3rd Grade Math | Unit 7
$5.00
In this unit, students reason about attributes of two-dimensional shapes, calculate area and learn about perimeter. Students learn to classify broader categories of shapes (quadrilaterals and triangles) into more specific sub-categories based on their attributes. For instance, they study examples and non-examples of rhombuses, rectangles, and squares, and come to recognize their specific attributes. Students also expand their knowledge about attributes that can be measured. In this unit, students learn the meaning of perimeter and find the perimeter of shapes. They consider geometric attributes of shapes (such as opposite sides having the same length) that can help them find perimeter. As the lessons progress, they consider situations that involve perimeter, and then those that involve both perimeter and area. These lessons aim to distinguish the two attributes (which are commonly confused) and reinforce that perimeter measures length or distance (in length units) and area measures the amount of space covered by a shape (in square units). At the end of the unit, students solve problems in a variety of contexts. They apply what they learn about geometric attributes of shapes, perimeter, and area, to design a park, a West African wax print pattern, and a robot. They then solve problems within the context of their design.

Here is a comment from a customer…
Karen E. said: “OK, at first I thought “Really? I’m going to pay for graphic organizers that I can probably find for free with some searching, etc?” Well, now I am so glad that I did. So good to have organizers available quickly BUT also several of them have variations which is helpful for “seeing” how to use them in my content area. Good value.“
