In this unit we will focus on the basics of real numbers and the different ways they can be represented. We will dive into significant figures, scientific notation, percent error, and laws of exponents and logs.
You will have 5 lessons to complete this unit. Please look at the due dates to make sure you are on pace.
For this lesson, you will need to watch the mini lesson and complete the guided notes (page 1 only) as you watch. Remember you can pause, rewind, and rewatch as much as needed. Once you are done complete the practice problems or activity in class.
Para esta lección, tendrá que ver la mini lección y completar las notas guiadas (sólo en la página 1) mientras la ve. Recuerde que puede hacer una pausa, rebobinar y volver a ver tanto como sea necesario. Una vez que haya terminado, complete los problemas de práctica o la actividad en clase.
In this lesson, you will learn how to round correctly to the number of sig figs needed. In IB, if an answer needs to be rounded, then the number must be rounded to 3 sig figs. If not rounded correctly, the answer is considered wrong and you will lose a mark. Watch the following mini lesson and complete page 2 of the guided notes. When you finish with the notes, you can begin the practice activity.
You're ready for your first mastery check! Once complete, turn in and move on to the next lesson.

You are doing research in a biophysics lab where you need to calculate the energy of various photons. If a particular type of light has a wavelength of 6430 Å, what is the energy of the light photon in Joules?
Formula E= hc/𝜆 where:
E= Energy of the photon (in Joules),
𝜆= wavelength of the light,
c= speed of light (300000000)
h= Planck's constant 0.0000000000000000000000000000000006626176
Try converting speed of light and Planck's constant into scientific notation into scientific notation. Now solve for Energy.
This video will cover how to do the first 3 problems on page 8 (see right)
You're ready for your mastery check! Once complete, turn in and move on to the next lesson.
When you complete these questions, pick your own numbers.
x, a, and b should be a number over 1000
p and q should be a number between 1 and 10 thats a decimal Example: 3.81
Percent error is a way that we can measure how precise our answers are. Make sure you locate your formula in your IB formula booklet.
This lesson is review based. You learned all about laws of exponents and laws of logarithms in Algebra 2. there is a foldable you need to complete and put on page 11 of your notebook. Of you need extra review and practice there is a Delta Math assignment that you can complete for merits. This lesson has no video. Just the foldable and delta math as review.
Try to complete the foldable with looking at the answer key first. See how much you remember from last year!
In this lesson we will learn how to convert between logarithmic form and exponential form. You may need to use the laws from the previous lesson to simply and condense your expression first and then convert into the opposite form in order to solve.
