Students will investigate both standard and nonstandard length and width units, and they will compute and estimate the perimeter by using measurement concepts. Students are going to:
- acknowledge the importance of using standard measurement units for widths and lengths.
- measure items' widths and lengths to the closest half-inch.
- examine and arrange two and three objects according to their respective lengths.
- determine the length and width by using suitable or logical units.
- calculate the perimeter of rectangles on grid paper by counting the units around them.
- calculate the centimeter and inch perimeters of rectangles.
- use grid paper to draw rectangles that represent the given perimeters accurately.
