INTEGRATED THEMES
Science, Literacy, Art, Social Studies & Math Activities
What Do You Know? What Do You Wonder?
As you introduce this new theme, it’s important to acknowledge children’s
previous experiences You might open your study of frogs and toads by
ask-ing students what they already know about these animals As the discussion
unfolds, questions may arise, which you can record, along with the
informa-tion children share, in simple chart form An alternative to this opening is to
begin with a more focused set of questions: Where do frogs live? What do
they eat? How do they have babies? and so on Here again, you can record
children’s ideas in chart form
What do you know? What do you wonder?
They have long back legs.
They can jump
They have big eyes.
They eat bugs and slugs.
They have big mouths.
They like water.
Some are in the pond at
the park.
Questions about frogs and toads?
Where do they live?
What do they eat?
How do they have babies?
What do they do in the winter?
Do they all look alike?
Frogs and Toads
Do they have noses?
Do they have ears?
How can they breathe underwater?
How do they have babies?
or
Children’s answers to our questions often generate new paths of inquiry As
these come up, we turn them into “question bubbles.” Displayed on the wall,
these questions provide a focus for further research We often review them
Overview
The study of frogs and toads is a
fasci-nating topic, and you might make it an
integral part of your curriculum sometime
during the spring Following is a
collec-tion of ideas we’ve used in our own
classrooms to extend learning about
frogs into the rest of our program These
ideas bring science, literacy, math, and
art together in a variety of projects Plan
to incorporate these ideas into other
parts of your day over 2 or 3 weeks
Trang 6before we read a new book, watch a video, look at pictures, take a field trip,
or bring in live specimens This helps youngsters listen and watch for mation that will provide answers and confirm or correct the informationthey’ve already volunteered (For this reason, we record at the beginning ofthe study any student misinformation as well as things we know to be trueabout frogs and toads.)
infor-Once you’ve taken time for children to share what they already know and tobegin to generate some questions, you’re ready to start gathering information
Eggs, Tadpoles & Frogs Live Observation
You might consider gathering a few tadpoles and setting up a classroom rarium with pond water and plants You’ll need fish food, lettuce, and a rock forthem to climb as they begin to develop into frogs (Be careful not to get bullfrog
ter-tadpoles—they take a very long time to turn into frogs.) Be sure to return the
new froglets as soon as possible to the area where they were captured
To support this live-observation, you might also run copies of the phosis poem (see Blacklines 11–16) to turn into a wall chart, a big book or a
Metamor-“circle of life” display, in which the words and drawings shown below aremounted on butcher paper (folded lengthwise) and formed into a cylinder

