Middle schoolers use problem solving skills to examine symptoms, causes, and treatment of tuberculosis in modern times and in early 1900s. Students read patient case, work in teams to diagnose illness, and conduct Internet research to...

In this calculus instructional activity, students solve the function using the derivatives. They use properties of derivative and trigonometry to help them find the trig values. There are 28 problems.

Prompt scholars to complete a magic square using only variables. Then they can attempt to solve a numerical magic square using algebra. 

There is more than one way to solve a multiplication problem, and many learners find that the lattice multiplication method can be a helpful one. Fourth graders take an initial formative assessment before working in groups of two or...

Collaboration is the key for this equation-solving lesson. Learners solve a multi-step linear equation that requires using the distributive property. Within collaborative groups, scholars discuss multiple methods and troubleshoot mistakes.

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,...

This resource sneaks in the math so your learners will be adding and subtracting positive and negatives on a number line while thinking they are mapping out houses. The activity starts by putting houses the appropriate distance away from...

Help your learners understand dividing with fractions by using these methods to solve. Chose from two different number lines or linker cubes.  This practices "how many groups?" style division problems which help them comprehend why...

Which rate is greater and by how much? Pupils continue to compare rates to solve problems in the 20th portion of a 29-part series. Rates are presented in a variety of representations either using the same representation or different...

Learners will shout "Eureka!" in this quick but deep activity replicating the famous bathtub experiment of Archimedes. Given the scenario of a king with a suspected fake crown, young investigators develop formulas using density to...

Here is another opportunity for math students to apply reasoning to solve real-world problems with ratios. The ratio of the number of votes for two candidates is provided. Your class is asked to use this ratio and information given about...

Sophomores can be sometimes wise and sometimes foolish. The same can be said for their behaviors. After watching a presentation about risk taking behaviors, class members discuss the presentation in small groups, and then complete a...

Warm-up pupils' fraction muscles with a four-question quiz, then delve into a learning game designed to reinforce the concept of simplifying fractions. Based on the "I do, We do, You do" method of teaching, the lesson directly...

Scholars first investigate relationships in the side lengths of 30°-60°-90° triangles and 45°-45°-90° triangles. This knowledge then helps them solve problems later in the lesson about special right triangles.

Make math much simpler with mental math methods. The 16th installment in a series of 21 looks at ways scholars can apply mental math to convert division problems into easier problems with the same quotient. Multiplying or dividing both...

Scholars demonstrate understanding of kinematic graphs through matching dot graphs to position time graphs, dot graphs to velocity graphs, and a mixture of the two. If users feel stuck or confused, a Help Me! button offers an explanation...

Join the resistance—Ohm! Scholars apply Ohm's Law to problems of increasing difficulty as part of a series on electric circuits. The lesson begins with simply doubling and tripling voltage or resistance. It ends with having pupils solve...

Home is where your displacement is zero. Scholars practice solving distance versus displacement problems of increasing difficulty. They begin with two stage motion and, by the wizard level, each problem has four stage motion to consider....

Develop a sketchy approach to solving quadratic inequalities! Using a sketch of a graph, the presenter shows a way to solve quadratic inequalities. Pupils then practice that method to solve their own quadratic inequalities and apply the...

What starts as a basic question of division and remainders quickly turns abstract in this question of related ratios and radii. The class works to surround a central coin with coins of the same and different values, then develops a...

Pupils try to get a collar on temperature with a short assessment item that asks them to compare two different methods in converting Celsius to Fahrenheit. Individuals try to find out when an estimation provides conversions that are...

Is that a right triangle or a wrong triangle? Young mathematicians look at eleven different shapes and use a measuring tool of their choice to determine which triangles have right angles. Consider cutting out sets of the shapes to...

Examine the importance of sequence and series through contextual situations. Here, learners partake in a five-day unit that begins with the basics of arithmetic and geometric sequences and series. As it progresses, pupils apply the...

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...
