Composite Shapes
A shape created with two or more basics shapes is called a composite shape. There are many ways to break down complex (compound) shapes into simpler shapes. The main idea is when we need the area (or volume) of a complex shape, we first break it down into simpler components that we already know about and have easy formulas to describe their attributes. Let's get started!
Math Class Session
These math class lessons will start you out on the right path into our geometry adventure. After watching the math lesson video, continue to practice the concepts using the Geometry Packet, activities, games, projects, word problems... and have fun learning!
Geometry Basics Workbook
We will be using the workbook below for the first four sessions of Geometry to introduce you to the main ideas in geometry. You'll be using one workbook for Sessions #1-4 (download it from Session #1.) You'll also have a small packet to work through that goes into more depth with practice problems. You'll do the workbook pages first, and then dive into the packet.
You will have new workbook pages and a new packet for each session, make sure you complete each one before you move onto the next session. In addition to the content in the workbook, you'll find more videos (below) that cover additional activities, puzzles, and games that you can complete when you've finished the workbook and packets. Let's go!
Geometry Packet: Section 2
This session uses a packet of lessons that we will be working through in place of a regular workbook. We'll be working on different sections of the packet during each session. In addition to the content in the packet, you'll find homework, activities, quizzes, a study guide and a test to complete at the end when you've finished all the content in the entire packet.
Geometry Activity: Solve & Color
This is a fun way to explore the ideas we covered in the packet about area of shapes. Take your time and have fun with these!
Geometry Activity: Spin to Ten
This is a fun way to work through several problems on quadrilateral figures! You get to spin the spinner to decide which problem to do next. Let's get started!
Geometry Game: Composite Figure BINGO
This is a fun activity where YOU get to create your own BINGO board first, then answer questions to figure out if you guessed the answer! The first step is to print out wither the "3-in-a-Row" or the traditional BINGO card for yourself (you need one per player). Next, randomly write the numbers 16 through 40 on the grid, using all the numbers only once and filling in all the spaces (if you're using the 3-in-a-Row board, only choose 9 different numbers between 16 and 40.) You win when you get five (or three) in a row!
Geometry Puzzle: Trading Corks
All you need are two corks (or two marker caps, or two lip balms... something small and cylindrical). Place one in each hand pinched in that part of your hand between between your thumb and index finger (watch video). Reach in to the opposite hand and grasp each cork with a thumb and index finger, and in one swift, easy motion, pull them free. Each hand should now be holding a cork from the opposite hand. You can color your corks with markers so it's obvious that they have traded places!
Geometry Quiz #1
Let's check in and see how much you've learned from the first two sections! First, download the quiz (don't peek at the answer key!) Work through as much of it as you can, and then watch the video below to compare your answers and get a little help if you got stuck.
Geometry Challenge: An Even Fifteen
Using fifteen toothpicks, can you only move two to make three different even number combinations? Watch the video to see how to set up this challenge! (Solutions are posted in the following session at the very bottom of the page.)
