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 game is awesome because it is presented to the students as though it is a fair game, but as they complete the experiment, they realize that it is actually not a fair game! Check out the preview! The kids can't tell initially but the game is skewed in favor of one team! Fill out the "difference chart" and you'll see why!

This assessment asks students to apply exponential functions to a real-world, relevant scenario! In addition to doing math, it will make them think about the impact of their words and of social media! Students will understand that spreading rumors can occur exponentially. Students are given a scenario about the spread of a rumor (each person tells ten people, who tell ten people, etc). They fill out a table, answer questions, and create the equation. Then they are asked to describe how it appl

Students are asked to use provided photos OR to find photos or works of art of their choosing to identify basic geometric concepts (like lines, planes, line segments, parallel lines, perpendicular lines, rays, etc). This gives students the opportunity to apply understanding of geometric concepts and to identify them in real world examples or artistic examples. This asks students to use proper geometric notation for naming concepts (naming angles correctly, etc.) DETAILED RUBRIC included!! (

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

Students are given real-world scenarios with problems to solve and questions to answer, and they must come up with a solution (which will necessarily involve square roots, squaring, and pythagorean theorem) and describe the process! In one problem students are given the area of a yard which is a perfect square. They must find the necessary amount of fencing (will have to take the square root to find the sides) and account for a gate. In the other problem, students are given the area of a bas

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 activity lists and gives visual aids of various quadrilaterals and their unique properties. Students are then asked questions like "How is a parallelogram different from a trapezoid?" Students must understand the various properties and what distinguishes one quadrilateral from another.

This project asks students to apply knowledge of polygons by identifying examples of them in business logos. We all know there's a huge push in Common Core for real-world, relevancy, and application. This project allows students to demonstrate mastery of comprehension over various polygons because in order to find them on their own they must be able to define them and differentiate between them!

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

Printable classroom poster--no more "I don't know!" Give students language to express their confusion and to get the clarification they need!
