Figure out what to do when there is no grid to count. Using a ruler and a sharp pencil, the narrator shows how to perform a dilation when the figure is not on a grid. The ray method works by drawing a ray from the center of dilation...

It's pass or fail, and one must pass to move on to the next lesson—no pressure. The second of seven installments in the Off the Grid unit has pupils demonstrate their knowledge of vocabulary as well as the process of using a multimeter....

Introduce learners to two methods to estimate the formula for the area of a circle. The first method uses a sector of a circle to form a rectangle, and the other uses grids to estimate the area. The problems in the 18th segment of a...

The Golden Ratio. The Divine Proportion. Yup. It's math and art blended into one colorful activity. Young artists combine colored tissue paper circles and parts of circles to create geometric patterns. As a bonus, kids get to figure out...

Stretch out the grid. Teaching modules provide suggestions on how to use the case study, GridWorld, throughout the year as opposed to only right before the exam. The instructional units provide suggestions for presentations, assignments,...

The works of Carol Ann Duffy, Scottish poet and Britain's 2009 poet laureate, serve as a model for a writing activity that asks class members to select a character card, brainstorm lists of words, phrases, actions, and items associated...

Find the distance between various locations in a neighborhood. Scholars use the interactive to find distances between locations on a map. The map is overlaid onto a grid to provide coordinates for each location, and pupils apply...

How will a scale factor affect a figure—negatively? Using a grid, the narrator of an engaging video performs a dilation with a negative scale factor. The presenter compares a positive scale factor with a negative scale factor to explain...

Challenge the young mathematicians to find the exact coordinates of a dilated point. The fifth segment in a 16-part series introduces the class to the converse of the Fundamental Theorem of Similarity. Scholars use the theorem to...

How are maps like fish? They both have scales. The chapter includes six different activities at three different levels. Scholars complete activities using natural resources, learn how to read a map, see how to make a compass rosette,...

Explore how to graph lines from different pieces of information. Scholars learn to graph linear functions when given an equation, given two points that satisfy the function, and when given the initial value and rate of change. They solve...

Spin a wheel, land on a color ... and win. Learners create a graph to display the probabilities of the amount of money they can win by spinning a colored wheel. The pupils use the dollar amounts and their probabilities to calculate the...

Create an understanding of solving problems that require more than one equation. The lesson introduces the concept of systems of linear equations by using a familiar situation of constant rate problems. Pupils compare the graphs of...

How can we locate places? Maps, of course! Expose second graders to the tools available in maps and discuss how these tools can help people find locations. Students also look at communities, including what makes a community and the...

Max out heart rates for males and females. Formulas of maximum heart rates provide the equations for a linear system. Pupils use the interactive to graph the equations for males and females and determine their points of intersection. The...

The energy is not really lost, it is just converted to a different form. Pupils learn about the conversion of energy in the fifth segment of an energy unit with six parts. Learners develop an understanding of the conservation of energy...

Learn how to display data. Young data analysts watch a video to review how to create cumulative frequency histograms and box plots. They work on a set of questions to practice producing these data displays.  

Making decisions can be very difficult. Show your class one way to evaluate choices with this lesson, which is inspired by the book Glo Goes Shopping. Learners practicing using a decision-making grid with the content of the story and a...

Assertive communication is an acquired skill. Teaching young people to ask for what they need and to believe that they have a right to ask is at the core of a unit on assertive communication. Over the course of the unit, middle and high...

Engage young mathematicians in applying their knowledge of area and perimeter with a fun geometry instructional activity. Through a series of problem solving exercises, children use their math knowledge to design...

What are your pupils' homes like? Incorporate their homes into a drawing lesson plan. Using an enlarged photograph, class members draw a grid so they can easily split their drawing in half. The final product should demonstrate cool...

Think it through! That's the big takeaway from a series of lessons about decision-making. Young scholars engage in a series of exercises and activities designed to urge them to look at options, the pros, and cons of a course of action,...

The fifth lesson of seven in the series outlines an in-depth analysis of the periodic table. After direct instruction, pupils take turns practicing in the group before beginning independent study. The assessments include a...

Scholars warm-up their map skills with a discussion using location words to describe familiar places. An engaging video informs class members about latitude and longitude. Three leveled activities extend the learning experience for...
