Food mixed with math! Mmmm hmmmm! Students enter a scenario in which they and a friend are ordering a pizza and have three options: two round pizzas with different radii, and a rectangular pizza. One pizza-eater wants the most crust; the other just wants the biggest pizza! Students must apply the formulas for area (for rectangles and circles), perimeter, and circumference to make a choice about who would order which pizza! They will demonstrate understanding of which part of the pizza is repr

This document includes two different scenarios that can be modeled and solved with systems of linear equations. 1) Students are given pricing info for two different car rental companies and must: write the linear equations make tables for each equation graph them analyze what the solution (the point of intersection) represents answer questions like "which company is cheaper if you're driving 18 miles?" 2) Students are given information about the price of child and adult tickets for a puppet sho

Students are given the pricing for two different T-shirt companies, asked to write linear equations for each company, and then to set them up as a system of equations. After writing the equations, there is a table created that they must fill in and a grid provided on which to graph the equations. They must then analyze the information by answering questions like "Which company would you order from if you ordered 5 t-shirts? What about 15? What about 20?" so that students may analyze the point o

Geometry which incorporates food!!! (You don't actually have to use real sandwiches) Students must use a triangle congruence theorem (either side-side-side, side-angle-side, angle-side-angle, angle-angle-side, or hypotenuse leg) to prove that when you cut a sandwich in half diagonally, the two resulting triangles are congruent and also that when you cut it into quarters, all four triangles are congruent! Examples included for students so they can see what to do! Make sure you download the pre

This asks students to consider sets of data for three different train companies and to decide which train will get them to their destination (a Pacific Cruise!) the quickest, but also which train company is most reliable. That is, students will see that one train company travels more quickly on average (mean), but the range is very wide, making them unreliable. Another train company has a slightly longer average travel time, but has a small range, indicating reliability! Students must calculate
