Use coordinates to find a location on a grid.
Locate points in all four quadrants of the coordinate plane.
Recognize which quadrant a point is in, based on the properties of its coordinate pairs.
Understand that the first number in a coordinate pair indicates placement on the x-axis and the second indicates placement on the y-axis.
Coordinate Plane, X-axis, Y-axis, Quadrants, Coordinate Pair
- Students reviewed how to read a coordinate pair and practiced graphing the coordinates
- Students created a map of a zoo using all four quadrants in the grid. They decided where each attraction would be and how big it would be by graphing the coordinate points on the grid.
Techniques and Formulas
Solve problems involving area.
Recognize that area is measured in squared units (i.e., cm2), depicting that the measurement has both height and width.
Find the area of composite figures.
Decompose a composite figure into simple rectangles to compute area.
Use the formula for finding the area of rectangular shapes (A = base x height).
Area, 2D shape, irregular shape
- Students learned area is the measurement of the inside of a 2D shape and practiced finding the area of squares or rectangles using the formula L x H.
- Students practiced finding the area of irregular shapes by sectioning the shape into rectangles to find the area of that section and then adding it all together to find the area of the irregular shape.
Find the area of the shape:
- Can you find sections of rectangles in this shape?
- What is the area of the sectioned rectangles?
