17. Measuring With VEX IQBeams 1. How to Measure with a VEX IQBeam VEX IQ Beams have notches which can used to measureobjects Rulers are often used to measure objects, but other objects, like VEX IQ Beams, can also be used to measure. On the sides of the VEX IQ Beams there are notches that are like the lines on a ruler. The distance between each notch is one unit. Grab something nearby, like a book or a pencil, and measure its length to the nearestunit. Interesting Fact: One unit is equal to one half of an inch.

18. 2. Measure the VEX IQGrabber It will take more than one beam to measure theGrabber The VEX IQ Grabber is a tool that can help you reach objects. Imagine trying to grab something on a shelf that is too tall for you to reach. You could use your Grabber to help you reach theobject. Let's measure how much the Grabber improves your reach. Use two 2x20 VEX Beams to measure the length of a fully extendedGrabber.

19. 3.Accuracy A ruler can measure more accurately than a VEX IQBeam You may have noticed that measuring with a VEX IQ Beam is easy, but it is not as accurate as a ruler. Can you think of at least two reasons why measuring with a ruler is more accurate?

20. FindingPerimeter 1. What isPerimeter? This VEX IQ plate has a perimeter of 16units Perimeter is the distance around a shape or object. In the example above, the perimeter of the VEX IQ Plate is 16units.

21. 2. How to Find a VEX IQ Beam'sPerimeter This VEX IQ plate has a perimeter of 16units A shape's perimeter can be found by adding the length of its sides together. In the example above, the length of the plate's sides are 4, 8, 4, and 8units. If we add these numbers together, we can find the plate's perimeter: 8 + 4 + 8 + 4 = 24units.

22. 3. Perimeter of the Alien OceanBoard Find the perimeter of the Alien Ocean Board Previously we learned that a VEX IQ Beam can be used as a measuring tool. Use the notches on the Alien Ocean Board's beams to find the length of each side. Then add the lengths of all four sides to find itsperimeter.

23. FindingArea 1. What isArea? This VEX IQ plate has an area of 16 square units Area is the size of an object or shape's surface. In the example above, the area of the VEX IQ Beam is 16 squareunits.

24. 2. How to Find a VEX IQ Beam'sArea This VEX IQ plate has an area of 32 square units A object's area can be found by multiplying its height and width together. In the example above, the height of the beam is 4 square units, and its width is 8 squareunits. If we multiply these numbers together, we can find the beam's area: 4 x 8 = 32 squareunits.

25. 3. Area of the Alien OceanBoard Find the area of the Alien OceanBoard Previously we learned that a VEX IQ Beam can be used as a measuring tool. Use the notches on the Alien Ocean Board's beams to find its height and width. Then multiply the length by the width to find itsarea.

26. GameSetup 1. Alien Ocean Board and theGrabber To play Land Grab! you will need to build the Grabber and the Alien OceanBoard. The Grabber will be used to pick up Land Units which are VEX IQpieces. The Alien Ocean Board board represents an empty plot of alien ocean that has a perimeter of 44 units and an area of 120 units. Each team will use their board as a platform on which to build an alien islandsettlement.

27. 2. LandUnits Place the 30 VEX IQ pieces listed below in the center of the game field. These pieces represent Land Units that have been submerged deep in the alien ocean. Each team will use their Grabber to pull the Land Units onto their Alien OceanBoards. Hint: Put a 1x1 Connector Pin into each side of the Land Units. This will make them easier to pick up with theGrabber.

29. Area and PerimeterPractice 1. VEX Pieces Are Not PerfectlyRectangular Before we start playing Land Grab!, you may have noticed that the VEX pieces are not rectangular. Therefore, you may be thinking the perimeter and area formulas won’t work! You are right. The formula cannot be applied to roundededges.

30. 2. Estimate IntoRectangles However, the VEX IQ pieces are roughly rectangular in shape. That’s why, for this activity, we willestimate! The area of the first piece is 6 x 1 = 6 square units. The area of the second piece is 6 x 2 = 12 squareunits.

31. 3. Estimating ManyPieces To get the total area of many pieces, you can add them alltogether. Choose any three pieces from the game, and try finding the total area. This total area will be the same no matter which way you arrange those threepieces!

32. 4. FasterEstimate Do you want to be faster than your classmates? Group the pieces together into a giant rectangle. This will give you the same answer, but with less math! You can group them any way you like. Practice this trick by combining at least two pieces that fit into arectangle. Knowing how to group the pieces will help you win LandGrab!

