MCC2.NBT.2
Count within 1000; skip-count by 5s, 10s, and 100s.
MCC2.MD.1
Measure the length of an object by selecting and using appropriate tools such as rulers, yardsticks, meter sticks, and measuring tapes.
MCC2.MD.3
Estimate lengths using units of inches, feet, centimeters, and meters.

Draw a picture graph and a bar graph (with single-unit scale) to represent a data set with up to four categories. Solve simple put-together, take-apart, and compare problems10 using information presented in a bar graph.













5. Procedures
1st Activity: Build a Robot that Helps a Post Officer Carry Heavy Items.
1) Read the following story.
- A post officer cannot push heavy items because his back is badly injured.  Please build a robot to help the post officer push heavy boxes (wooden blocks).

2) Make a prediction. 
- Which of these sensors will you choose? Circle the answer among light sensor and distance sensor
- Which of these actors will your robot need? How many? Circle the number.

3)  Build a robot to solve the problem and record the results. 
- Build and experiment with your Cubelets robot to see if it works.
- What Cubelets did you use to make your robot?
- Which sensor did you actually use? Why?
- Which actors did you actually use? How many? Why?
- How many wood blocks can your robot push? 

2nd Activity: Build a Robot that Protects Animals on the Road at Night.
1) Read the following story.
- Animals that live in areas where people live tend to cross the road at night and, unfortunately, many of them get hit by cars. Please build a robot that can warn animals that a car is near by detecting a car’s headlights.

2) Make a prediction. 
- Which of these sensors will you choose? Circle the answer among light sensor and distance sensor
- Which of these actors will your robot need? How many? Circle the number.

3) Build a robot to solve the problem and record your results. 
- Build and experiment with your Cubelets robot to see if it works.
- What Cubelets did you use to make your robot?
- Which sensor did you actually use? Why?
Which actors did you actually use? How many? Why?

6. Review
- How does your robot work?
- What kinds of tasks that your robot can do?
