This 3-mod course, which places a strong emphasis on developing the student’s ability to construct, communicate, and justify mathematical arguments, consists of one mod of algebraic content and two mods of geometric content, covering the first third of a typical yearlong “honors” Algebra 2 course and the first two thirds of a typical yearlong “honors” geometry course (or about half of the topics in the IGCSE Extended curriculum not already covered in Math 1 and 2). In the algebra mod, the focus is on understanding the concept of a function in general, with particular attention to linear, quadratic, and exponential functions. The connections to sequences and series are explored. In the geometry mods, the focus is on formalizing a student’s existing geometric knowledge through the lens of mathematical proof.
Taken over the course of 9th and 10th grades, Math 3 and Math 4 prepare interested students to begin IB SL Mathematics: Analysis 11th grade. With the addition of the first two mods of precalculus in 10th or 11th grade, students are prepared to begin IB HL Mathematics: Applications in 11th grade.
Sophomores who have taken Math 2 in 9th grade typically take only the algebra mod of this course.
