Congratulations on your purchase of the Really Good

Stuff® Measuring Angles Poster—a step-by-step

reference for measuring right, acute, and obtuse angles.

Included in this Really Good Stuff® set you’ll find:

• Measuring Angles Poster, 19" by 24"

• This Really Good Activity Guide™

Measuring Angles Poster ActivitiesShare the poster with students. Begin by reading the

definition of an angle out loud for students, then point

out each type of angle and read its definition. Explain to

students that measuring angles is done with a

protractor, then point out the protractor on the poster.

Choose students to read the step-by-step directions for

measuring an acute angle, then explain that since the

bottom ray is pointing to the right, they will need to read

the numbers along the outside of the protractor. Use a

colored write-on/wipe-off marker to make another 50˚

angle pointing to the left to demonstrate how the inside

numbers on the protractor are used to measure angles if

the bottom ray points left. Next, choose students to

read the step-by-step directions for measuring an

obtuse angle, then explain that since the bottom ray is

pointing to the right, they will need to read the numbers

along the outside of the protractor. Use a write-on/wipe-

off marker to make another 120˚ angle pointing to the

left to demonstrate how the inside numbers on the

protractor are used to measure angles if the bottom ray

points left. If desired, use the write-on/wipe off marker to

demonstrate making a right angle on one of the

protractors on the poster. Have students practice

making angles at the board and identify them as right,

acute, or obtuse.

Measuring Angles ReferenceGive students their own reference sheet for measuring

angles by making copies of the Measuring Angles

reference reproducible found in this guide. If desired,

three-hole punch the sheets so students may keep them

in their math notebooks or take home to help with

homework assignments.

Let’s MeasureLet your students have some practice measuring right,

acute, and obtuse angles. Make copies of the Let’s

Measure reproducible found in this guide. Give students

copies of the reproducible and have them cut off the

protractors along the dotted lines. Next, have them

carefully cut around the images of the protractors so

they may use them to measure the angles on their

sheets. Be sure to remind students to line up the vertex

with the center point on the protractor and one ray

along the bottom. Before students begin, review which

numbers to read on the protractor according to the

direction the bottom ray is pointing. You may wish to

circulate among students to make sure they are using

the protractors properly. After students have completed

their sheets, display the work around the poster.

Angle PoemGive your students an easy-to-remember rhyme to help

them identify right, acute, and obtuse angles. Make

copies of the Angle Poem reproducible found in this guide.

Three-hole punch the sheets and give to students to

keep in their math notebooks. You may wish to enlarge

a copy for classroom display.

Investigating Solids

Helping Teachers Make A Difference®


Stuff® Investigating Solids Poster featuring the faces,

edges, and vertices of a sphere, a cylinder, a cube, a

pyramid, cone, and a rectangular prism.


• Investigating Solids Poster, 19" by 24"


Investigating Solids Poster Activities

Share the poster with students. Explain to students

that geometric solids have certain characteristics that

help describe their shapes—the number of faces, the

number of edges, and the number of vertices. Point out

the three boxes at the top of the poster and read each

definition out loud for students. Point out the boxes

featuring the flat-surface solids and explain to students

that some solids have surfaces that are flat. Choose

students to point out the faces, edges, and vertices for

each flat-surface solid. Explain to them that some solids

have curved surfaces and choose students to point out

the curved surf a c e s, faces, and ve rtices for each

curved-surface solid.

Building Models

Let students have some hands-on experience with faces,

edges, and vertices by creating 3-dimensional models of

solids. Enlarge and make copies of the Solids patterns

found in this guide. Give copies of each solid pattern to

students. Have students color their patterns if desired,

then cut them out and assemble them according to

the directions. After

the models are

completed, have

students review

the poster by

counting the

number of

faces,

edges, and

vertices on their

models. Display the models on a

table or pin the models to a bulletin board titled

We’re Building Our Knowledge of Solids.

Real Life Solids

Challenge your students to a fun game of Real Life

Solids. Divide your students into cooperative groups,

then give each group a number and a copy of the game

sheet found in this guide. Explain that the object of the

game is to name as many real-life solids as possible

during a 15 minute period. For example, in the column

labeled sphere, they might write orange, globe, ball,

marble, etc. Then, set the timer to 15 minutes and let

the challenge begin! While groups are filling in their game

sheets, label a piece of chart paper with the names of

the solids, leaving plenty of room to write a list of

objects named by the students. When time is up, have

groups share their answers for each solid while you

record the names of the objects on the chart. Be sure to

recognize the groups with the most correct answers for

each solid.

