Count on the scale to enlarge a figure. The video shows how to create an enlargement given a scale factor and a center of enlargement. The presenter multiplies the vertical and horizontal distance by the scale factor to find the new...

Make enlargements with and without centers. Pupils work through seven problems dealing with dilations or enlargements. The first couple items are strict enlargements without centers, while the others have centers. Class members also...

Help third graders make sense of the Common Core math standards with this simple checklist. By rewording each standard as an I can statement, children are provided with clear goals to focus on as they participate in math lessons.

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...

Enlargements make it bigger, right? A video shows viewers how to perform a basic dilation with a fractional scale factor. They learn how to use the scale factor to find the location of the transformed vertex by multiplying the horizontal...

Where did the transformation begin? Using a ruler, the narrator of a short presentation shows how to find the center of enlargement for transformed figures. Worksheets provide the class members an opportunity to practice the newly...

What caused that to happen? Using three aspects, a video demonstrates how to describe an enlargement or dilation. The presenter counts the lengths of the sides to determine the scale factor and a ruler to find the center of dilation.

Math is fun with a board game printable set. After printing the pieces and board for the game, have your kids play in groups to practice concepts such as operations and arithmetic formulas.

Any first grader can master the Common Core math standards with this checklist! With each standard rewritten as an affirmative I can statement, children are provide with clear goals to work toward throughout the school...

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...

Young geometers and biologists investigate the math of nature in an activity that is just the bee's knees. Participants will study the tessellations of hexagons in a beehive, along with the natural rationale behind the specific shape....

Enlargements and reductions are all about scale. The lesson plan introduces scale drawing to the class. Pupils determine whether the drawing is a reduction or an enlargement, and the constant of proportionality between the original and...

In this geometry activity, learners figure out the center of enlargement and the scale being used. They find the image and pre-image and label it. There are 7 questions.

In this math worksheet, students find the centre of enlargement, scale factor and label the images. The images give a perspective of how the size scale changes.

In this enlargement activity, 6th graders solve and complete 3 different types of problems. First, they enlarge the given shape by a scale factor of 3. Then, students find the scale factor of the next enlargement. Finally, they enlarge...

Double, toil ,and double linear dimensions. Learners first complete an assessment investigating how doubling linear dimensions affects the area of pizzas and the volume of popcorn containers. They then complete an activity investigating...

Learning division is a challenge for many young mathematicians, but this presentation on divisibility rules can make it much easier. Seven different rules are clearly explained and modeled with the support of multiple examples. Consider...

Classmates create a scale drawing from another scale drawing, changing the scale in the process. Groups enlarge or reduce the scale of the drawing and discuss their processes.

Geometry in life-sized dimensions! Using enlarged graph paper, pupils perform a series of transformations. By recording the initial and final placement of the images, they are able to analyze the patterns in the coordinates during a...

Students measure various dimensions of a male and a female dolls body and scale them proportionally to average human measurements. They calculate the appropriate scale factor (magnitude) to enlarge their doll and apply that scale factor...

Conduct research on the Internet about labyrinths and mazes to learn about proportions and ratios. Inquisitive minds design their own maze, one maze is chosen and proportionately enlarged to 20 feet by 30 feet. This is a fun challenge...

Engage scholars in a ratio lesson that employs real-world scenarios. Learners will compare the length and width of pictures and use a table to identify ratio patterns. They watch "Math Can Take You Places" and discuss jobs that use math...

Is it bigger, or is it smaller—or maybe it's the same size? Individuals learn to describe enlargements and reductions and quantify the result. Lesson five in the series connects the creation of a dilated image to the result. Pupils...

Guide young mathematicians through the crazy world of negative numbers with a handy reference document. Offering clear instructions for adding and subtracting positive and negative integers, this resource is a great way to...
