Students explore the concept of finding the area between two curves. In this finding the area between two curves instructional activity, students model the logos of McDonalds, Nike, and Motorola on grid paper. Students find functions to...

Students investigate how to make change when purchasing items.  In this making change lesson, students examine a scenario to calculate the correct change.  Students play Bingo based on information and calculations to determine...

Second graders create arrays to study multiplication. In this multiplication lesson, 2nd graders split into teams to complete a multiplication table. One team uses addition to solve the table while the other uses multiplication. Students...

In this algebra worksheet, students solve linear equations using one and two steps. They solve systems of equations using substitution and elimination with graphing. There are links for ready made tests and quizzes.

Learners factor trinomials and other quadratic functions. In this algebra lesson, students solve trinomials containing negative and positive coefficients. They factor quadratics of difference squares as well as regular polynomials.

Students explore the role of protest songs. In this early American history lesson, students research the acts passed by the British that angered colonists. Students then listen to protest songs from contemporary American history prior to...

Students use ratio and proportions to solve problems. In this geometry lesson, students apply ratio and proportions to real life scenarios.

Students collect and record data. In this early data analysis lesson, students gather data about their partners face. As a class, the students use tally marks and pictographs to record the data and answer question about the information...

Students investigate different online tutorials as they study graphing. In this graphing lesson, students apply the concept of graphs cross curricular and use it to make predictions. They define the purpose and theories behind graphs.

Should Fred receive a certificate for scoring in the top 2.5% of a statewide standardized test? Given the test scores for a large population and the mean and standard deviation, young scholars will decide if Fred's score is good enough....

This problem examines equations defining different circles in the x-y plane. Students must use the Pythagorean Theorem to find equations whose solutions are points on the circle and explain why they work. Includes a GeoGebra worksheet...

This task can be used for assessment, practice or even to motivate students via an in-class discussion of why it is useful to rewrite exponential expressions in equivalent forms. Aligns with A-SSE.B.3.c.

This task serves as a possible first student exploration after an initial introduction to the form and arithmetic of complex multiplication. Students need to understand that every complex number can be expressed in the form a+bi, and...

This task compares the usefulness of different forms of a quadratic expression. Young scholars have to choose which form most easily provides information about the maximum value. Aligns with A-SSE.B.3.

The purpose of this problem is to rewrite simple rational expressions in different forms to exhibit different aspects of the expression, in the context of a relevant real-world context, in this case, the fuel efficiency of a car. A-APR.D.6.

This task could form part of a classroom activity where students are encouraged to find as many different ways as possible to make different fractions such as 1/12 and then share their methods. While measuring cups would be helpful to...

Help Jane sell her Forrester! Using the data given, students will make an appropriate plot with well-labeled axes that would allow you to see if there is a relationship between price and age and between price and mileage. Students are...

In this task, students are shown three unit squares and two line segments connecting two pairs of vertices. They are asked to find the area of a triangle formed by intersecting lines. They can solve it using coordinate geometry or...

Satellites communicate with a GPS device and establish the distance between them and their locations. The set of points at a fixed distance from a satellite form a sphere so when the GPS receives its distance from a given satellite, this...

In this task, students are asked to draw a quadrilateral so that no two sides are congruent, no two angles are congruent, and no two sides are parallel. The task gives students the opportunity to prove that if we join the midpoints of a...

This active counting game gets the kids up and moving! Students form a circle and start counting around the circle one by one until the last number (chosen ahead of time by the teacher) in the sequence is reached. When the last number is...

This activity will test how quickly students can count objects. The teacher will assemble a variety of groups of objects in a few different forms (examples included). Students will race against the clock to sort the groups of objects...

The purpose of this task is to introduce young scholars to an exponential decay function in the form f(x) = abx, with a concrete interpretation of the decay factor b. A table shows the rebound height of a basketball for each successive...

Students will stand and form a circle facing in toward each other. The teacher will select a counting sequence to be practiced with no more than 6-10 numbers. The students will start counting around the circle one by one until the last...
