## Algebra 2 Explores Transformations in Graphing

Mrs. Sklarin’s Algebra 2 class utilized technology to explore transformations in graphing. The students used a TI-Nspire program to investigate how changing the coefficients and constants change the graph of a function. We were able to move the graphs around by changing one value at a time. The calculator did the heavy lifting and we got to see the immediate change appear The effect of that one change became apparent on all the different types of graphs. The students made connections between the location of each number and how the graph moved. (ex. y = a(x-h)^2 + k) Then we switched to student dry-erase boards and the students had to graph new functions using the transformations. We used most of the parent functions; y = x, y = x^2, y = x^3, y = square root (x), y = 1/x, and y = absolute value (x). To exit class each student had to write what each value did to change the graph.  The time flew by as we enjoyed the movement of the functions.on the screen.

## Statistics Classes Investigate the Length of a “Minute”

When you are having fun, time is said to “FLY.”  When you are waiting for something, time seams to slow down.  On Friday, Mrs. Sklarin’s Statistics classes tried to wait a minute to stop the clock.  Each student tried to time a minute three times. Some students were very reliable with their “minutes” while others were all over the place.  Many students showed bias by always being shorter, and a few were always longer. We had two very accurate students; our swimmer and dancer.  They are used to counting time. We enjoyed comparing our “minutes” and seeing who knows their time.

## Heritage Academy Competes at SCISA Math Meet

It was an early morning as the ten students from Heritage Academy boarded the bus to Sumter, SC for the 2015 SCISA High School Math Meet.  We fielded two teams this year having five students from the morning session and five students from the afternoon session. Sponsors Mrs. Sklarin and Mr. Bracken determined the two teams made up of students from both sessions. SCISA recognizes the member from each team with the highest score.  This year Will was recognized from Team 1 and Matais was recognized from Team 2. We are proud of them and all our students for their participation in this math competition. They represented Heritage Academy well.

## Economics Stock Market Game

Economics students emerged as the leaders of Mr. Ted Zawacki’s Stock Market Game. The game taught a realistic approach to daily investing with it unpredictability and volatility. Twenty-three students were actively and enthusiastically engaged. Charles Spencer-White managed the highest return on his investments. He was followed closely by Alexander Vegh, Will White and Kyung Hwan Chung.
