Before recapping last week, I would like to give you details of the upcoming week's activities. Our final total for our bake sale and snow-cone fundraising was $288.60 which comes to $8 per person raised. Students were asked to bring in the remaining $12 on Monday. On Tuesday, we ask that all supplies are brought in. (Past experience has shown that it is best to take an inventory of our supplies BEFORE the day we leave!!) Students will begin Wednesday morning in the classroom where we will kick-off the Rate Our Beaches Project in the morning. We will be completing preliminary activities to enhance our experience at San Clemente. We will have lunch at school, pack our cars and leave immediately afterward(approximately 1:00 pm). We will return to school on Friday at noon. I have emailed all parents the full camp-out itinerary. If you have not received it, please contact me immediately at lisa@innovationsacademy.org .
To all who came to Back To School Night, I enjoyed meeting with you! It was wonderful sharing in your students' experiences in 8th grade so far. Please know that my classroom is open to you anytime, not just during family nights and school events! Please stop in often to see your child's work or to discuss their successes or challenges.

Common Core CA 8th Grade Math Standard - Geometry 8.G-1,2,4:
Understand congruence and similarity using physical models, transparencies, or geometry software.
1. Verify experimentally the properties of rotations, reflections, and translations
2. Understand that a two-dimensional figure is congruent to another if the second can be obtained from the first by a sequence of rotations, reflections, and translations; given two congruent figures, describe a sequence that exhibits the congruence between them.
4. Understand that a two-dimensional figure is similar to another if the second can be obtained from the first by a sequence of rotations, reflections, translations, and dilations;
given two similar two-dimensional figures, describe a sequence that exhibits the similarity between them.
given two similar two-dimensional figures, describe a sequence that exhibits the similarity between them.

In Math, our discussion and activities to explain real numbers is continuing. We discussed the difference between rational and irrational numbers as well as learned how to estimate square roots that are not perfect squares. Students are beginning to recognize square roots that are not perfect squares are irrational numbers.
For example:
Between what two whole numbers would you find the square root of 20?
Answer: Between 4 and 5.
Why? Because the square root of 16 = 4 and the square root of 25 = 5. Since the square root of 20 lies between the square root of 16 and the square root of 25, then it must also be between the whole numbers 4 and 5.
For more practice, check out http://www.khanacademy.org/math/algebra/exponents-radicals/e/square_roots_2 click on the hints for help.
So how is this going to help me in real life? Estimation is a valuable tool in measurement, grocery shopping, determining how long it will take to travel somewhere.... When we recognize that fractions, decimals, and irrational numbers are just numbers that fall between whole numbers, we can at least get a close estimation to a number that is easier to visualize.
We will begin working on integers this upcoming week.
