HW: Complete WS Pe^(rt) and the half-life and complete any missing work.
Students in 4th hour went over the test prep 7-2 and turned it in. All students worked on the quiz on exponential functions. After the quiz was completed, they worked on a review worksheet of the 2 special formulas: A = Pe^(rt) and the half-life formula.
HW: Complete WS Pe^(rt) and the half-life and complete any missing work.

Students played a quick Kahoot game that reviewed key features of exponential functions: y-intercept, growth/decay factor and the corresponding rate.
We discussed what happens to y = (1 + 1/x)^x as the values of x get larger and larger. We did calculations using the TI-Nspire. We were able to relate to the definition of e as the limit as x goes to inifinity of (1 + 1/x)^x. This value is used as the base in the continuously compounded interest formula, A(t) = Pe^(rt). We did a couple of example together and showed where to find the e button on the calculator. Then students had time to work on WS 7.2 Test Prep & the other side, Viral Videos. HW: Complete WS 7.2 Test Prep & the other side, Viral Videos. Quiz on Exponential Function is tomorrow, 3/8. We went over Test Prep 7.1 & the other side, then collected it. Students watched a short video from Bill Nye on what is a half-life. Discussed the parts of the formula and then complete the carbon-14 example together. Students used the DE Techbook Section 2.2 Investigation 1 for the interactive equation writing tool. I demonstrated how to use the interactive feature and asked students to complete 3 correctly and then move onto the DE Worksheet.

We also went over WS 7.1 and turned it in. Students had the last 10 - 15 minutes to work on WS 7-1 (form G)/Test Prep 7-1. Students turned in homework from the past 2 assignments.