Exploring Plane Figures



Stuff® Exploring Plane Figures Poster to define and

illustrate the sides, the vertices, and the angles in

geometric plane figures.


• Exploring Plane Figures Poster, 19" by 24"


Exploring Plane Figures Poster ActivitiesShare the poster with students. Explain to them that

geometric plane figures have certain characteristics that

help describe their shapes—the number of sides, the

number of vertices, and the number of angles. Point out

the three boxes at the top of the poster and read each

definition out loud for students. Point out the boxes

featuring the plane figures. Choose students to name

each figure and point out the sides, vertices, and angles.

Ask them if they see a pattern in the information, looking

for a student to say that the number of sides, vertices,

and angles is always the same.

Exploring Plane Figures ReferenceGive students their own reference sheet for plane figures

by making copies of the Exploring Plane Figures reference

reproducible found in this guide. If desired, three-hole

punch the sheets so they may keep them in their math

notebooks or take home to help with homework

assignments.

Exploring Plane Figures Times Three Make copies of the Exploring Plane Figures reproducible

found in this guide. Then use the reproducible in one of

the following ways to suit your students’ needs.

1. When first introducing the skills on the poster, give

copies of the reproducible to students and have them

work together to fill in the sheets. Display the poster

in an accessible area and allow students to use it as

reference while completing their work. Display the

students work around the poster.

2. After students have become more familiar with plane

figures, use this reproducible as a homework

assignment to involve parents in the skills you are

working on in math. Have them take home their sheets

and ask them to work with their families to fill them in.

Have them find items around their houses that are

plane-figure shapes and list them on the backs of their

papers. When students return their assignments to

school, have them share their lists of items from the

backs of their sheets while you record their items on a

piece of chart paper labeled with the plane figure names.

3. Use the reproducible as an assessment for what

students have learned. Be sure to take down or

turn over the poster during assessment time.

Included in this Really Good Stuff® set you’ll find:• Constructing Tessellations Poster, 19" by 24"• This Really Good Activity Guide™

Constructing Tessellations Poster ActivitiesShare the poster with students. Make a copy of theShapes patterns found in this guide. Enlarge the square,diamond, and triangle patterns, and cut them out on the thick black lines. Begin by reading the definition oftessellation out loud for students and have them look atthe examples in the center of the poster. Ask them wherethey might see similar tessellations (wrapping paper,table cloths, quilts, etc.). After several students haveshared ideas, explain that tessellations are constructedby using a shape pattern, then sliding, flipping, or turningthat shape and tracing around it. Read the Using Slidesinformation out loud for students. Next, place theenlarged square pattern on the board or on a piece ofchart paper and trace around it. Demonstrate sliding thepattern and tracing another square directly beside it.Continue sliding the pattern and tracing around it todemonstrate constructing a tessellation by sliding ashape. Complete the above steps with the Using Flipsand Using Turns sections on the poster. Point out theThese Shapes Tessellate and the These Shapes Do NotTessellate sections at the bottom of the poster. Giveeach student a different shape pattern from thepatterns copied above and have him or her try toconstruct a tessellation on a sheet of paper by sliding,flipping, or turning the pattern. Have students sharetheir discoveries with the class and discuss whichshapes tessellate and which shapes do not.

Explain to students that you want to make a large classroom quilt display using tessellations. Givestudents copies of the Tessellation Quilt reproducibleand have them create and color their own tessellationsquares. After the squares are finished, have studentscut them out and put their names on the backs. Collectall of the squares, then create a quilt by tiling thesquares together in a colorful display titled Our ColorfulTessellation Quilt.

Create a Tessellation BoardChallenge your students to identify additional shapesthat tessellate and do not tessellate. Cover a bulletinboard in butcher paper and divide it in half with a piece of yarn. Label one side These Shapes Tessellate and the other side These Shapes Do Not Tessellate. Then,encourage students to look at shapes as they gothrough their day and think about whether they wouldtessellate or not. Place several 2" by 2" pieces of whiteconstruction paper and several sheets of 9" by 12" pieces of white construction paper in an accessiblelocation near the board. Challenge students to use thesmall sheets to cut out new shapes to add to each side of the bulletin board. Have them use a larger sheetof paper to trace their new shape and prove or disprovetessellation. Allow them to color their large sheets,then attach them along with their shapes to the bulletin board.
