In the textbook , Exercise 388 typically involves working with coordinates on a number line or coordinate plane, depending on the grade level. Below are the solutions for the most common editions. Grade 5: Number Line and Coordinates
Identify the distance between marked points (e.g., ) to find the value of one grid cell. If cells represent unit, then each cell is 2. Find the points Point A : If it is cells from , its coordinate is Point B : If it is cells past , its coordinate is Answer: The coordinates are typically represented as
In the 6th-grade curriculum, number 388 often requires plotting points in a four-quadrant coordinate system to form a geometric shape. Mark the coordinates on the axes. For example:
Could you please confirm (5th or 6th) you are in so I can provide the exact step-by-step calculation for your version?
Connecting these specific points usually forms a rectangle . 3. Calculate Perimeter/Area Length : Width : Area : square units. Answer: The resulting figure is a rectangle with an area of
The task usually asks you to determine the coordinates of points or to place points on a number ray based on given distances.
