ThanksGiving Table for Fourteen: Composite Figures

Eighteen guests are coming for Thanksgiving, but there are only four folding tables! Grade 6 students arrange them in a line, a block and an L, then find the perimeter, seats and tablecloth area of each. They discover that area stays the same while perimeter changes. Interactive, auto-graded, 22 questions. Aligned to 6.G.A.1. About 25 minutes.

Table for Eighteen: A Thanksgiving Area and Perimeter Worksheet for 6th Grade


Eighteen people are coming to Thanksgiving dinner, and your family has just four folding tables. Can you arrange them so everyone gets a seat? In this interactive, real-world math worksheet, students solve a problem every family faces on Thanksgiving: setting up the table. The tool they use is area and perimeter of composite shapes.


What students do


  • Part A: The Long Line. Push all four 6 ft by 2½ ft tables end to end. Find the total length, the perimeter, how many chairs fit (2 ft of edge per chair), and how much tablecloth is needed.
  • Part B: The Block. Push the tables into a 2 by 2 block. Find its length, width, perimeter, seats and area.
  • Part C: The L. Arrange the tables in an L shape. Work out the two missing edge lengths, then find the perimeter and seats. Find the tablecloth area by splitting the L into two rectangles.
  • Part D: What Did You Notice? Compare the three layouts and explain why the area never changes while the perimeter, and the number of seats, does.
  • Part E: Eight More Guests! Now 26 people are coming. Choose a layout, prove whether it seats everyone, and discover that the L falls short by exactly one seat.


Why teachers love it


  • Standards-aligned: built for CCSS 6.G.A.1. Students find the area of composite figures by decomposing them into rectangles and solve real-world perimeter problems.
  • Interactive drawings: each layout is a live diagram. Dimension labels fill in, outlines turn green, chairs appear around the table and the tablecloth spreads out as students get answers right.
  • Auto-graded with instant feedback: every answer is checked right away, so students can spot and fix mistakes as they work.
  • The big idea that sticks: same area, different perimeter. Students see that pushing tables together hides edges and loses seats, a concept many students never connect to real life.
  • Ready to use: 22 questions, about 25 minutes, with a hint on the first problem and a teacher-friendly layout.


Perfect for


  • 6th grade geometry units on area and perimeter
  • November math lessons around Thanksgiving
  • Review of composite figures and decomposing shapes
  • Independent practice, math centers, sub plans or the week before break
  • Advanced 5th graders or 7th grade review


Skills covered: perimeter of rectangles and composite figures, area of rectangles, decomposing composite shapes, missing side lengths, working with fractions and mixed numbers (2½ ft), rounding down in context, comparing area and perimeter, and real-world problem solving.

Learning Objective

Students arrange the same four tables into different layouts and find the perimeter, seating and tablecloth area of each, splitting the L-shape into rectangles to find its area. They discover that the area stays the same while the perimeter, and so the number of seats, changes when edges are pushed together. This builds fluency with area and perimeter of composite figures in a real context (6.G.A.1).
