The object is to model fraction division by asking “How many are in one group?” It is a difficult concept to understand, but developing the model that shows one cup to a certain amount of container or one container to a certain amount of...

Word problems offer class members an opportunity to learn the concept of solving linear systems using graphs. Individuals choose a problem based upon preferences, break into groups to discuss solution methods and whether there...

Scholars become STAR deputies in a lesson that encourages them to be problem-solvers. Small groups gather to complete a worksheet by answering questions. A discussion presents a scenario in which a problem occurs on the playground. Small...

Division can be seen in two ways; as splitting a whole into a certain number of pieces, or splitting it into pieces of a certain size. Help your class reach this understanding with these two simple word problems. Encourage the use of...

Just how big would it really be? Young mathematicians determine if different toys are proportional and if their scale is accurate. They solve problems relating scale along with volume and surface area using manipulatives. The...

Try to figure out what happens with shadows as a person moves between two light sources. A formative assessment lesson has individuals work on an assessment task based on similar triangles, then groups them based on their...

Concepts are only valuable if they are applicable. An informative resource uses concepts developed in lessons 26 and 27 in a 36-part series. Scholars write equations and solve for missing side lengths for given right triangles....

Study the 16 Habits of Mind with a professional resource. Based on Describing 16 Habits of Mind by Arthur L. Costa and Bena Kallick, the resource details 16 ways learners perceive problems around them and produce ways to deal...

As high schoolers seek to grow more and more independent, they must constantly make choices. Some options are healthy and some not so much. To begin the discussion, class members are asked to identify five safe and healthy (or...

Use this resource to teach perimeter of regular plane shapes, measurement, rounding, and systematic problem solving skills. There are 78 complete slides and two game suggestions intended to facilitate content understanding.

Learning how to write computer code has never been so much fun! Given control of their very own robots, children create simple programs in order to solve a series of challenges and develop their problem solving skills.

How do you operate with numbers in scientific notation? The resource provides examples on how to divide and multiply with numbers written in scientific notation. The handout and video also cover the procedure for addition and subtraction...

Put all that algebra learning to use! Using algebraic strategies, learners solve three-variable systems. They then use the three-variable systems to write a quadratic equation given three points on the parabola.

What to do with more than one variable? Part of a larger series, the video shows how to solve a formula for another variable. Pupils solve equations with more than one variable for a given variable of interest. Problems include linear,...

The Milky Way gets great reviews on Trip Advisor — 100 million stars. The activity allows scholars to rethink their assumptions and prior knowledge. Pupils observe a set of two lights at equal distance and brightness, but they believe...

Young scholars examine the concepts of power and authority as they begin learning about government in this elementary social studies lesson. Through a series of readings, discussions, and problem solving activities, children...

Tie the unit together and see concepts click in your young mathematicians' minds. Scholars apply the properties of similar triangles to find heights of objects. They concentrate on the proportions built with known measures and solve to...

Whether it's counting marbles, flowers, or playing cards, small objects can add up to great sums. Learners work six story problems to practice addition to 100. Some regrouping is required, along with distinguishing useful from irrelevant...

What is the most efficient way to ensure everyone is connected? Individual pupils determine the least expensive route to pave roads in a fictional city. In doing so, they learn to find the minimal spanning tree for the situation. They...

Are complex numbers and binomials similar? This stack of slides provides an introduction to complex numbers and shows how to operate with them. The worked examples show a connection between operating with binomials and operating with...

How can you make solving radical equations more engaging? Provide your math class with a hands-on activity that focuses on solving radical equations with flash cards. A warm-up and exit ticket flank direct instruction of the steps...

Nothing fancy here ... just your run-of-the-mill Algebra party! Learners explore the patterns of linear functions while designing seating arrangements for a dinner party. Comparing the number of tables to the perimeter of the combined...

Sometimes the interview process includes negotiating for what you want. Here's an activity that guides job seekers to achieve The Best Alternative to a Negotiated Agreement (BATNA). Participants take on the role of job seekers and...

How high can your pupils jump? Learners design an experiment to answer this question. After collecting the data, they create box plots and scatter plots to analyze the data. To finish the lesson, they use the data to draw conclusions.
