Introductions Each person takes a turn. Roll the die and answer the question that corresponds to the number on the die. The other members, in turn, will ask you probing questions for more information. Each person takes a turn. Roll the die and answer the question that corresponds to the number on the die.

Measurement and Data (2.MD) Measure and estimate lengths in standard units. 1. Measure the length of an object by selecting and using appropriate tools such as rulers, yardsticks, meter sticks, and measuring tapes. 2. Measure the length of an object twice, using length units of different lengths for the two measurements; describe how the two measurements relate to the size of the unit chosen. 3. Estimate lengths using units of inches, feet, centimeters, and meters. 4. Measure to determine how much longer one object is than another, expressing the length difference in terms of a standard length unit.

Measurement and Data (3.MD) Represent and interpret data. 4. Generate measurement data by measuring lengths using rulers marked with halves and fourths of an inch. Show the data by making a line plot, where the horizontal scale is marked off in appropriate units— whole numbers, halves, or quarters.

Measurement and Data (3.MD) Geometric measurement: recognize perimeter as an attribute of plane figures and distinguish between linear and area measures. 8. Solve real world and mathematical problems involving perimeters of polygons, including finding the perimeter given the side lengths, finding an unknown side length, and exhibiting rectangles with the same perimeter and different areas or with the same area and different perimeters.

One- Dimensional Measurement Using your measuring tools you made, measure 5 items of different sizes from around the room.

What is the fewest number of straws needed to make a closed shape? Make shapes with different numbers of straws. Tape them to the construction paper. You may cut the straws to make a different length Make shapes with different numbers of straws. Tape them to the construction paper.

Literature Connection Read “How Big is a Foot” by Rolf Myller. Read “How Big is a Foot” by Rolf Myller. The King wants a bed for his queen and uses his foot to measure how big the bed should be. But his chief carpenter is much smaller and uses his foot measure to make the bed. The King wants a bed for his queen and uses his foot to measure how big the bed should be.

Read “How Tall, How Short, How Faraway by David Adler (1999) Read “How Tall, How Short, How Faraway by David Adler (1999) Introduces several measuring systems such as the Egyptian system, the inch-pound system, and the metric system.
