Math

__** Lesson 1 **__ __Objectives__: 1. Students will research the lengths of dinosaurs. 2. Students will create a bar graph showing the lengths of ten different dinosaurs. 3. Students will compare and contrast the lengths of dinosaurs. __ Materials __ : Computers, encyclopedias, chart paper, markers __Procedure:__ Students will work in pairs to research the lengths of ten different dinosaurs: Triceratops, Tyrannosaurus, Allosaurus, Ankylosaurus, Stegosaurus, Iguanodon, Archaoceratops, Vulcanodon, Wannonsaurus, and Argentinosaurus. Each pair of students will create a bar graph of the dinosaurs' lengths. Hang students bar graphs up around the room. Have students compare the lengths of dinosaurs.

__ Objectives __ : 1. Students will measure their weight with a bathroom scale. 2. Students will graph their weight on a bar graph. 3. Students will research and graph the weight of the ten dinosaurs from the day before. 4. Students will compare the two graphs. __ Materials __ : 6 bathroom scales, 2 bar graph templates for each group, markers, computers, encyclopedias __ Procedure __ : Explain that a pound is 16 ounces. Ask students what kinds of things they think we measure by pounds. In cooperative learning groups, have students weigh each other and graph it on one of the bar graph templates. Then, each group will research the dinosaurs from the day before to find out their weight and graph it. Have students compare their weight to the weight of the dinosaurs they researched.
 * __ Lesson 2 __**

__ Objectives __ : 1. Students will measure using standard units of inches and feet. 2. Students will measure using nonstandard units of measuring (feet and paperclips). __ Materials __ : Books, crayon boxes, desks, measuring tapes, math journals __ Procedure __ : Introduce the term foot to students. Ask students if they know how many inches make a foot. Explain to students that 12 inches is a foot. Have students show you twelve inches on their rulers. Tell Students that today they will work in groups to measure each other. They will record these measurements in their math journals. Each group will then choose a dinosaur from the previous days' bar graphs and use measuring tapes to measure the dinosaur's length. Next, students will use nonstandard units of measurement to measure. They will measure their crayon boxes, desk tops, and reading text book with paper clips. Answers will be recorded in math journals. Students will work in their groups and take turns measuring the length of the classroom with their feet. Students will record their results in their math journals and compare with other students in their group. Students will then have 5 minutes to share their results with as many people as they can in the classroom. When the timer goes off, all students must be in their seats.
 * __ Lesson 3 __**

__ Objectives __ : 1. Students will count using tally marks. 2. Students will make tally marks for the dinosaurs in their picture. __ Materials __ Dinosaur pictures, tally mark chart __Procedure__:Review with students that tally marks help people count. Each tally mark represents one object. For example, to count four balloons, you make four tally marks. Tally marks are grouped in sets of five, which helps us count faster. Instead of counting by ones, we count by fives and add on any remaining marks. Students will work together in cooperative learning groups. Each group is given a picture that has an assortment of dinosaurs. They must count the dinosaurs and make a chart with tally marks.
 * __ Lesson 4 __**

__ Objectives __ : 1. Students will estimate how many m&m's they can hold in their hand. 2. Students will estimate how many dinosaurs are in container. 3. Students will compare estimations. __ Materials __ 1 container of plastic toy dinosaurs for each group, math journals, paper, pencils scissors, m&m's __ Procedure __ : Ask students to think about how many m&m's they can hold in one hand. Have students share estimates with the class. Have students trace one of their hands, cut it out, and write their estimates on it. Students will place m&m's on their hand to see how many it will hold. Students will pair up and share their estimates and their results with a partner. The class will discuss the various sizes of hands and how many m&m's were held. Students will then work in cooperative learning groups to estimate how many dinosaurs are in their container. Students will write their estimates in their math journals. Then each group will count how many dinosaurs are in the container and record their answers. Students will compare their answers with their estimates.
