Discover how math is required for quality construction when a Master Carpenter shares his experience and expertise. This video focuses on explaining slope as rise over run and shows how slope comes into play when building homes to take...

This hands-on lesson discusses and explores rational numbers. Students construct personal fractional strip kits and use them to compare fractional amounts and investigate equivalence. The lesson plan includes instructions, materials, and...

In this task, students apply the definition of a parallelogram in the context of a geometric construction. Aligns with G-CO.C.11.

Suppose we are given a circle of radius r. The goal of this task is to construct an equilateral triangle whose three vertices lie on the circle. Aligns with G-CO.D.13.

In this task involving temperature conversions, students construct a linear function given two input-output pairs, investigate the inverse of a linear function, and reason about quantities and/or solving a linear equation. Aligns with...

The goal of this task is to construct the circumcenter of a triangle, that is, the point which is the same distance from each of the triangle's three vertices. This task shows that the three perpendicular bisectors of the sides of a...

Write equations in point-slope form given two pairs of values, and convert the equation into slope-intercept form. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

Practice finding the equation of a line passing through two points. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

This problem examines the growth of algal blooms in Chesapeake Bay. Students build an exponential function modeling algae concentration based on the information provided, and gain an appreciation for the exponential growth exhibited...

In this instructional activity, learners learn how to inscribe a square in a circle. Aligns with G-CO.D.13

In this task, young scholars inscribe a regular hexagon inside a circle and compare its area to that of the circle. Aligns with G-CO.D.13.

The goal of this task is to examine some population data for large cities from a modeling perspective. Students are asked to decide if the population data can be accurately modeled by a linear, quadratic, and/or exponential function, and...

The context of this task is that a quarter was put into a bank account in 1901 and learners are asked to calculate its value in 2013 at two different interest rates. Those amounts are compared to the appreciation rate of a rare and...

This task asks students to analyze a set of data about the height of a basketball for each time it bounces. They choose a model that reasonably fits the data and use the model to answer questions about the physical context. This second...

In this task, learners investigate the relationship between linear equations and linear functions. Aligns with F-LE.A.2.
