lines.
How are perpendicular lines and intersecting line alike?
Perpendicular lines are lines that intersect each other at 90 degrees or at right angles
How are perpendicular lines and intersecting lines alike and how are they different?
Some intersecting lines are perpendicular lines.Take any old pair of intersecting lines. If the angles at the intersectionhappen to be 90 degree angles, then the lines are perpendicular lines.
How are perpendicular lines and intersecting lines alike and different?
they both have lines crossing each other which make angles. perpendicular lines make right angles while intersecting lines make other kinds
Why do number lines have numbers in them?
Because if they did not, then they would not be number lines!
Parallel lines?
rable
How are intersecting lines alike to perpendicular lines?
intersecting lines are alike because perpendicular lines have to intersect to be perpendicular. 2: They are the same because they touch another line so they are the same.
How are lines of latitude and lines of longitute alike?
lines of latitude and lines of longitude are the same because they just are.
What are vertical lines called?
They are simply just called lines.
How are perpendicular lines and intersecting lines alike How are they different?
They are alike because they both cross each other. They are different because perpendicular lines have to be a right angle while intersecting lines can be any kind of angle.
How are the contours of the water table different from normal contour lines?
The contours of the water table lines are the same as the contours of other topographical lines. The only indication of water tables might be elevation lines but they are not unique to water tables.
How are perpindicular lines alike to intersecting lines?
Perpendicular lines are lines that intersect at a right angle (90 degrees).
How many lines of symmetry does a plolygon have?

What Is Alike Between Axis and Equator?
They Are Both Imaginary Lines.
How are perpendicular lines and intersecting line alike?
Perpendicular lines are lines that intersect each other at 90 degrees or at right angles
How perpendicular lines and parallel lines alike?
Well, they are used for graphing information on graphs and are used on maps.
How do you use multiplication tables?
Choose one number from the side and highlight it accross Choose one number from the top and highlight down the row Where your two lines meet is the answer 3 X 2 = 6
