Math Curriculum Mastery® Flip Charts provide comprehensive coverage of key standards-based curriculum in an illustrated format that is visually appealing, engaging and easy to use. Curriculum Mastery® Flip Charts can be used with the entire classroom, with small groups or by students working independently. Each Math Curriculum Mastery® Flip Chart Set features 10 double-sided laminated charts covering grade-level specific curriculum content on one side plus write-on/wipe-off charts on reverse side for student use or for small-group instruction. Built-in sturdy free-standing easel for easy display Spiral bound for ease of use Activity Guide with black-line masters of the charts for students to fill-in, key vocabulary terms, corresponding quiz questions for each chart, along with answers Ideal for Learning centers In class instruction for interactive presentations and demonstrations Hands-on student use Stand alone reference for review of key science concepts Teaching resource to supplement any program HOW TO USE Classroom Use Each Curriculum Mastery® Flip Chart can be used to graphically introduce or review a topic of interest. Side 1 of each Flip Chart provides graphical representation of key concepts in a concise, grade appropriate reading level for instructing students. The reverse Side 2 of each Flip Chart allows teachers or students to fill in the answers and summarize key concepts. Note: Be sure to use an appropriate dry-erase marker and to test it on a small section of the chart prior to using it. The Activity Guide included provides a black-line master of each Flip Chart which students can use to fill in before, during, or after instruction. On the reverse side of each black-line master are questions corresponding to each Flip Chart topic which can be used as further review or as a means of assessment. While the activities in the guide can be used in conjunction with the Flip Charts, they can also be used individually for review or as a form of assessment or in conjunction with any other related assignment. Learning Centers Each Flip Chart provides students with a quick illustrated view of grade-appropriate curriculum concepts. Students may use these Flip Charts in small group settings along with the corresponding activity pages contained in the guide to learn or review concepts already covered in class. Students may also use these charts as reference while playing the NewPath’s Curriculum Mastery® Games. Independent student use Students can use the hands-on Flip Charts to practice and learn independently by first studying Side 1 of the chart and then using Side 2 of the chart or the corresponding graphical activities contained in the guide to fill in the answers and assess their understanding. Reference/Teaching resource Curriculum Mastery® Charts are a great visual supplement to any curriculum or they can be used in conjunction with NewPath’s Curriculum Mastery® Games.

Tables Collecting data You can collect data (information) from other people using polls and surveys. Scientists collect data from experiments. Tables and graphs help us organize and interpret collected information. The mean is the average of a set of numbers. To find the mean, add all the numbers in the set and divide the sum by the number of items in the set. The median is the middle number when the data are in numerical order. The mode is the number that occurs most often in a set of data.

Congruence & Similarity Symmetry 1 line of symmetry 4 lines of symmetry line of symmetry mirror placed through the middle of letter A 3 lines of symmetry Transformations Flips, Slides & Turns The three main transformations are: The reflected part of letter A on the mirror looks exactly the same as the original part. Similar figures are identical in shape, but not in size. A figure has line of symmetry if it can be folded or reflected into two congruent parts that fit on top of each other. The fold line or line of reflection is called the line of symmetry. Shapes can be congruent if one of them has been transformed by sliding, flipping or turning. The figure is moved along a straight line. The figure is flipped over a line creating a mirror image. The figure is moved around a point. Congruent figures are identical in both shape and size. © Copyright NewPath Learning.

A straight angle forms a straight line. A right angle forms a square corner. Place the center point of the protractor over the vertex (corner) of the angle. Draw the ray DF. Place the center point of the protractor on the end point of the ray. Line up the ray DF so that it passes through the mark of the protractor. Make a mark at 115º and label it E. Draw ray DE from the end point of ray DF to the mark you made at 115º. Place the protractor so that ray AC is over the base line of the protractor and passes through the mark. Read the measure where the other ray AB crosses the protractor. An acute angle is less than a right angle. An obtuse angle is greater than a right angle. A ray is part of a line with one endpoint and goes on forever in the other direction. A line segment is part of a line between two endpoints. A line is a straight collection of points that extend in two opposite directions without end. A point is a location in space.

C = d or 2 r C = r 2 Area of a Circle Circumference of a Circle A E AB is a diameter AD, DB, and DC are radii EF is a cord B D C F center diameter circle D circumference radius chord A circle is a plane figure formed by a set of points that are equal distance from a fixed point within it, called the center. The diameter of a circle is the distance across the inside of a circle through the center. It is twice the measure of a radius. The radius is half the measure of a diameter. It is a line segment with one end point at the center of the circle and the other endpoint on the edge of the circle. The circumference of a circle is the distance around it. A chord is a line segment that connects any two points on a circle. The area of a circle is the space contained within the circumference. The ratio of the circumference of a circle to the diameter of a circle is approximately equal to 3.14 or . This ratio is called Pi ( ) and is the same for all circles. 22 7 d = 12 in. ; A = ? d = 12 A = r 2 A 3.14 (6) 2 A 3.14 36 A 113.04 in.2 C = 2 r C 2 3.14 5 C 31.4 ft r = 6 r = r = 5 ft ; C = ? d 2 r = 12 2 12 in. 5 ft C = d C 3.14 10 C 31.4 ft d = 10 ft ; C = ? © Copyright NewPath Learning.
