The context of this task is that a quarter was put into a bank account in 1901 and students are asked to calculate its value in 2013 at two different interest rates. Those amounts are compared to the appreciation rate of a rare and...

For this task, students are asked to interpret equations representing a bank account's balance where the interest is compounded monthly versus yearly. Aligns with A-SSE.A.1 and A-SSE.A.1.a.

A concise test for assessing number sense using weights and scales. Assessment is scored online offering students immediate feedback. Can be used for a quick assessment.

A simple tutorial that includes interactive activities and videos to introduce the law of conservation of mass.

Students will understand and apply the Law of Conservation of Matter; balance chemical equations; use the following skills: observing and recording data (observations) and making inferences from observations.

Young scholars use colored marshmallows (representing atoms) to construct compounds and arrange them into a balanced chemical equation.

This lesson introduces students' to Activity Center. In this lesson, students will explore the effect of compound interest on the amount of an investment over time. Students will work in small groups (or individually) to calculate...

In this lesson, students will be re-introduced to the Four Step Problem - Solving Plan. The plan will be used as a 'checks and balance' tool for discovering the roots (solutions) of polynomial functions. Students will: *Explore the...
