Working with older buddies, primary students become experts on eight species of bears. Students engage in a variety of comparison activities, including estimating and measuring the differences between themselves and bears. Students also compare the habitats, sizes, and needs of two bear species. Finally, students dig deeper to learn all they can about one bear species and apply their expertise as they make a guide for children who visit the local zoo.

View how a variety of student-centered assessments are used in the Meet the Bears Unit Plan. These assessments help students and teachers set goals; monitor student progress; provide feedback; assess thinking, processes, performances, and products; and reflect on learning throughout the learning cycle.
Getting to Know Bears
Prior to instruction, read the teacher background information for a basic introduction.
Check out a mixed collection of fiction and nonfiction books about bears. Arrange for study buddies from a fifth-grade class. Schedule times for older buddies to help younger students as they read, study, and write about bears.
- Give each student a large piece of folded construction paper. This folder will be kept throughout the entire unit to hold all papers and handouts. At the end of the unit, students can design a cover page for their folder. This may be used as an additional measure to assess students’ understanding of the unit.
- Keep a student vocabulary page so students can track the new vocabulary they learn. Keep a list of the vocabulary and definitions on a piece of chart paper for the class to see. Students copy definitions from the teacher’s chart, and draw and color pictures to represent each word.
To begin the unit, start by reading the book We’re Going on a Bear Hunt, by Michael Rosen. Have student volunteers or the whole class participate in a “bear hunt” with you by acting out the motions from the book.
After the bear hunt is finished, have students fill out the KNOW part of their Know-Wonder-Learn (K-W-L) chart. Students can write words or draw pictures to represent what they know. After students have been given enough time to fill out the KNOW section of their chart, have them give you their ideas as you record them on the class K-W-L chart. Use their responses as a means for discussion along the way. Spark students’ curiosity by asking the question, What more do you want to know about bears?
Have students fill out the WONDER section of their K-W-L chart. Give students time to fill out their chart. Bring the group back together and have students share their questions. Record them on the WONDER section of the class K-W-L chart. Keep the K-W-L chart posted for students to see throughout the unit. Make sure to come back to the questions as they are answered during the unit.Teach students the differences between fiction and nonfiction, and then engage in the following activity. Using a mixed set of books about bears, describe each book, and read the summary from the flyleaf or back cover. Ask questions, such as the following:
- Is this book fiction or nonfiction?
- How can you tell?
Introduce students to Internet navigation by having them engage in a bears scavenger hunt with a fifth-grade buddy at Bears at Enchanted Learning*. Post the Essential Question on a piece of chart paper, and challenge the students to answer the question, Are we like other animals? This question will elicit many ideas and can serve as the basis for a discussion about the characteristics of bears. Record thoughts and ideas on chart paper, and leave the chart paper posted so the class can add to it as the unit unfolds.To answer the Unit Question, What do animals need to live? have students learn the LAWS of the land. On a sheet of paper, have students write the word LAWS vertically down one side. Explain that what all living things need to survive can be summarized by the LAWS of the Land:
- L stands for land
- A stands for air
- W stands for water
- S stands for sun
Have students write the words and do a quick illustration for each word. Refer to LAWS throughout the unit as you talk about what bears need to live and survive.
Research time. Support teams as they spend the week researching questions about bears. Have students participate in a Bears Compare team study and contrast two bear species to answer the Content Questions:
- What do bears eat?
- What are a bear’s characteristics?
Brainstorm a list of everything that can be compared, such as size, lifespan, biome and habitat, habits, diet, growth and development, hibernation patterns, and whether a particular species is endangered. The compare the bears sheet can be used to record student responses. In addition, have students record the weight, length, and diet for each bear on large Bears Compare posters. The information from this activity is used in the upcoming Bears and Me activity.
Students study their topics using cooperative experts, such as wildlife biologists at the local ranger district, books, and Web sites like Bear Den*, Bears*, Polar Bears International*, and Bears at Enchanted Learning*. Students then present what they have learned to the class. As a break, consider using this mother bear movement activity*.
Bears and Me
This activity addresses the Unit Question, How are we different from bears? Use the Bears and Me sample as a guide for Activities 1 and 2. Have each student choose one bear species. Then, have students compare the bears to themselves.
