Get Squared Away

As math teachers, we frequently get the question "when will I use this?". With this project, students are able to explore one very practical, real-life application of using area, surface area, and volume calculations. In this four phased project, students will start by researching and designing their own raised garden beds. The four different phases of the project ask students to explore types and cost of wood for building the garden beds, material pricing and volumes for both a sub-irrigation s

The combinations and permutations guided notes and worksheet walk students through the key parts of Combinatorics (counting) in Geometry. The notes start with the Fundamental Counting Principal (which likely was talked about during probability) and introduces the concepts of factorials, permutations, and combinations. Practice examples are built into the notes over combinations and permutations. The third page is a worksheet over combinations and permutations. Two answer keys are provided: one w

The Probability of Independent and Dependent Events worksheet asks questions about whether two events are independent versus dependent and has students calculate probabilities of both independent and dependent events. This worksheet was made for a high school geometry level course but could also be used for introducing probability in statistics or an honors middle school level course. This one-page worksheet would work well as a formative assessment after notes or as a homework page. The workshe

The Points of Concurrency in Triangles guided notes and practice introduce the concepts of orthocenter, circumcenter, incenter, and centroid in triangles. The notes include an example after each triangle relationship to help students gain practice with solving for missing values using the circumcenter, incenter, or centroid of a triangle. The scaffolded notes provide an extra opportunity to keep students engaged and provide them with valuable foundations for the concepts we will discuss in Geome

The Leaning Tower of Pisa is famous for it's tilt. The question is: how close is the tower to falling? This investigation takes students through answering this question. This uses a Geogebra applet I created (a website link is provided) so students will need access to a computer per student or group of students. This activity allows students to compare the ratio of height over base at different angle measures to estimate the angle the tower is currently leaning. This ratio is our tangent ratio a

The Two-Way Tables Probability worksheet asks students to calculate different probabilities using two-way tables. This worksheet was made for a high school geometry level course but could also be used for introducing probability in statistics or an honors middle school level course. This one-page worksheet would work well as a formative assessment after notes or as a homework page. The worksheet comes with an answer key (including all work shown). This worksheet could work well on its own or pai

The Introduction to Probability and Sample Spaces worksheet asks questions about basic probability and sample spaces. This worksheet was made for a high school geometry level course but could be also used for introducing probability in statistics or an honors middle school level course. This two-page worksheet would work well as a formative assessment after notes or as a homework page. The worksheet comes with an answer key (including work shown). This worksheet could work well on its own or pa

The ratios and proportions guided notes and examples included are set up in such a way that they can be used as doodle notes for your students. The similarity scaffolded notes provide an extra opportunity to keep students engaged and provide them with valuable connections between different concepts in Geometry. Key vocabulary and practice examples are included in the single page of notes. The second page of the document is a worksheet for students to complete over ratios and proportions. The not

The scale models and drawings guided notes and examples included are set up in such a way that they can be used as doodle notes for your students. The scaffolded notes provide an extra opportunity to keep students engaged and provide them with valuable connections between different concepts in Geometry. This lesson is a great practical application of similarity and scale factors. Key vocabulary (such as scale model and scale factor) and practice examples are included in the single page of notes.
