The Flippy Do Pro is still using 8 bits to represent a number.When using the Flippy Do Pro, the numbers on the left-hand side of the line are whole numbers and those on the right-hand side of the line are fractional numbers.But this time, the Flippy Do Pro is already filled with binary place values assigned in a different way - they include fractions. The Flippy Do Pro is similar to the one you made before.Fill out all the numbers if they are not already done. Provide each group with a copy of the Flippy Do Pro Template and scissors.ĭo This: Cut and fold your Flippy Do Pro following the guidance on the slide. What happens when there aren't enough place values to represent a number? You will explore this with a new version of the Flippy Do, the Flippy Do Pro! Now that you have started thinking about place value and overflow, we are going to work on a different problem.

What about when the odometer reaches the max value? What happens if we keep driving? Flippy Do Pro The number in the odometer keeps going up as we drive. They will consider an odometer to explore what happens when you add one to the largest number you can represent in a number system. Students will tackle the problem of "running out of place values" when counting to bigger and bigger numbers. You also can't give someone $1.25 in change (because you have no nickels!)Īt both extremes of the number range, large and small - and in between numbers - you are unable to build some numbers because you don't have the place values to do so.

The least change you can give is $0.10.

The largest amount of change you can give someone is $99.90.

This can happen when you try to store very large numbers, very small ones, and everything in-between! The goal of the prompt is to understand the very real problem of making sure that enough place values are available to represent numbers.

What would you do if someone needed 7 cents in change?ĭiscussion Goal: Today we're going to explore what happens when you don't have the right "places" to store information.

What's the largest amount of change that you can give someone?.

In the register all you have are nine $10 bills, nine $1 bills, and nine dimes. brfĭiscuss: Imagine you work at a local store.

Flippy Do Pro worksheet in braille, Duxbury file.

When written in binary, these values are 1, 10, 100, 1000, 10000, and so on, and so are the incremental place values in this binary number system. When using this binary representation of numbers, certain values (1, 2, 4, 8, 16, etc.) are seen repeatedly. They learn that, while a number system is infinite, the physical representation of numbers requires place values - which are finite, and limit the ability to represent numbers.

Students discover the limitations of creating numbers that are "too big" or "too small" to count. This lesson introduces students to the practical aspects of using a binary system to represent numbers in a computing device. Understand that overflow and roundoff errors result from real-world limitations in representing place value.

Describe how to include fractions in the binary number system.

They make a "flippy do pro" to practice binary-to-decimal number conversions which include fractional place values.

Students extend their understanding of the binary number system by exploring errors that result from overflow and rounding.