Little tadpoles wriggling out of jelly,
Use their tails to swim around
to fill their little bellies.
They develop lungs
and grow hind legs,
Eyes-On Experiences Picture Walks
We like to set up picture walks in our classrooms These provide children with
opportunities to learn about a particular topic by studying illustrations and
photographs To set up a picture walk, we lay out a large photograph or two at
each table and set up clotheslines of pictures tied across a couple areas of the
room We’ve been able to find some calendars that feature large, beautifully
colored photos of frogs (We usually wait until after the new year to find
some on sale, and have been able to build up intriguing photo collections
over a couple of years.) We’ve also scanned pictures from books and set out
the books themselves
Trang 8It’s exciting to start the day with the picture walk ready for viewing If we’veposted some of the students’ questions, we review them before we launch thepicture walk Then we send children out in small groups or pairs to study thepictures carefully Our challenge to youngsters is to gather information withtheir eyes We let them know that if they’re very attentive to detail, theymight find out more about what frogs eat, where they live, how they behave,how they make their special sounds, how their feet differ, and what their ba-bies look like We start with a formal rotation, but as interest wanes, we en-courage everyone to be sure they’ve seen every picture To wrap things up,
we conduct a discussion about things they learned
H black yarn
A pictorial is a labeled diagram Creating one can introduce more informationabout frogs or to encourage children to collect facts from other sources Afteryou prepare the drawing on butcher paper and post it where everyone caneasily see it, there are several ways to handle the labeling process:
• Show-and-tell about each of the parts you’ll be labeling and ask for students’help spelling the words
• Print labels and ask for students’ help in figuring out where each of themshould be placed (In this case, you may want to string yarn from the label tothe proper body part If the work is posted low enough, children like mixing
up the labels and then using push pins to set everything back in place.)
• Post the drawing and ask children to look at your collection of books over acouple of days to find information about frog bodies that would produce in-teresting labels This display is particularly charming and engaging whenchildren print some or all of the labels themselves
Minds-On Experiences Songs, Poems & Books
Songs, poems, and books (fiction and nonfiction) add another dimension toany study There have been many excellent books about frogs and toads pub-lished for young children over the past two decades The best of them are
Trang 9simply written and beautifully illustrated with full-color photos We’ve included
a list of our current favorites on page 8 You may find some of these in your
school library or in the public library, along with others we haven’t listed
The most recent publications can also be ordered through Web booksellers
Did You Ever See a Frog? A Song About Frogs
Having lived through the frustration of not being able to find (or afford) good
factual books for our students, we’ve also included a frog song
Did you ever see a frog, a frog, a frog,
Did you ever see a frog with long
Did You Ever See a Frog?
(to the tune of “Did You Ever See a Lassie?”)
You’ll find this song printed on 11″ × 17″ sheets, which can either be bound to
make a big book, or backed on construction or butcher paper to make a wall
chart Did You Ever See a Frog? packs a lot of data into a small package, and
is easy to come back to several days in a row It does triple duty in our
class-rooms, setting foundations for children to approach some of the math lessons
with greater depth and investment, teaching science content and research
skills, and providing yet another source of literacy learning
Guided Writing
Once you’ve launched any sort of animal study, you’ll find that children
of-ten report some relevant news If your community is in an area that has a
pond or creek nearby, children may be able to find tadpoles or spot a frog or
two on a family outing If you occasionally write class news after children
have shared an experience, guide them in synthesizing the information into
short articles, one or two a week
Trang 103/20 Class News
If your mom ordad takes you tothe pond at thepark, you can findeggs in the water
There are tinytadpoles too
3/21 Class News
Dan found a toad
in his grandma’sgarden He held it
It was slipperyand gooey
Interactive Writing
Once your study is well underway, encourage children to express some of thenew things they’re learning about frogs and toads If your class has found someinteresting information about frogs or answered some of their own questions,you might conduct a bit of interactive writing In this sort of lesson the groupand the teacher help with the ideas and spelling as students (and the teacher)take turns writing the words This works particularly well when children are ex-cited about the topic and the amount of writing is held to a sentence or two Besure to post these short pieces beside questions that have been answered ornext to the pictures or books from which the information has been drawn
Independent Writing
You’re probably noticing that more independent writing is emerging fromyour students A word bank is often helpful in supporting these efforts Suchbanks are most effective when the words are brainstormed with the children
We ask for their help in spelling
What are they doing?

Pocket Chart Poetry

pocket chart poems (Blacklines

Many young children delight in simple poems We’ve included blacklines to
help you produce three poems, and we certainly encourage you to create
oth-ers If you can find or draw pictures to match, all the better Once children
are familiar with these poems, they love mixing the words up, one line at a
time, reading it the mixed-up way, and then trying to fix it.

In our classrooms, we display one poem at a time for several days, getting all
the learning mileage out of it that we can As interest fades, we replace it with
another The possibilities for teaching beginning reading strategies with these
po-ems are endless as children search for words that rhyme or words that start or
end with a particular letter or cluster, or locate words the teacher names
Words to Other Pocket Chart Poems

