Decimals
Are there any numbers between one and two?
Are there any prices between USD 1 and USD 2? There are things that cost one dollar fifty!
Have you noticed that the price of things at the supermarket which cost one dollar fifty is written as 1.50?
The zero matters
Be careful about the difference between 1.50 and 1.05. The first one means one dollar fifty while the second one – one dollar five cents (which is far less).
"One point nine, one point ten"
Sometimes students make a mistake when increasing the values they are looking for.
Decimals are counted in the following way
- 1 (one)
- 1.1 (one point one)
- 1.2 (one point two)
- 1.3 (one point three)
- 1.4 (one point four)
- 1.5 (one point five)
- 1.6 (one point six)
- 1.7 (one point seven)
- 1.8 (one point eight)
- 1.9 (one point nine)
-
1.10 (one point ten)NO! 1.10 is the same as 1.1 and 1.1000. The next value after 1.9 is 2.

Instructors Remote Training
If you are working with students and you want to introduce Robotics to your class or you want to mentor a FLL team, but you are insecure about your technical knowledge in the Robotics field, then this is the right place for you. Having in mind teachers' busy schedule, we have design two different schedules and added an option to design one just for you. FLLCasts's Mindstorms EV3 Robotics Online Training is the perfect match for any teacher.
After the completion of each task the participant has to upload his solution for verification.

Robotics with LEGO - Level 1.0 - Adventure in Space
The first level of the Robotics with LEGO curriculum for students in fifth to twelfth grades.
Various constructions with robots are built. Learn how to control the motors so that the robot navigates around the Moon and Earth in various ways. Getting to know the first two sensors. The robot can feel its surroundings with the help of the Touch sensor and avoid obstacles.
The Ultrasonic distance sensor can help the robot avoid obstacles. Students work with concepts like loop, degrees and medium motor. Robots can now do two different actions at the same time - while solving missions on a field, the third motor clears detected obstacles.

Lesson 3 - Clearing the landing zone
Intro
Today we are building a robot, what would automatically clear the landing site.
Before a space craft lands on the moon, you send a robot to clear the landing site. Your robot has landed on the Moon and its task is to clear the site and to prepare it for the landing of the bigger space ship.
The robot lands slightly further away from the site and it must find its way to it. Regretably it road is blocked by rocks that can not be moved. The robot must go around them.