33. LandGrab! 1. Can You Rule thePlanet? Frantic World buildingfun! It is the year 2149. You have traveled to an alien planet far from Earth. The planet is currently just one big ocean, but deep under the water there exists the raw materials to build an island settlement. To rule the planet, your team must use their Grabber and their math skills to build an island settlement that is larger than youropponent's. The game can be played with two teams of 1-4players.

34. 2. TeamRoles The Grabber Operator and a Builder's finishedsettlement Each team consists of a Grabber Operator and one or more Builders. Grabber Operators will use the Grabber to pull raw building materials, called Land Units, out of the alienocean. Builders will use the Land Units to build an island settlement on their Alien Ocean Board. The team that builds the settlement with the larger area or perimeter wins the game and will rule the planet!

35. 3. Pick a Goal: Largest Area orPerimeter? The left board has a larger perimeter; the right board has a largerarea The goal of the game is to build a settlement with either the largest perimeter or area. Before starting the game, the teams need to decide if the winner will be determined by largest perimeter orarea. Important: Make sure both teams understand the goal before starting the game. A game decided by the largest area requires a much different strategy than the largest perimeter game.

36. 4. StartGrabbing! Start the game at the count of three. Each Grabber Operator will begin capturing Land Units. Although there are 30 Land Units available in the center of the alien ocean, each Grabber Operator can only capture 12 of them. Once a Grabber Operator has placed a Land Unit on their Alien Ocean Board it cannot bereturned. Important: Land Units can only be captured with the Grabber. Do not use yourhands!

37. 5. Grab the Right LandUnits The image above shows a strategy for grabbingparts Among the 30 Land Units in the alien ocean, there are 14 Right Angle and 1x Beams that are best for building a settlement with a larger perimeter, and 16 2x Beams that are best for building a settlement with a largerarea. Hint: Grab the 1x and Right Angle Beams if you are trying to build an island settlement with a largerperimeter. Grab the 2x Beams if you are trying to build an island settlement with a largerarea. To win the game you must quickly grab the best Land components before your opponent does!

38. 6. Build Your IslandSettlement This Builder has made an island settlement with a largearea The Builder must use their Land Units to build an island settlement on their Alien Ocean Board. Their goal is to build a settlement with a larger area or perimeter than their opponent. The game can be won by a skilled team even they do not have the best LandUnits. Important: Land Units cannot extend beyond the Alien OceanBoard.

39. 7. Speed Counts but Accuracy CountsMore! Speed and accuracy can increase the size of yoursettlement! After the island settlement has been built, the entire team must work together to quickly calculate the settlement's area or perimeter. The first team to write down their calculation will receive an additional 10 bonus units! More importantly, 20 bonus units will be added to your settlement's size if you have written the correctnumber!

40. 8. Determine theWinner The red team won because their calculation was fast andaccurate! After the teams' settlement areas or perimeters have been calculated, add the bonuses for correct calculations and the fastest team. The team with the larger number wins the game and will rule the planet!

42. Area and Perimeter of the World Fence marks an area with specificperimeter • Using Area andPerimeter • Area and perimeter give you an idea on how much space you have or material you need. This is the first step in almost any project, even the world savingones! • Decorate a room!: A typical room has rectangular floor and walls. By knowing the area of the floor and walls, you will also know exactly how much carpet and wallpaper you need to decorate yourroom. • Get a fence!: Knowing the perimeter of a field helps farmers purchase the exact amount of fence material so they do not wastemoney. • Make an island!: You will need lots of land material to create a new, man-made island in the ocean. Scientists and engineers can figure out how much dirt and sand is needed to make the perfectly sized island. But they need to be very careful. Creating a new island can sometimes harm theenvironment! • Know your enemy!: Knowing the perimeter of the forest can help firefighters figure out how big the fire canbe.

43. Will it fit?: Area and perimeter matter in little things too. To make sure computer chips fit onto the tiniest space, engineers must to know its dimensions andarea.

44. Where We've Seen ScissorLifts A scissor lift being used forconstruction • Reach For theSky! • The Grabber and the scissor lift are very similar devices. Scissor lifts are used in many different professions. They allow workers to reach a variety of different heights as they complete their jobs. In addition, scissor lifts offer a mobile and stable platform to complete work from. They are often used in place of ladders or scaffolding. Their mobility, as well as their stability and security, create a safer and more efficient workenvironment. • Some of the professions below frequently use scissor lifts: ConstructionWorkers • Electricians • Carpenters • WarehouseWorkers • Mechanics