Frog & Toad Eyes Creating A Growing Pattern Chart
Creating a chart (see page 11) provides children with opportunities to revisit
what they’ve learned during your frog study, while enabling you to pose new
challenges This particular growing pattern chart begins with making a
con-struction paper frog or a toad, and usually takes 3 or 4 days (sometimes longer)
to complete Once the chart is finished, you can use it to pose additional math
problems over a period of several weeks
Making the Frogs & Toads
You’ll need
H 6″ × 6″ white squares (1 per child)
H 5″ × 5″ brown and green squares
(cut 20 of each)
H 2″ × 2″ white squares (2 per child)
H 1″ × 1″ black squares (2 per child)
H pencils, crayons, scissors, and glue
for children to share
H two 5′ lengths of 3′ wide butcher
paper (Place the 2 lengths side by
side and glue them together to form
a sheet 5′ long and about 6′ wide.)
Gather children into a circle where they can watch as you work, and show
them how to use the green or brown paper, in combination with the small
black and white squares, to create a simple paper frog or toad When finished,
each frog or toad should be glued to a 6″ square of white construction paper
Teacher I’ll need to start by drawing an outline of a frog’s body on my
paper If I did not know what shape a frog is, how could I find out?
Children Look in a book Look at the pictures on the wall.
Ask someone to help.
Trang 14Teacher Then I need to cut my frog out and use the white and black
paper to make eyes and eyeballs, like this:
Teacher Now I’ll glue the eyes on and use a black crayon to make the
frog’s mouth like this:
Teacher The last thing I’m going to do is glue my frog to a square of
white paper like this and put my name on the back.
You’ll need 15, 21, 28, or 36 frogs in order to complete a triangular ment so you may need to ask a few students to make an extra
arrange-Assembling the Triangular Arrangement
Once the frogs are finished and dried, gather your students into the sion area and call on children to assemble the frogs, one row at a time into atriangular arrangement As each row is complete, ask children how many frogsare in the row How many will be in the next row? How many eyes are in therow? How many eyes will be in the next row? How are they figuring it out?
discus-Creating Number Labels for the Chart
Solicit children’s help to label each row How many frogs are in each row?How many eyes?
What Do Children Notice About the Chart?
Another day, after the chart is assembled, ask children what they notice andrecord their observations on talking bubbles (These can either be written onthe spot or typed in large print and glued onto the chart for another day.)Come back to these a third day to read each observation aloud and ask stu-dents to determine where the child who volunteered the comment saw thatinformation
Writing Numbers and Counting by 2’s
Write the counting numbers across the bottom of the chart to 20 and havechildren help you circle the counting by 2’s numbers Be sure to help themrelate this counting pattern to the frogs’ eyes on the chart
Trang 15Frog and Toad Eyes
It’s like a half sandwich when your grandma cuts
it in triangles.
Up and down, it’s shrinking
by 1 every time.
The frogs go 1, 2, 3, 4, 5, 6, but the eyes go 2, 4, 6, 8, 10, and keep on going and going.
There are
42 eyes altogether.
If you look at the rows, it has 2 more eyes every time.
If you look at the rows, it has 1 more frog each time.
There are 21 altogether.
Counting by 2’s Chart Mystery Numbers
You’ll need
H Counting by 2’s: mystery numbers
sheets 1–2 (Blacklines 17–18, run a
copy of each sheet and glue them
side by side to the Frog & Toad
Eyes chart.)
First, ask children what they notice about the number sheets you’ve glued to
the Frog & Toad Eyes chart Once they’ve made some observations, point to
various boxes on the sheets and ask what number would go into a particular
blank square
Trang 16Frog & Toad Problems With the Counting By 2’s Chart
After the Frog & Toad Eyes chart has been up for a time, gather your studentsaround it and pose some problems such as the ones below
There were 3 frogs sitting on a log How many “bug detector” eyeswere searching for food?
There were 10 “bug detector” eyes searching for the slightest ment How many toads?
move-If we made some more frogs and toads and used them to create other row on our chart, how many frogs and toads would there be
an-in that row? How many eyes would they have? How do you know?

A Double Irish Chain Frog Quilt
Making a class quilt is always fun, and the wonder of watching it all come
to-gether as the product of community effort is exciting We’ve chosen the
Double Irish Chain pattern for this quilt because of the many mathematical
observations children can make as they study the finished quilt Plan on 3 or
4 days from start to finish for this project and then display the quilt for
every-one to enjoy If it’s your turn to decorate the office or the library, a quilt or a
growing number pattern chart will let visitors know how many ways your
children are experiencing mathematics
Making the Patchwork Quilt Blocks
Each student will need
H Double Irish Chain quilt block
(Blackline 19, run a class set)
H 4 squares 11⁄2″ × 11⁄2″ black
Note If you set the colored squares
out in baskets or trays at each table, children can count the squares they need as they’re ready for each color.
Make extra squares in case a group
runs out of one or more of the colors.
Gather your students into a circle or a “U” in the discussion area where all of
them can see your copy of the quilt block Show them the key at the bottom
of the sheet and explain that everyone will need to use the same colors as
shown in the key so that this quilt will be their best one yet Have them help
you count how many white squares you’ll need Place drops of glue in the
corners of all the white squares on the quilt block sheet and quickly attach
the construction paper squares to the paper Repeat the process with the black,
and then the green squares Hang your finished quilt block where everyone
can see it and then send children out to begin their own work As students
are finishing, have them check to be sure all their paper squares have been
glued in the correct places and are securely attached to the paper Ask
young-sters to put their names on their papers and set them in a specific location to

have the correct number of blocks to create a quilt as described above, you
might consider making one large quilt and a smaller one or two to give as gifts
to someone special
Quilt Observations
Once the quilt is assembled and glued, ask children what they notice and
record their observations in large print Post their comments beside the quilt
to create an impressive display
