Chapter 3: Perimeter and Area
Lesson Overview:
1. Perimeter and Area- What are some ways to measure an object's size?
2. Perimeter- How do you find the perimeter of a polygon?
3. Rectilinear Shapes- How do you find the missing side length of a rectilinear shape?
4. Math Meet- will the Little Monsters outscore the Bots?
5. Area- Hoe do you find the area of a rectangle?
6. Lizzie's Notes- How do you find the area of a rectilinear shape?
7. Rep-Tiles- Can you divide any triangle into four smaller copies of itself?
8. Grogg's Notes- Do you know the difference between a reptile and a rep-tile?
Standards Addressed in This Chapter:
3.MD.5- Recognize area as an attribute of a plane figures and nderstand concepts of area measurement.
3.MD.6- Measure areas by counting unit squares (square cm, square m, square in, square ft, and improvised units)
3.MD.7- Relate area to the operations of multiplication and addition.
3.MD.8- Solve real world and mathematical problems involving perimeters of polygons, including finding the perimeter given the side lengths, finding an unknown side length, and exhibiting rectangles with the same perimeter and different areas or with the same area and different perimeters.
3.G.2- Partition shapes into parts with equal areas. Express the area of each part as a unit fraction of the whole. For example, partition a shape into 4 parts with equal area, and describe the area of each part as 1/4 of the area of the shape.
4.NBT.1- Recognize that in a multi-digit whole number, a digit in one place represents ten times what it represents in the place to its right. For example, recognize that 700 / 70 = 10 by applying concepts of place value and division.
