lesson tasks
- TEACHER PREP: Using the “classroom measurement chart” as a guide, prepare a three-column chart on poster board. Column 1 is for the group name, Column 2 is for estimating the classroom size, and Column 3 is for actual measurements taken by the students.
- Begin by reviewing rulers and that there are twelve inches on the ruler. Explain that a ruler equals one foot.
- As each student looks at their ruler, ask the students to guess the size of their classroom (length and width) in feet.
- Discuss the need for a universal system of measurement. Explain that all across the country, everyone uses the same unit of measure.
- Demonstrate how to use a ruler to measure. Tell the students to line up the edge of the ruler to the edge of the object they are measuring. (This should be more of a review)
- Separate the students into groups of two.
- Have each group measure the wall lengths of the classroom. More than one group can measure the same wall by starting at opposite ends.
- All groups record their results on the poster board in the correct columns.
- Discuss the differences in measurements, and why they differ.
- Pull up the classroom floor plan activity on the smart board.
- Have students come up one by one to help recreate our classroom on the board.
- After creating the classroom, have the students return to their desks and distribute the graph paper.
- Using the actual measurements (not the estimate), have each child draw the classroom floor plan. One block on the graph paper equals one foot. The students should include furniture and indicate where doors and windows are located.
CCSS.ELA-Literacy.W.2.8: Recall information from experiences or gather information from provided sources to answer a question.
CCSS.ELA-Literacy.SL.2.1: Participate in collaborative conversations with diverse partners about grade 2 topics and texts with peers and adults in small and larger groups.
CCSS.Math.Content.2.MD.A.1: Measure the length of an object by selecting and using appropriate tools such as rulers, yardsticks, meter sticks, and measuring tapes.
CCSS.Math.Content.2.MD.D.9: Generate measurement data by measuring lengths of several objects to the nearest whole unit, or by making repeated measurements of the same object. Show the measurements by making a line plot, where the horizontal scale is marked off in whole-number units.
