We're preparing for our Interim Assessment for the Fall Semester this month.

Here is some information about your Interim Assessment, including extra practice problems and suggestions for more problems that you can use to practice.

Math Interim Assessment is second one on Friday, 1/17.

All short answer IB problems, cumulative from start of this school year. You should bring your GDC, or ask for one ahead of time. If you ask for a GDC the day of the exam, you'll receive a 5% penalty on the exam. You'll have access to the formula book. Expect a full two hour exam, about 80-100 marks:

• arithmetic/geometric sequences/series
• financial math (compound interest, inflation, loans, annuities, TVM solver, etc.)
• straight lines and their graphs (parallel/perpendicular lines, slope-intercept form, point-slope form, standard form, etc.)
• Voronoi diagrams (constructing them, adding a site, finding missing edges/sites/verties, interpreting them, nearest neighbor interpolation, largest emtpy circle, etc.)
• Functions and the modelling cycle (linear, piecewise linear, quadratic, cubic, variation, GDC skills, etc.)

Thursday, 1/2 - we got back our functions and modelling exams and we went over them.

Friday, 1/3 - Thursday, 1/9 - we are doing Expos to help us prepare for our Interim Assessment. Here are the slides explaining the procedure for Expos and listing your group assignments. Here are the eight Expo problems covering most of the topics we've learned this semester so far. Here is the TBLS Expo rubric again for your reference. We are prepping in class on Friday and Monday. Your homework for the weekend is to continue prepping. We are presenting on Tuesday, Wednesday, and Thursday.
