This is a rectangle subdivision task; ideally instead of counting each square. students should break the letters into rectangles, multiply to find the areas, and add up the areas. However, students should not be discouraged from using individual counting to start if they are stuck. Often students will get tired of counting and devise the shortcut method themselves.

This short video and interactive assessment activity is designed to teach third graders an overview of area and perimeter.

Students will identify which unit of measure inch, foot or yard) is best for measuring various items in the outdoor garden. They will then apply the use of the appropriate tool to measure a variety of objects to the nearest marker.

A fourth function of money is that anytime you take on a debt, when the time comes to repay it, you can use money. This is highly related to the idea of "legal tender", which you can also learn about in this video. Created by Grant Sanderson.

Students are introduced to the technology of flexible circuits, some applications and the photolithography fabrication process. They are challenged to determine if the fabrication process results in a change in the circuit dimensions since, as circuits get smaller and smaller (nano-circuits), this could become very problematic. The lesson prepares students to conduct the associated activity in which they perform statistical analysis (using Excel® and GeoGebra) to determine if the circuit dimension sizes before and after fabrication are in fact statistically different. A PowerPoint® presentation and post-quiz are provided. This lesson and its associated activity are suitable for use during the last six weeks of the AP Statistics course; see the topics and timing note for details.

Students learn that math is important in navigation and engineering. They learn about triangles and how they can help determine distances. Ancient land and sea navigators started with the most basic of navigation equations (speed x time = distance). Today, navigational satellites use equations that take into account the relative effects of space and time. However, even these high-tech wonders cannot be built without pure and simple math concepts — basic geometry and trigonometry — that have been used for thousands of years.

Students will use their knowledge of stem and leaf plots to represent temperature in various locations outdoors.

This short video and interactive assessment activity is designed to teach fourth graders about multi-step subtraction of weights with compound units (metric units) - word problems.

This short video and interactive assessment activity is designed to teach fourth graders about subtracting compound units in years and months.

This short video and interactive assessment activity is designed to give fourth graders an overview of conversion between units of weight (english units).

This short video and interactive assessment activity is designed to teach fourth graders about finding the different weight from tables (metric units).

This short video and interactive assessment activity is designed to teach fourth graders about subtracting capacities in compound units (english units).

This short video and interactive assessment activity is designed to teach fifth graders about subtracting capacities in compound units (english units).

This short video and interactive assessment activity is designed to teach fifth graders about subtraction in grams.

This short video and interactive assessment activity is designed to teach fifth graders about subtraction in kilograms.

The seventh episode of our podcast series discusses the supply side of the market – the law of supply, slope of the curve and the difference between a change in supply and a change in quantity supplied.

This learning video presents an introduction to graph theory through two fun, puzzle-like problems: ''The Seven Bridges of Konigsberg'' and ''The Chinese Postman Problem''. Any high school student in a college-preparatory math class should be able to participate in this lesson. Materials needed include: pen and paper for the students; if possible, printed-out copies of the graphs and image that are used in the module; and a blackboard or equivalent. During this video lesson, students will learn graph theory by finding a route through a city/town/village without crossing the same path twice. They will also learn to determine the length of the shortest route that covers all the roads in a city/town/village. To achieve these two learning objectives, they will use nodes and arcs to create a graph and represent a real problem.

Course description:

Metrics and measurement are important strategic tools for understanding the world around us. To take advantage of the possibilities they offer, however, one needs the ability to gather, work with, and analyse datasets, both big and small. This is why metrics and measurement feature in the seminar course Technology and Evolving Forms of Publishing, and why data analysis was a project option for the Technology Project course in Simon Fraser University’s Master of Publishing Program.

The assignment:

“Data Analysis with Google Refine and APIs": Pick a dataset and an API of your choice (Twitter, VPL, Biblioshare, CrossRef, etc.) and combine them using Google Refine. Clean and manipulate your data for analysis. The complexity/messiness of your data will be taken into account”.

Students strengthen their communicate skills about measurements by learning the meaning of base units and derived units, including speed one of the most common derived units (distance/time). Working in groups, students measure the time for LEGO MINDSTORMS(TM) NXT robots to move a certain distance. The robots are started and stopped via touch sensors and programmed to display the distance traveled. Using their collected data, students complete a worksheet to calculate the robots' (mean/average) speeds at given motor powers.

This short video and interactive assessment activity is designed to teach fourth graders about total length in compound units (english units).
