Number and Algebra: Again and Again

Building on knowledge from the previous lesson, the second lesson in this unit teaches scholars to identify and interpret rate of change and initial value of a linear function in context. They investigate how slope expresses the...

Do your learners like dinosaurs and theme parks? An ambitious activity invites learners to put together a plan for supplying dinosaurs for a new theme park. Pupils work together in groups to come up with their plan, which must include a...

Context is the key to understanding slope. A real-world application of slope uses a weight loss scenario with a constant rate of change to introduce the concept of slope of a line, before it makes a connection to the ordered pairs...

Learners investigate average rates of change for linear functions and connect the concept to slope. They then determine average rates of change in quadratic and exponential functions.

In this math and geography real world investigation, 6th graders plan a driving trip to a city that is located several states away from their home while recording the elevations of three cities that are included in the trip. They use...

Learners construct a variety of right triangles using a right-angled set square, cutting corners from pieces of paper or cardboard, and using dynamic geometry software. They measure the sides of these various right triangles and record...

In this money and coins worksheet, students participate in playing a money game that incorporates the process of making change. Students play the money game with a deck of seventy-five cards that have piggy banks with...

Watch your pupils Excel at using spreadsheets to graph data by watching a video that covers how to graph data in a scatter plot using Microsoft Excel. The video also covers how to change titles, scales, and labels, as well as how to...

What a scam! Middle and high schoolers pose as journalists exposing consumer fraud. In this lesson, they write an article for a magazine using data collected during previous investigations (prior lessons) to defend their findings that a...

Drink in this resource. Young problem solvers investigate a different way of looking at the problem of filling four liters of water from a three-liter cylinder and a five-liter cylinder. Isometric grids help with this understanding.
