A Follow-up Exercise to Drawing Digital Numbers using Pro-Bot

The following set of questions is a follow-up to drawing digital numbers using Pro-Bot. Rather than draw every number from 0 through 9, these questions allow the students to draw just a sub-set of the numbers. This is how I plan to use it with my students: Write out one or two of the following questions each on chits and let the kids pick the chits randomly. This way, everyone gets to work on a different problem and it allows for a bit of math practice as well.

1. Use Pro-Bot to draw the odd numbers from 0 to 9 according to the dimensions given in the figure.
2. Use Pro-Bot to draw the even numbers from 0 to 9 according to the dimensions given in the figure.
3. Use Pro-Bot to draw the missing number in the following pattern: 0, 3, ___ , 9, 12
4. Use Pro-Bot to draw the missing numbers in the following pattern: 13, 11, ___ , 7, ___, 3
5. Use Pro-Bot to draw the numbers that are multiples of 3 in the group 0 to 9.
6. Use Pro-Bot to draw the numbers that are divisors of 8 in the group 0 to 9.
7. Use Pro-Bot to draw the number that you get as the result of the problem 2 x 2 x 2 = ?
8. The sum of 2 numbers is 5. One of the numbers is one more than the other. Use Pro-Bot to draw the two numbers according to the dimensions given.
9. The difference between two numbers is 3. The sum of the two numbers is same as 5 x 3. Can you identify the numbers? Draw the numbers using Pro-Bot according to the dimensions given below.
10. If your birthday is a single digit number, draw it using Pro-Bot with the dimensions given below. Else, add up the digits in your birthday and draw that number using Pro-Bot.
11. Use Pro-Bot to draw the prime numbers in the group 0 to 9. A prime number is a number greater than 1, that can be divided only by 1 and the number itself. It does not have any other divisors.

All measurements in the figure below are in centimeters.

Here is a set of programs for drawing the various numbers.
