When viewpoints collide, conflict arises. Can your pupils identify the components of conflict? The fourth in a series of 15 lessons about peacebuilding helps participants identify the underlying causes of conflict. Teams role play to...

Investigate the relationship between independent and dependent variables. Individuals begin by identifying independent and dependent variables from different problem situations. Then, using specific guidelines, they create posters...

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...

Evaluate young mathematicians' understanding of area and perimeter with this series of three assessment tasks. Challenging students to not only calculate the area and perimeter of irregular shapes, but to explain in writing their...

First graders read two stories.  In this literary elements lesson, 1st graders read The Hat by Jan Brett, notice patterns of prediction, identify the setting, problem and solution and compare the story to the book The Mitten.

In this solutions worksheet, students solve fifteen problems including finding molar concentrations, writing net ionic equations, determining molarity of solutions, identifying oxidized and reduced agents and finding mass percent of...

One thing that puzzles a lot of young algebrists is the factors in a word problem that are taken as "understood". This presentation on solving systems of linear inequalities does a great job walking the learner through how to tease those...

Our young scientists have now specifically identified a problem, and this step helps them think of possible solutions. An outline, including guidelines, for brainstorming helps scholars stay on the right path. The resource includes...

Use a vocabulary chart to introduce math functions. The class defines a list of mathematical vocabulary terms on a worksheet, as well as completes equations and expressions. They examine word problems and practice transcribing them into...

The 26th part of a 28-part series requires pupils to determine whether the answer to a problem requires surface area or volume. The class works problems about fish tanks that prompt individuals to decide, based on the question, which...

Now you'll never have trouble cutting a cake evenly again. Here is a set of five problems all about partitioning shapes into a given number of pieces and identifying the fractional amount of each piece. As learners progress through the...

Designed for teachers, this resource identifies problems learners face when attempting a research project and approaches instructors can use to help their class members overcome these obstacles. Suggestions are included for how to help...

Young scholars use problem-solving approaches to investigate mathematical content. They formulate problems from situations within and outside mathematics content. They warm up with a survey done by the teacher. Everyone uses practice...

Students participate in a service project about improving air quality. In this air quality lesson, students understand the problems and solutions for improvement of air quality issues. Students discuss and choose an air quality service...

Discuss the life of Franklin D. Roosevelt. This story, called "Franklin D. Roosevelt" by Laura Hamilton Waxman, is used to explore comprehension skills. Some of these skills include identifying prefixes and suffixes, making comparisons,...
