Connecting Academics & Parents Academic seminars to sharpen
Connecting Academics & Parents Academic seminars to sharpen skills and build understanding in Understanding Perimeter & Area Order the Shapes Covers the largest surface to the smallest surface Allowed: cutting, folding, etc.
NOT allowed: using any type of measuring tool (rulers, tapes etc.) Discuss the strategies you use to order the shapes. Florida Standards for Mathematical Practice (SMP) #1: Make Sense of Problems and Persevere in Solving Them Mathematics Florida Standards Focus Grade 3 MAFS.3.MD.3.5 Recognize area as an attribute of plane figures and understand concepts of area measurement.
MAFS.3.MD.3.6 Measure areas by counting unit squares (square cm, square m, square in, square ft, and improvised units). MAFS.3.MD.3.7 Relate area to the operations of multiplication and addition. MAFS.3.MD.4.8 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. MAFS Learning Progression: Perimeter & Area 6
Copyright 2009 The Dog Pen Adam is creating a dog pen for his dog Tiki. He has 12 yards of fencing to create the dog pen. What could Adams dog pen look like?

Comparing the Problems How do the two questions compare? What were you determining in each problem? Area amount of space inside a region Perimeter the distance around a region Exploring Perimeter with Pentominoes
1. Choose a Pentomino shape. 2. Find the perimeter of the shape. 3. 10 Be prepared to share your strategy for determining
the perimeter. If a child found a perimeter of 5 units for this shape, what was their misconception? If a child found a perimeter of 7 units for this shape, what was their misconception? Copyright 2009
Problem Solving with Perimeter Shanna wants to frame a picture of her pet Riley. Shanna wants to put a frame around the given photo to decorate her home. Whats the perimeter of the picture? 1 2 3 4 5 6 16 7 15 14 8 13 12 11 10 9 Exploring Area
Shanna decided she wants to place the photo of her pet Riley in a photo album. How much space will the photo take up in the photo album? Estimate. Then solve. Complete the Square 1. 2. 3. 4. 5.
Choose a partner, decide which color tile each partner will use to represent their squares. Decide who will go first. Take turns making line segments on the geoboard of any length. Whenever a player completes the fourth side of a unit square, the player places their color tile in the square. Play continues until no more squares can be completed. Winner is the person with the greatest area of the geoboard covered by their color tiles. Relating Perimeter and Area 1.
Read the story problems. 2. Decide if the problem is asking you to find area or perimeter. 3. Place the cards into 2 piles and justify why it was an area or perimeter problem. 4.
Use different strategies to solve the problems. 15 Copyright 2009 Relating Perimeter and Area Create 2 different rectangles that have a perimeter of 24 units. Find the area. Create
2 different rectangles that have an area of 24 square units. Find the perimeter of each shape. What 16 do you notice? Other Examples of Problems in 3rd Grade 17 Finding Area of Rectilinear Figures
18 What strategies would you use to find the area of the below figure? If a student got an area of 52 square meters, what was their misconception? Real World Samples of Area and Perimeter
Take it Home and Try It! Warning: Implementing this engaging activity will result in an increase in motivation and long-lasting learning. DO TRY THIS AT HOME! Purposeful Practice: 1. Pentomino Perimeters 2. Complete the Square 3. Area/Perimeter Sort 4. Area/Perimeter Scavenger Hunt look for objects with a given perimeter/area throughout your home.
5. Design Home Challenge use the given directions to create rooms with objects and dimensions using specific perimeters and areas. 20 Copyright 2009 Possible Delivery Models for CAP Sessions: SCHOOL PARENT NIGHT K-5 School invites parents to a
