Big Idea 3: BIG IDEA 3Archived

A variety of graph paper types for printing, including Cartesian, polar, engineering, isometric, logarithmic, hexagonal, probability, and Smith chart.

Type: Educational Software / Tool

Students learn how to calculate average speed and how to construct and interpret a distance vs time graph.

Type: Lesson Plan

ResourceID: 39599

This lesson will allow students to investigate the location of earthquakes and volcanoes throughout the world and determine how they relate to the tectonic plates.

Type: Lesson Plan

The students will complete an inquiry activity using dominoes to determine what variables affect the speed of the chain reaction. Students will have to consider and decide on the best spacing between dominoes to achieve the fastest travel time and ensure the spacing remains constant by carefully measuring the distance between each domino. They will set up 5 dominoes at a time to set off a chain reaction alongside another 5 dominoes space differently. Students can create a bar graph to show how the spacing affects the speed. Students can have fun while learning or reinforcing their understanding of potential and kinetic energy, measuring distance, measuring elapsed time, recording data, making and interpreting graphs and using the distance formula to calculate the rate of speed.

Type: Lesson Plan

This lesson is designed to help students decode word phrases and then translate them from word form into numerical form. It provides a resource, in the form of a foldable, that can be kept all year and used anytime the students need to decode word phrases.

Type: Lesson Plan

Introductory lesson on the distributive property using word problems as context for area models.

Type: Lesson Plan

Students design an experiment to model a leaky faucet and determine the amount of water wasted due to the leak. Using the data they gather in a table, students graph and write an equation for a line of best fit. Students then use their derived equation to make predictions about the amount of water that would be wasted from one leak over a long period of time or the amount wasted by several leaks during a specific time period.

Type: Problem-Solving Task

There are lots of ways to receive income, and lots of ways to spend it. In this EconomicsMinute teaching idea, students will develop two budgets, or plans, to help them decide how to allocate their income.

Type: Teaching Idea

Students will solve density problems.

Type: Teaching Idea

These activities give students opportunities to investigate weather conditions that involve reading and recording temperatures, graphing, making charts, solving word problems, and working with numbers.

Type: Teaching Idea

This video models solving equations in one variable with variables on both sides of the equal sign.

Type: Tutorial

This Khan Academy presentation models solving two-step equations with one variable.

Type: Tutorial

Introduction to solving one variable multiplication equations of the form px = q.

Type: Tutorial

This lesson unit helps teachers assess how students perform arithmetic operations, write and evaluate numerical expression s from diagrammatic representations, apply the distributive and commutative properties, and find areas of compound rectangles. The time for the lesson is broken into a 15 minute pre-lesson task, an 80 minute lesson (or two 40 minute lessons), and a 15 minute follow up lesson or homework. Individual students will need a copy of the two tasks, a mini-whiteboard, a pen, and an eraser. Each small group will need cut-up copies of the card sets, a large sheet of poster-sized paper, and a glue stick.

Type: Unit/Lesson Sequence

This Khan Academy video tutorial introduces averages and algebra problems involving averages.

Type: Video/Audio/Animation

This resource provides linear functions in standard form and asks the user to graph it using intercepts on an interactive graph below the problem. Immediate feedback is provided, and for incorrect responses, each step of the solution is thoroughly modeled.
