No need to be exact every time. Pupils watch an engaging video on approximating function values. They see how to write the equation of a tangent line, use it to calculate approximations, and then determine whether it is an overestimate...

The inverse of matter is anti-matter, so the inverse of a derivative is an antiderivative. The lesson introduces antiderivatives and indefinite integrals to the class along with the notation for integrals. Groups work together to find...

Students investigate the broad range of jobs that can be found in the world of design. Students explore sound design, language architecture, etc. Students design a resource book and post it on a website for others to share.

Young mathematicians put one foot in front of the other as they learn how to measure length in an elementary math lesson. Using paper cutouts of their own feet, children measure classroom objects as they discover the importance of...

Model for your young mathematicians the process for converting repeating decimals to fractions. To demonstrate their understanding of the process, class members then complete and assessment task and participate in an activity matching...

Scholars learn to order rational numbers in the seventh lesson in a series of 21. Reasoning about numbers on a number line allows for this ordering.

For this explaining solutions worksheet, students read the word problem and then use the steps of understand, plan, solve, and look back to help them solve the problem. Students also explain the solution.

Students design a project for solutions for pollution problems at the Lake Pontchartrain Basin. In this pollution lesson plan, students research the pollution problems and solutions for Lake Pontchartrain. Students answer the questions...

In this solving word problems worksheet, students read a problem and write word answers for each step to find the solutions and then apply these steps to solve a word problem to determine if the answer is reasonable.
