Waterton-Glacier International Peace Park includes whitebark pines that are over 1,200 years old, meaning they have been there since before medieval times. The second lesson of five details how to read tree rings for climate change and...

In this ESL math vocabulary worksheet, students answer a set of 43 math questions, solving problems covering a variety of concepts. Page has a link for audio and HTML code.

Fourth graders practice multiplication and division with cooking recipes. In this math lesson, 4th graders look at a recipe and change it so that it works for twice as many people or half as many people. 

Students study addition of fractions with like denominators using illustrations and problem solving.

Pupils draw the graph of a door opening and closing over time. They graph a given function on their calculators, create a table of values and interpret the results by telling if the door is opening or closing and evaluate the average...

Learners explore lists and determine the derivative for that list. They use regressions to discover equations. 

Explore 5 classical problems of algebra.  They will solve problems involving Heron's formula, fractional equations, vector equations, apollonius' sphere, and transversals. The idea is to lead to new perceptions and visual...

Calculus students find the limit of piecewise functions at a value. They find the limit of piecewise functions as x approaches a given value. They find the limit of linear, quadratic, exponential, and trigonometric piecewise functions.

Investigate rational exponents in this math lesson. Scholars make conjectures about the relationship between rational exponents and radicals. They then use their Ti-Nspire to simplify rational exponents.

Here is another in the interesting series of lessons that use the special State Quarters as a learning tool. This one uses the California State Quarter. During this activity, pupils learn the many ways they can conserve natural resources...

In this geometry learning exercise, students create circle, line and bar graphs using different comparisons of events. There are 24 questions with an answer key.

Take the old baking soda and vinegar volcano to the next level by using it to study repeated lava flows over time, examine geologic features on Earth and Mars, and speculate about some of the formations on Mars. 

Students, in groups, make chocolate chip cookies following a recipe.

Students explore beginning division. For this division number properties lesson, students solve simple division story problems using cookies. Students create models that represent the identity and zero properties, then write explanations...

In this adding mixed numbers with and without regrouping activity, students sharpen their problem solving skills as they solve 6 story problems.

Third graders are introduced to how to divide by 3 and 4. They are told that are going to use the same procedures as they did on yesterday, except with new divisors. Students turn their attention to the Paddle Problem on page 206 of...

In this percent of a number worksheet, students solve a series of 6 word problems. Students are given "hints" to help solve problems 1 and 2.

Students apply fraction multiplication and division to recipe conversion.

A TI-nspire instructional activity to find determinants of matrices using calculators. The class follows along in this step by step activity to explore operations on matrices. They will mostly be multiplying and at the end of the...

Explore the concept of systems of equations in two variables and use matrices to solve them. Young mathematicians enter coefficients and constants into a matrix and then solve using row reduction. Instructions on how to use the shortcut...

Learners investigate matrices by exploring addition, subtraction and multiplication of matrices.  Students find the determinant and inverse of a matrix.  The lesson includes a set of practice problems

A TI technology activity that helps learners to recognize and use the characteristic of a perfect square quadratic to complete the square. Additionally, they apply their knowledge to solve real-world problems.

Solve equations by completing the square. The pupils factor quadratic equations and graph the parabola. They also identify the different terms in the equation and look for patterns.

Investigate the Fundamental Theorem of Algebra and explore polynomial equations to determine the number of factors, the number of roots, and investigate multiplicity of roots.
