This resource from the National Library of Virtual Manipulatives shows students how to rename fractions to have a common denominator and then add them. It is appealing because it visually engages the students by showing them what happens to a unit (a rectangle is used here) as the denominator increases or decreases. As the denominator increases or decreases, the partitions are shown accordingly, and the effect on the numerator is shown as well. This is a convenient, visual way to show students how to manipulate fractions for adding.

In this activity, students construct adding slide rules, scaled with linear calibrations like ordinary rulers. Students learn to move these scales relative to each other in ways that add and subtract distances, thus calculating sums and differences. This is Activity A1 in the "Far Out Math" educator's guide. Lessons within the guide include activities in which students measure, compare quantities as orders of magnitude, use scientific notation, and develop an understanding of exponents and logarithms using examples from NASA's GLAST mission. These are skills needed to understand the very large and very small quantities characteristic of astronomical observations. Note: In 2008, the GLAST mission was renamed Fermi, for the physicist Enrico Fermi.

In this video, we explore some concepts fundamental to algebra. To streamline the discussion of relationships between physical quantities, we introduce variables, functions, composition, and inverse. By thinking about the concept of an inverse function, we obtain our first glimpse of the imaginary root (i.e. square-root of -1) and the complex plane.

This lesson examines rectangular shapes and the relationship between their areas and perimeters. The goal is to provide students with the ability to measure these features, understand that perimeter and area have a relationship, and recognize and apply their new knowledge in real-life applications. This lesson builds on previous lesson that the students have done on measurement of length and perimeter.

This is a lesson for learning about area and perimeter of rectangles. ...

This is a lesson for learning about area and perimeter of rectangles.

This corresponds to "College and Career Ready" standard (3.MD.7a) -- Find the area of a rectangle with whole-number side lengths by tiling it, and show that the area is the same as would be found by multiplying the side lengths. (I was not able to find that standard here.)

This is a hands-on guided lesson for relating area to factors. Students ...

This is a hands-on guided lesson for relating area to factors. Students will model area of rectangles using Cheez-Its and define factors as the dimensions of the rectangles.

Learners become introduced to the concept of budget and its use in business settings. They will prepare a simple budget in excel for two business trips from Washington D.C. to both a domestic and an international destination of their choice researching various websites and they will create a short presentation on ways to save money on business travel. The lesson will provide learners with an opportunity to develop basic literacy in MS office applications, basic financial literacy and to hone their internet researching skills.
