A seemingly simple question that reveals a lot about a student's understanding of fractions. In finding an answer, learners compare fractions with different denominators that are both greater and less than one. No number line is...

Here is another way to illustrate division of a whole number by a unit fraction. In this case, the problem is asking if there are so many servings per cup, how many servings are in a package of multiple cups. Learners are to model their...

Learners practice using their knowledge of how to interpret a function and use function notation. The activity includes two questions. Given an input of a function and its output, the first question asks learners to write the ordered...

With so much talent in the classroom, do your musicians and athletes have related interests? This problem has your learners taking data from their classmates to decide whether there is an association between the two activities. The...

Learners translate numbers, from real life scenarios of throwing a ball vertically upward, into a given formula so the remaining variable is the solution.

With minimal setup and maximum freedom, young geometers are encouraged to think outside the box on a seemingly simple application problem. Though the task seems simple, measuring a given paper clip and finding how many 10 meters can...

Math: The only subject where the solution to a problem is seven million matches. Young scholars first complete an assessment task estimating the number of matches they can make from a tree of given dimensions. They then evaluate provided...

Math language? Set notation is used in mathematics to communicate a process and that the same process can be represented as computer code. The concept to the loop in computer code models the approach pupils take when creating a solution...

Explore nonlinear systems through graphs and algebra. High schoolers begin by examining the different types of quadratic functions and their possible intersections. They then use algebraic methods to solve systems containing various...

Compare graphing an inequality in one variable on a number line to graphing an inequality in two variables on a coordinate plane. Young mathematicians work on a puzzle matching inequalities and their solutions. They then complete a...

Don't drop the ball on the resource ... drop an egg instead! A teacher-led demonstration has the class consider how to drop eggs into glasses when a tray is in the way. Hint: If you've ever seen a magician pull a tablecloth off a table,...

What happens when two parties can't come to agreement? Scholars explore the role of a mediator through part 10 of a 15-part series of peacebuilding lessons. Through individual work and role play, pupils brainstorm solutions until they...

Tackle a common misconception using a performance task. Dividing by a variable to eliminate a variable may seem like a good idea, but simplifying the variable eliminates solutions as well. Learners develop algebraic and graphical support...

Pupils explore the amount of water people use in agriculture and for personal use. They compare water usage for various crops to that of raising animals before considering solutions for increased access to safe drinking water worldwide....

Simulated acid rain, a dilute sulfuric acid solution, needs to be prepared for this demonstration. After a condensed lecture on acid rain, you will apply the solution to a sample of granite and a sample of limestone. Your young...

This is a week-long lesson on analyzing the similarities and differences between sources of tension and terrorism in eight locations around the world. The class is divided into eight groups and assigned one of the locations to research....

Students investigate the factors which affect corrosion. In this corrosion lesson plan, students experiment with 2 nails, copper wire and magnesium ribbon placed in a petri dish of agar solution, potassium ferricyanate and an indicator....

Walk your scholars through the process of finding percentages using this problem-solving worksheet! A word problem asks students to figure out how many pieces of a puzzle are left, if the completed 750 pieces make up 60% of the total....

In this solving inequalities worksheet, students add and subtract to isolate the variable for 26 inequalities. Each solution is then graphed on a number line.

Students consider alternative decisions and consequences. In this decision making lesson, students role-play in a social problem. They look for a realistic solution based on advantages and disadvantages.

Explore plot structure by analyzing text samples with writers. They define terms such as problem and solution, cause and effect, and story arc. They also identify the sequences used in modern stories by reading samples and determining...

In this telling time learning exercise, students use fuses which burn at different times to tell times in 45 minute increments. They solve this number puzzle and check their answer with an online solution.

The first two pages provide a chart to complete with results of a lab test using different solutions and indicators. The data analysis questions will help your students understand the concentrations of the solutions and how they affect...

An overview of acid and base compounds and their reactions is presented with this handout. Pupils name compounds and write chemical formulas. They write net ionic equations and explain how acidic solutions might conduct electricity. This...
