Students will use beans and/or bean bags to practice their estimation and measurement skills. They will be able to measure distances to the nearest inch or foot.

Jim and the Beanstalk, by Raymond Briggs; ISBN-13:9780698115774
Students will use beans and/or bean bags to practice their estimation and measurement skills. They will be able to measure distances to the nearest inch or foot.
Review the following vocabulary with students:
1. Demonstrate a positive learning attitude.
2. Develop social skills and ethical responsibility.
Invitation to Learn
Have each student select a Ziploc bag from a basket. Each bag should contain approximately $1.50-$2.00 in coins as well as a small item. [Example: a paper clip, a birthday candle, a tongue depressor, etc.] Ask the students to measure the height of their desk from the floor to the top of their desk using the item inside their bag. They must now pay $0.05 for each measurement length if they want to use their desk for the remainder of the class period. Have students trade items with other students and measure using the various nonstandard items. Students will recognize that the smaller the unit, the more iterations needed to cover a given length. Have students record their findings in their Math Journals. Review with students that sometimes we use nonstandard units of measurement.
Instructional Procedures
Read Jim and the Beanstalk to the class. Discuss how Jim measures the different body parts and items in the book. Refer to the proportions of what is being measured and what unit of measurement is used.

Recent efforts to make the mathematics curriculum consistent with the National Council of Teachers of Mathematics "Standards" will fail unless teachers' beliefs about mathematics change. Teacher educators, school officials, political leaders, and teachers themselves must first acknowledge a serious problem with the way our society views mathematics. The next step is reforming the institutions affecting teachers' education and working environment.

This paper describes how one group of students developed personally meaningful ways to reason mathematically within the context of measurement. Episodes taken from a first grade classroom in which a 4-month teaching experiment was conducted are presented. One of the goals of the teaching experiment was to develop instructional sequences designed to support first grade students' construction of meaningful understandings for measurement and mental computation and estimation strategies for numbers up to 100. A primary focus when developing the instructional sequences was to support students' multiple interpretations of problem situations. The episodes provide a setting for the examination of measurement as a context for supporting students' construction of sophisticated ways to think and reason mathematically. The intent of the instructional sequences developed in the course of the teaching experiment is outlined first. The rest of the paper consists of descriptions of episodes from the classroom that highlight students' ability to reason mathematically while investigating issues related to measurement.