- Activity 1: Compare What We Eat. Using information from the Bears Compare poster, have student pairs compare their diets to the diet of one bear species, and make a Venn diagram of similarities and differences. For a greater comparison, make a Venn diagram with three circles, comparing three bears. Show students how Venn diagrams display overlapping information by completing an example on chart paper for the whole class.
- Activity 2: Compare Our Size. (Prepare your computer projection system for this demonstration.) Ask the following questions:
- How many of us would it take to weigh the same as a bear?
- What do you want to know before you make your best guess?
Answer questions and write predictions on the board. Ask, How can we answer this question?
Refer to the weight data of the different bear species from the Bears Compare poster and ask students to choose which bear they want to be compared to. Weigh students one at a time, and guide students as they add the weights until the pounds add up to the weight of the bear. Have students being weighed stay in a cluster at the front of the room until weighing is complete. Next, have students work with buddies to do repeated addition (or multiplication) of their individual weights to see how many "Andrews," for instance, would be needed to weigh the same as one bear. Try to get all the species represented. Show students how the information can be shown in a spreadsheet, and model how the data can be presented in a graph or chart.
After students have their comparison to their bears, distribute the spreadsheet handout and have students walk around and ask each person how many of them it took to equal the bear’s size. Have students fill in their spreadsheet form to keep track of each person’s comparison. Use the spreadsheet student example and graphing student example to get an idea of what a finished product might look like. Have each student also create a graph that compares the student’s weight with the bear’s weight. The graphs are used later in the student brochures.
After both activities are completed, have students discuss in a pair-share format the Essential Question, Are we like other animals?
Have students take a few minutes to discuss their ideas together and record them on paper. Bring the discussion back to the whole group and add ideas to the chart paper created at the beginning of the unit. Have students get out their K-W-L chart and begin to fill out the LEARN section with what they have learned so far.Have students revisit the questions in the WONDER section to see if they have been answered yet. Have volunteers share some of their responses to add to the class K-W-L chart.
Develop linear measurement concepts with this activity. Cut a piece of string the length of the bear the students chose in the Bears and Me activity. Then have students find objects in the school that are the same length, smaller, or bigger than the string. Tell students to record their findings by listing the name of the object they are measuring and whether the object is bigger, smaller, or the same size as the bear. Have students illustrate the findings to show the comparison of size. Help students illustrate their findings on chart paper. In cooperative groups, have students and their buddies use butcher paper to create a life-sized image of their bear. Then, use butcher paper to trace and cut out each person in the group so students can compare their height to the height of the bear.
In this activity, the following Unit and Content Questions are reintroduced and answered:
- How are we different from bears?
- What do animals need to live?
- What do bears eat?
- What are a bear’s characteristics?
Students demonstrate their understanding of these questions by first completing research on a particular bear species and then summarizing the information in a brochure to be distributed at the local zoo. Before this lesson begins, show students how to use the bears brochure checklist as a guide for content and quality as they create their brochures. Go over the bears rubric so students are aware of what criteria you will be using to grade the brochures. Have students collect information about their bears’ habitats and compare the information with a bear found at The Bear Den*. Students color world maps showing where the various bear species live. Have buddies work together for the next part of this activity. Import a graphic of a bear, either by scanning original paintings or drawings by students or using photo galleries on the Internet (such as Pics4Learning*). Guide students as they research facts about their bears and record their findings on the bear facts recording sheet. Students use the information from this recording sheet when they create their brochures with their fifth-grade buddies.
Have students get into groups of four. Organize groups so each participant has a different bear. Have each student show his or her brochure picture and choose two facts about the bear to share with the group.
As a whole group, discuss the Essential Question, Are we like other animals? Have students give ideas as you record them on the class chart that you started at the beginning of the unit. Have students finish filling out the LEARN section of their K-W-L chart with at least two more facts or ideas they learned from the lesson.
Have students go back to the Essential Question—Are we like other animals?—and record their ideas for their folders. Tell them to use their folder contents, brochure, and any other handouts or resources they would like to use to help answer the question.
