Math Unit #4 - Coordinate Geometries & Reading and Interpreting Graphs

This is the 4th unit for Math. As you can see how the unit is named, we learnt about coordinates, how to read and interpret graphs, and make graphs. This is a useful and interesting unit for me as I haven't really learnt or go deep into coordinates yet. It was also a review about graphs for me. And how graphs are misused is quite interesting. We learnt:

1. Reading Maps
2. Coordinates and the Number Plane
3. Introducing Straight Line Graphs
4. Graphing Straight Lines
5. Lines Parallel to the Axes
6. Further Graphing

1. Graphs and Their Features
2. Reading Graphs
3. Drawing Graphs
4. Travel Graphs
5. Misuse of Graphs

We learnt a lot in this unit.

• We learnt how to find places using the grids on the map and the coordinates on provided.
• We learnt how to write the coordinate of a place on the map.
• We learnt about the number plane.
• We learnt how to find a point on the number plane, and how to find the coordinate from the point.
• We learnt how to draw a slope from an equation, and form an equation from the slope.
• We learnt what are the lines parallel to the axes, and how to draw them from the equation.
• We learnt the point to intersection of lines.

• We learnt the divided bar graph, the sector graph, the line graph, the conversion graph, and the step graph and their features and what they're used for.
• We learnt how to read them, interpret them, and get different informations from them.
• We learnt how to draw the different graphs using the information given.
• We learnt how to choose the most suitable graph for different kinds of information and data.
• We specifically looked at the travel graphs, and how to read them.
• We learnt how to find out the misusing parts of a graph.
