3-5
A puzzle involving five dice and a non-standard pattern is used to promote problem-solving skills.
3-5
In this lesson, students discover the uses of geometry and measurement in the world of architecture as they are introduced to the clubhouse project.
3-5
Students will calculate differences in time zones and explore the effects of traveling across time zones.
3-5
In this lesson, students will use various resources to choose travel dates, compare temperatures, estimate and calculate distances to Belize City, and determine the length of their flight in preparation for a "trip" to Belize.
3-5
In this lesson, students will pretend to travel to the island of Ambergris Caye off the coast of Belize. Students will work together to complete the measurements needed for their scuba diving gear in preparation for the dives, and they will solve elapsed time problems.
3-5
Students will work in pairs on various measurement problems. They will complete linear conversions, find elapsed time, calculate a percentage, and analyze data from a chart.
Pre-K-2, 3-5
Students often view linear measurement as a procedure in which a number is simply read off a ruler. The goal of this lesson is to have students gain experience in linear measurement by using a variety of measuring instruments to measure the heights of classmates, to discover the error inherent in measurement, and to search for patterns in data that are represented on a table. In this lesson, students compare results of measuring the same height using different methods, and discuss measurement error. They measure the heights of classmates and the heights of older students in their school, and construct a table of height and age data. The lesson is also designed to serve as a springboard for a second lesson in which students relate measurement to algebra and data analysis concepts.
Pre-K-2, 3-5
A key goal for instruction on algebra at the elementary level is to analyze change, and to understand how change in one variable can relate to change in a second variable. The goal of this lesson is for students to explore how changes in students’ ages relate to changes in their heights.
3-5
In this lesson, students generate products using a number line model. Students are encouraged to predict the products and to answer puzzles involving multiplication.
3-5
Students continue their investigation of modeling multiplication on the number line using the Distance-Speed-Time Simulation from the NCTM E-Examples.
