What students practice
Count squares and outside edges on grids, split composite figures into rectangles, find each piece's area, and add for the whole. Then find perimeter from printed sides, choose a split, work with T shapes, solve area and perimeter stories, and subtract a notch from an enclosing rectangle. Area Code and Mixed Review finish the packet.

Labeled Composites: Area


Take Away a Notch
What's inside
- p. 3
Count the Squares
Count the squares to find the area, and count the unit edges to find the perimeter.
- p. 4
Split It
Find the area of each piece, then add to find the area of the whole shape.
- p. 5
Labeled Composites: Area
Every length is in centimeters; find each piece, then add for the whole area.
- p. 6
Labeled Composites: Perimeter
Add the lengths of all the sides to find the perimeter of each shape.
- p. 7
Choose Your Split
Split each shape into two rectangles any way you like, then find the area.
- p. 8
T Shapes
Every length is in meters; split each T into a bar and a stem, then find the area.
- p. 9
Area and Perimeter Together
Every length is in centimeters; find the area and the perimeter of each shape.
- p. 10
Composite Stories 1
Read each problem, find the area, and show your thinking in the box.

Solve problems involving area and perimeter of composite rectangles involving whole numbers with known side lengths.
In this packet: pages 3 to 14. 4.GSR.8.3 practice in all our packets
Who it's for
Grade 4 lessons on composite rectangles with known whole-number side lengths. Every outline side of every labeled figure is given. Units are centimeters, meters, and plain units. U shapes appear on Take Away a Notch; worked keys use the whole rectangle minus the notch. The 26-page packet has 36 items, 12 practice pages, 12 matching keys, a cover, and a teacher page.
