Moving Straight with RoboMath: 1 Discuss with your partner/table: Ziffle’s Tribot required 1.3 rotations to travel 25cm. How many rotations must Ziffle program in his Move Block duration for his Tribot to travel 75cm? Scale Factor 1.3 rotations 25 cm x rotations 75 cm = Scale Factor x = 1.3 rotation x 3 x = 3.9 rotations 75 cm 25 cm Scale Factor = = 3

Moving Straight with RoboMath: 2 Discuss with your partner/table: Ziffle’s Tribot required 520 degrees to travel 25cm. How many rotations must Ziffle program in his Move Block duration for his Tribot to travel 62.5cm? Scale Factor 520 degrees 25 cm x degrees 62.5 cm = Scale Factor x = 520 degrees x 2.5 x = 1,300 degrees 62.5 cm 25 cm Scale Factor = = 2.5

Moving Straight with RoboMath: 3 Discuss with your partner/table: Ziffle’s Tribot required 1.25 rotations to travel 25cm. How many rotations must Ziffle program in his Move Block duration for his Tribot to travel 108cm? Step 1: Write Ratio Step 2: Create Proportion Scale Factor 1.25 rotations 25 cm x rotations 108 cm = Step 4: Use Scale Factor Scale Factor Step 3: Calculate 108 cm 25 cm x = 1.25 rotations x 4.32 x = 5.4 rotations Scale Factor = = 4.32

Moving Straight with RoboMath: 4 Ziffle’s Tribot required 500 degrees to travel 25cm. How many degrees must Ziffle program in his Move Block duration for his Tribot to travel 94cm? Step 1: Write Ratio Step 2: Create Proportion Scale Factor 500 degrees 25 cm x degrees 94 cm = Step 4: Use Scale Factor Scale Factor Step 3: Calculate 94 cm 25 cm x = 500 degrees x 3.76 x = 1,880 degrees Scale Factor = = 3.76
