In this animated object, learners follow a process for simplifying radicals.
Learners follow steps to add fractions with different denominators. They also review fraction concepts, do a drag-and-drop exercise involving fraction terms, and add fractions with common denominators. Resource from Wisc-Online: free access but sign-in is mandatory.
In this animated and interactive object, learners use an algebraic formula to solve a problem involving distance, rate, and time. Resource from Wisc-Online : free access but sign in is mandatory.
This lesson focuses on having students make connections among different classes of polynomial functions by exploring the graphs of the functions. The questions in the activity sheets allow students to make connections between the x-intercepts of the graph of a polynomial and the polynomial's factors. This activity is designed for students who already have a strong understanding of linear functions, some knowledge of quadratic functions, and what is meant by a polynomial function.
This activity explores the measurement of the amount of blood being pumped by a heart. The goal of this investigation is a rich exploration of rates of change and accumulation in context. As presented here, the measurement is done from a discrete perspective, but the generalization to a continuous perspective and use of calculus (integrals) can be done easily. The measurement is based upon two common problems: (1) a flow rate and accumulation problem and (2) a concentration problem. Given a flow rate, a concentration of ice water and a duration, how much ice water is pumped over the time interval? How can you determine the concentration of ice water by measuring the temperature of the mixture? The activity is separated into four parts. These four segments are available at the bottom of every page.
