CHALLENGES IN LEARNING COORDINATE GEOMETRY:
In Coordinate geometry one is supposed to understand geometric aspects in algebra and solve geometric problems. It’s not easy for most of students. Majority of them struggle with using the coordinate points and plotting them between ‘X’ axis of horizontal and ‘Y’ axis of vertical and labelling the points on the grid, connecting the coordinates to make line segment and shapes. More often than not students have no idea of how figure or shape moves up, down, and to the right and left or diagonal without altering the shape in the coordinate plane (transformation).
WHY COORDINATE GEOBOARD?
Coordinate board includes sliding axes of X and Y which divided the plane into 4 parts called as 4 quadrants. Student understand the parts of quadrant, direction of X and Y axis, positive and negative quadrant by adjusting the sliding axes within the board. Determine the line, line segment, and discover how to plot by counting each of pegs and then stretching the rubber band between those pegs to link the two points and labelling the points based on the position within the 4 quadrants. Gradually students learn to determine the distance and section formula and area of geometric shapes by linking the counting pegs between the points. Student discovers concept of transformation by physically flipping or rotating the rubber band from one peg to another within board by same distance and direction without deforming the shapes.
