Equivalent ratios show up on tape. Young mathematicians use tape diagrams to create equivalent ratios in the initial lesson on the topic. They learn the definition of equivalent ratios and use it to build others in the third segment of a...

Decide which concentration of mixtures is the strongest. Pupils use tables to compare ratios involved in mixtures. They use two methods to make the comparisons — by finding equivalent values within the tables or by comparing the...

From minimum wage to minimizing injuries, young workers need to know their rights! The sixth and final lesson in a series of college and career readiness activities gets eighth graders thinking about safety and labor laws. 

How fast is your class? Learners determine the amount of time it takes individuals to walk a given distance and calculate their speeds. Pupils solve distance, rate, and time problems using the formula and pay attention to the...

Ratios may not be created equal, but they are equivalent. Pupils learn the theorem relating equivalent ratios and equal values in the eighth segment in a series of 29. Classmates use the theorem to determine whether ratios within...

You know 4 + 4 + 4 = 3(4), but what about x + x + x? Pairs work together to develop equivalent expressions relating multiplication and addition in the third lesson of a 36-part series. They extend their knowledge of multiplication as...

Students investigate about acids, bases, and pH and relate this information to the problem of acid deposition. They use pH paper, students test common household substances to determine whether they are acidic, basic, or neutral. Pupils...

Young scholars apply knowledge of soil, environmental impacts, economics, multiple human demands, and use given data for a proposed scenario in making land use decisions. They debate land use issues and/or scenarios and discuss a case...

Talk with your pupils about the importance of staying focused at the grocery store. Your special education class will discuss how to create and use a shopping list. They will make a shopping list and pretend to use it in a role-play...

Learning to cook, follow directions, and presenting information are skills every body needs to know. Learners complete a recipe-in-a-jar activity to hone these life skills. They follow the directions, choose and use correct measurement...

The game should be fair at all costs. The mini-assessment revolves around the ability to use probabilities to determine whether a game is fair. Individuals determine compound events to calculate simple probabilities and make...

Build tables by understanding their structure. Scholars take a closer look at the structure of ratio tables in the 10th segment in a 29-part series. Individuals realize that the tables can be built using an additive or...

Find a way to work with rates. The 23rd part in a 29-part series presents work problems for the class to solve given work rates. Pupils compare rates to determine which is faster. Some problems require learners to convert the rates to...

Continuing from the previous lesson in the series, scholars learn to use positive and negative integers to describe real-world situations. In groups, they come up with their own situations for given positive and negative integers. 

Scholars apply the concepts of box plots and dot plots to summarize and describe data distributions. They use the data displays to compare sets of data and determine numerical summaries. 

Inequalities: when one solution just doesn't suffice. Individuals learn to write inequalities in real-world contexts and graph solution sets on the number line. All inequalities in the lesson are of the form x < c or x < c.

The Universal Declaration of Human Rights passed in 1948 when the majority of members of the United Nations voted in favor of the resolution. Scholars use their knowledge of human rights to determine ways they personally can help promote...

Young learners research and present information about a chosen subject to their peers, parents, instructors, and community. This instructional activity has a strong research and public speaking component, and would be ideal for your...

Students recognize dependent and independent variables in an experiment by practicing manipulation of variables; students practice designing experiments that contain the two types of variables.

Sixth graders discover the problems that early Mesototamian farmers faced while developing agriculture in the land between the Tigris and Euphrates Rivers. They design a working model that solves those unique challenges.

Collaborative groups connect resistors and solar panels in series and measure electrical resistance, voltage, and current. The objective is to order 16 solar panels from strongest to weakest. They graph current-voltage and power curves...

Students explore the world of work and the opportunities that exist in today's world. They identify specific careers and colleges that match their interests and abilities and investigate various corporations and businesses that employ...

Inject fun into your math review! Pupils review basic math operations with decimals as well as addition and subtraction with simple fractions. In this number operations lesson, students work in groups to create a game for the math skill...

Young scholars examine how to locate and access data sets.  In this climate change lesson students import data into Excel and graph it.
