VISUALIZING IN 3D
• Take 3 to 5 Duplo Legos and put them together however you like
• Visualize clear box around your structure
• Draw each side of the “box” on the box template on your table
• Fold and tape into box formation
• Does it resemble actual structure?
DRAWINGS AND COMMUNICATION
• Find someone in the room to trade boxes with
• Can you build each other’s structure?
• What was easy about building the new structure?
• What was difficult about building the new structure?
• What could have improved your build?
ENGINEERS DON’T DRAW ON BOXES
• Let’s find a way to flatten that box
• Shade in the following sides on your box with the crayons at your table:• Top = red• Pick two adjacent sides that also touch the top = Make one blue
and one yellow

PRACTICE ISOMETRIC DRAWINGS
• Cube – 5 x 5 x 5
• Cube – 8 x 8 x 8
• Rectangular Prism – 4 x 3 x 7
• Rectangular Prism – 3 x 9 x 3
• Triangular Prism - Right triangle with legs = 7, depth = 3
• Pyramid – Base = 4 squares
• Cut-Off Pyramid – Base = 16 squares, top row = 4 squares
• Challenge: Cube 2 x 2 x 2 with pyramid on top
FINISH THAT TECHNICAL DRAWING
Draw your Duplo Masterpiece on the isometric view of your technical drawing
LET’S TRADE AGAIN
• Find someone new and trade again
• Build their structure
• Was one drawing type easier than the other?
